  • HTML/CSS - Website Help.

    - by gabeaudick
    I'm trying to build my first website from scratch. I mocked up the design in Photoshop, and have been trying to convert into code for a few hours. But I haven't got far. In fact, I'm stuck on the header's navigation bar. It looks right, but it doesn't work. I'm using an unordered-inline list, and trying to link different rectangles in the header. I can't click on anything in the header, though. The code for the html and css files, and a mockup of the header, are below. Any advice on why the header bar isn't working would be much appreciated. Here's a link to the image: http://rookery9.aviary.com.s3.amazonaws.com/3961000/3961027_eb89_625x625.jpg *Ideally, you would be able to click on either "". home.html: <!DOCTYPE HTML PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" lang="en" xml:lang="en"> <head> <!-- Title --> <title>I am Gabe Audick.</title> <!-- Meta --> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <meta name="Author" content="Gabe Audick" /> <meta name="Copyright" content="Gabe Audick" /> <!-- Stylesheets --> <link href="style.css" media="screen" rel="stylesheet" type="text/css" /> <!-- RSS --> <link rel="alternate" type="application/rss+xml" title="gabeaudick RSS" href="http://feeds.feedburner.com/gabeaudick" /> </head> <body> <!-- Navigation Bar --> <div id="wrap"> <div id="header"> <ul> <li><a href="#">Previous</a></li> <li><a href="#">Home</a></li> <li><a href="#">Next</a></li> </ul> </div> </div> <!-- END --> <!-- Google Analytics --> <script type="text/javascript"> var _gaq = _gaq || []; _gaq.push(['_setAccount', 'UA-5899101-4']); _gaq.push(['_trackPageview']); (function() { var ga = document.createElement('script'); ga.type = 'text/javascript'; ga.async = true; ga.src = ('https:' == document.location.protocol ?

  • How to map an IDictionary<String, CustomCollectionType> in NHibernate

    - by devonlazarus
    Very close to what I'm trying to do but not quite the answer I think I'm looking for: How to map IDictionary<string, Entity> in Fluent NHibernate I'm trying to implement an IDictionary<String, IList<MyEntity>>and map this collection to the database using NHibernate. I do understand that you cannot map collections of collections directly in NHibernate, but I do need the functionality of accessing an ordered list of elements by key. I've implemented IUserCollectionType for my IList<MyEntity> so that I can use IDictionary<String, MyCustomCollectionType> but am struggling with how to get the map to work as I'd like. Details This is the database I'm trying to model: ------------------------ -------------------- | EntityAttributes | | Entities | ------------------------ ------------------ -------------------- | EntityAttributeId PK | | Attributes | | EntityId PK | <- | EntityId FK | ------------------ | DateCreated | | AttributeId FK | -> | AttributeId PK | -------------------- | AttributeValue | | AttributeName | ------------------------ ------------------ Here are my domain classes: public class Entity { public virtual Int32 Id { get; private set; } public virtual DateTime DateCreated { get; private set; } ... } public class EavEntity : Entity { public virtual IDictionary<String, EavEntityAttributeList> Attributes { get; protected set; } ... } public class EavAttribute : Entity { public virtual String Name { get; set; } ... } public class EavEntityAttribute : Entity { public virtual EavEntity EavEntity { get; private set; } public virtual EavAttribute EavAttribute { get; private set; } public virtual Object AttributeValue { get; set; } ... } public class EavEntityAttributeList : List<EavEntityAttribute> { } I've also implemented the NH-specific custom collection classes IUserCollectionType and PersistentList And here is my mapping so far: <hibernate-mapping xmlns="urn:nhibernate-mapping-2.2" ...> <class xmlns="urn:nhibernate-mapping-2.2" name="EavEntity" table="Entities"> <id name="Id" type="System.Int32"> <column name="EntityId" /> <generator class="identity" /> </id> ... <map cascade="all-delete-orphan" collection-type="EavEntityAttributeListType" name="EntityAttributes"> <key> <column name="EntityId" /> </key> <index type="System.String"> <column name="Name" /> </index> <one-to-many class="EavEntityAttributeList" /> </map> </class> </hibernate-mapping> I know the <map> tag is partially correct, but I'm not sure how to get NH to utilize my IUserCollectionType to persist the model to the database. What I'd like to see (and this isn't right, I know) is something like: <map cascade="all-delete-orphan" collection-type="EavEntityAttributeListType" name="EntityAttributes"> <key> <column name="EntityId" /> </key> <index type="System.String"> <column name="Name" /> </index> <list> <index column="DisplayOrder"> <one-to-many class="EntityAttributes"> </list> </map> Does anyone have any suggestions on how to properly map that IDictionary<String, EavEntityAttributeList> collection? I am using Fluent NH so I'll take examples using that library, but I'm hand mappings are just as helpful here.

  • Optimizing a 3D World Javascript Animation

    - by johnny
    Hi! I've recently come up with the idea to create a tag cloud like animation shaped like the earth. I've extracted the coastline coordinates from ngdc.noaa.gov and wrote a little script that displayed it in my browser. Now as you can imagine, the whole coastline consists of about 48919 points, which my script would individually render (each coordinate being represented by one span). Obviously no browser is capable of rendering this fluently - but it would be nice if I could render as much as let's say 200 spans (twice as much as now) on my old p4 2.8 Ghz (as a representative benchmark). Are there any javascript optimizations I could use in order to speed up the display of those spans? One 'coordinate': <div id="world_pixels"> <span id="wp_0" style="position:fixed; top:0px; left:0px; z-index:1; font-size:20px; cursor:pointer;cursor:hand;" onmouseover="magnify_world_pixel('wp_0');" onmouseout="shrink_world_pixel('wp_0');" onClick="set_askcue_bar('', 'new york')">new york</span> </div> The script: $(document).ready(function(){ world_pixels = $("#world_pixels span"); world_pixels.spin(); setInterval("world_pixels.spin()",1500); }); z = new Array(); $.fn.spin = function () { for(i=0; i<this.length; i++) { /*actual screen coordinates: x/y/z --> left/font-size/top 300/13/0 300/6/300 | / |/ 0/13/300 ----|---- 600/13/300 /| / | 300/20/300 300/13/600 */ /*scale font size*/ var resize_x = 1; /*scale width*/ var resize_y = 2.5; /*scale height*/ var resize_z = 2.5; var from_left = 300; var from_top = 20; /*actual math coordinates: 1 -1 | / |/ 1 ----|---- -1 /| / | 1 -1 */ //var get_element = document.getElementById(); //var font_size = parseInt(this.style.fontSize); var font_size = parseInt($(this[i]).css("font-size")); var left = parseInt($(this[i]).css("left")); if (coast_line_array[i][1]) { } else { var top = parseInt($(this[i]).css("top")); z[i] = from_top + (top - (300 * resize_z)) / (300 * resize_z); //global beacause it's used in other functions later on var top_new = from_top + Math.round(Math.cos(coast_line_array[i][2]/90*Math.PI) * (300 * resize_z) + (300 * resize_z)); $(this[i]).css("top", top_new); coast_line_array[i][3] = 1; } var x = resize_x * (font_size - 13) / 7; var y = from_left + (left- (300 * resize_y)) / (300 * resize_y); if (y >= 0) { this[i].phi = Math.acos(x/(Math.sqrt(x^2 + y^2))); } else { this[i].phi = 2*Math.PI - Math.acos(x/(Math.sqrt(x^2 + y^2))); i } this[i].theta = Math.acos(z[i]/Math.sqrt(x^2 + y^2 + z[i]^2)); var font_size_new = resize_x * Math.round(Math.sin(coast_line_array[i][4]/90*Math.PI) * Math.cos(coast_line_array[i][0]/180*Math.PI) * 7 + 13); var left_new = from_left + Math.round(Math.sin(coast_line_array[i][5]/90*Math.PI) * Math.sin(coast_line_array[i][0]/180*Math.PI) * (300 * resize_y) + (300 * resize_y)); //coast_line_array[i][6] = coast_line_array[i][7]+1; if ((coast_line_array[i][0] + 1) > 180) { coast_line_array[i][0] = -180; } else { coast_line_array[i][0] = coast_line_array[i][0] + 0.25; } $(this[i]).css("font-size", font_size_new); $(this[i]).css("left", left_new); } } resize_x = 1; function magnify_world_pixel(element) { $("#"+element).animate({ fontSize: resize_x*30+"px" }, { duration: 1000 }); } function shrink_world_pixel(element) { $("#"+element).animate({ fontSize: resize_x*6+"px" }, { duration: 1000 }); } I'd appreciate any suggestions to optimize my script, maybe there is even a totally different approach on how to go about this. The whole .js file which stores the array for all the coordinates is available on my page, the file is about 2.9 mb, so you might consider pulling the .zip for local testing: metaroulette.com/files/31218.zip metaroulette.com/files/31218.js P.S. the php I use to create the spans: <?php //$arbitrary_characters = array('a','b','c','ddsfsdfsdf','e','f','g','h','isdfsdffd','j','k','l','mfdgcvbcvbs','n','o','p','q','r','s','t','uasdfsdf','v','w','x','y','z','0','1','2','3','4','5','6','7','8','9',); $arbitrary_characters = array('cat','table','cool','deloitte','askcue','what','more','less','adjective','nice','clinton','mars','jupiter','testversion','beta','hilarious','lolcatz','funny','obama','president','nice','what','misplaced','category','people','religion','global','skyscraper','new york','dubai','helsinki','volcano','iceland','peter','telephone','internet', 'dialer', 'cord', 'movie', 'party', 'chris', 'guitar', 'bentley', 'ford', 'ferrari', 'etc', 'de facto'); for ($i=0; $i<96; $i++) { $arb_digits = rand (0,45); $arbitrary_character = $arbitrary_characters[$arb_digits]; //$arbitrary_character = "."; echo "<span id=\"wp_$i\" style=\"position:fixed; top:0px; left:0px; z-index:1; font-size:20px; cursor:pointer;cursor:hand;\" onmouseover=\"magnify_world_pixel('wp_$i');\" onmouseout=\"shrink_world_pixel('wp_$i');\" onClick=\"set_askcue_bar('', '$arbitrary_character')\">$arbitrary_character</span>\n"; } ?>

  • Fluent NHibermate and Polymorphism and a Newbie!

    - by Andy Baker
    I'm a fluent nhibernate newbie and I'm struggling mapping a hierarchy of polymorhophic objects. I've produced the following Model that recreates the essence of what I'm doing in my real application. I have a ProductList and several specialised type of products; public class MyProductList { public virtual int Id { get; set; } public virtual string Name {get;set;} public virtual IList<Product> Products { get; set; } public MyProductList() { Products = new List<Product>(); } } public class Product { public virtual int Id { get; set; } public virtual string ProductDescription {get;set;} } public class SizedProduct : Product { public virtual decimal Size {get;set;} } public class BundleProduct : Product { public virtual Product BundleItem1 {get;set;} public virtual Product BundleItem2 {get;set;} } Note that I have a specialised type of Product called BundleProduct that has two products attached. I can add any of the specialised types of product to MyProductList and a bundle Product can be made up of any of the specialised types of product too. Here is the fluent nhibernate mapping that I'm using; public class MyListMap : ClassMap<MyList> { public MyListMap() { Id(ml => ml.Id); Map(ml => ml.Name); HasManyToMany(ml => ml.Products).Cascade.All(); } } public class ProductMap : ClassMap<Product> { public ProductMap() { Id(prod => prod.Id); Map(prod => prod.ProductDescription); } } public class SizedProductMap : SubclassMap<SizedProduct> { public SizedProductMap() { Map(sp => sp.Size); } } public class BundleProductMap : SubclassMap<BundleProduct> { public BundleProductMap() { References(bp => bp.BundleItem1).Cascade.All(); References(bp => bp.BundleItem2).Cascade.All(); } } I haven't configured have any reverse mappings, so a product doesn't know which Lists it belongs to or which bundles it is part of. Next I add some products to my list; MyList ml = new MyList() { Name = "Example" }; ml.Products.Add(new Product() { ProductDescription = "PSU" }); ml.Products.Add(new SizedProduct() { ProductDescription = "Extension Cable", Size = 2.0M }); ml.Products.Add(new BundleProduct() { ProductDescription = "Fan & Cable", BundleItem1 = new Product() { ProductDescription = "Fan Power Cable" }, BundleItem2 = new SizedProduct() { ProductDescription = "80mm Fan", Size = 80M } }); When I persist my list to the database and reload it, the list itself contains the items I expect ie MyList[0] has a type of Product, MyList[1] has a type of SizedProduct, and MyList[2] has a type of BundleProduct - great! If I navigate to the BundleProduct, I'm not able to see the types of Product attached to the BundleItem1 or BundleItem2 instead they are always proxies to the Product - in this example BundleItem2 should be a SizedProduct. Is there anything I can do to resove this either in my model or the mapping? Thanks in advance for your help.

  • jqgrid retrieving empty rows using webapi (REST)

    - by polonskyg
    I'm using jqgrid in an ASPNET MVC4 project with WebApi (REST), Entity Framework 5 using Unit Of Work and Repository patterns. My problem is that I see the data flowing as json to the browser and I see three rows in the grid, but those rows are empty, and the data is not shown (three empty rows in the grid). This is method to get the data in the WebApi controller: public dynamic GetGridData(int rows, int page, string sidx, string sord) { var pageSize = rows; var index = sidx; var order = sord; var categories = Uow.Categories.GetAll().OrderBy(t => (string.IsNullOrEmpty(index) ? "Id" : index) + " " + (order ?? "desc")); var pageIndex = Convert.ToInt32(page) - 1; var totalRecords = categories.Count(); var totalPages = (int)Math.Ceiling((float) totalRecords / (float) pageSize); var categoriesPage = categories.Skip(pageIndex * pageSize).Take(pageSize).ToList(); return new { total = totalPages, page = page, records = totalRecords, rows = (from category in categoriesPage select new { id = category.Id.ToString(), cell = new string[] { category.Id.ToString(), category.Name, category.Description } }).ToArray() }; } This is the json received in the browser { "total": 1, "page": 1, "records": 3, "rows": [{ "id": "1", "cell": ["1", "Category 1", null] }, { "id": "3", "cell": ["3", "Category 3", "asAS"] }, { "id": "4", "cell": ["4", "Category 4", null] }] } This is the .js file with jqgrid jQuery("#ajaxGrid").jqGrid({ url: $("#ServiceUrl").val(), datatype: "json", jsonReader: { repeatitems: false, id: "Id" }, colNames: ['Id', 'Name', 'Description'], colModel: [ { name: 'id', editable: true, sortable: true, hidden: true, align: 'left' }, { name: 'name', editable: true, sortable: true, hidden: false, align: 'left' }, { name: 'description', editable: true, sortable: true, hidden: false, align: 'left' } ], mtype: 'GET', rowNum: 15, pager: '#ajaxGridPager', rowList: [10, 20, 50, 100], caption: 'List of Categories', imgpath: $("#ServiceImagesUrl").val(), altRows: true, shrinkToFit: true, viewrecords: true, autowidth: true, height: 'auto', error: function(x, e) { alert(x.readyState + " "+ x.status +" "+ e.msg); } }); function updateDialog(action) { return { url: $("#ServiceUrl").val(), closeAfterAdd: true, closeAfterEdit: true, afterShowForm: function (formId) { }, modal: true, onclickSubmit: function (params) { var list = $("#ajaxGrid"); var selectedRow = list.getGridParam("selrow"); params.url += "/" + list.getRowData(selectedRow).Id; params.mtype = action; }, width: "300", ajaxEditOptions: { contentType: "application/json" }, serializeEditData: function (data) { delete data.oper; return JSON.stringify(data); } }; } jQuery("#ajaxGrid").jqGrid( 'navGrid', '#ajaxGridPager', { add: true, edit: true, del: true, search: false, refresh: false }, updateDialog('PUT'), updateDialog('POST'), updateDialog('DELETE') ); BTW, If I want to return jqGridData instead the dynamic, How should I do it? Did is showing empty rows as well: public class jqGridData<T> where T : class { public int page { get; set; } public int records { get; set; } public IEnumerable<T> rows { get; set; } public decimal total { get; set; } } public jqGridData<Category> GetGridData(int rows, int page, string sidx, string sord) { var pageSize = rows; var index = sidx; var order = sord; var categories = Uow.Categories.GetAll().OrderBy(t => (string.IsNullOrEmpty(index) ? "Id" : index) + " " + (order ?? "desc")); var pageIndex = Convert.ToInt32(page) - 1; var totalRecords = categories.Count(); var totalPages = (int)Math.Ceiling((float)totalRecords / (float)pageSize); var categoriesPage = categories.Skip(pageIndex * pageSize).Take(pageSize); return new jqGridData<Category> { page = page, records = totalRecords, total = totalPages, rows = categoriesPage }; }

  • Anchor bug on IE9, anchor hitbox overlapped

    - by user1456399
    The menu below works just fine in Firefox and Chrome, but in IE9, but hitbox for the "HOME" anchor is being covered partially by the list item behind it except for the actual test, and a single horizontal pixel line at the top and bottom of the button. Can anyone see what I'm missing? Code to follow: index.html <html lang="en"> <head> <meta http-equiv="Content-Type" content="text/html;charset=utf-8" > <title>Navigation</title> <style> .menu-container { width:960px; height:45px; margin:0 auto; position:relative; z-index:2; background-color: #3d3d3d; margin-bottom: 20px; } .menu-navigation { font-family:Arial, Helvetica, sans-serif; font-size:13px; list-style:none; padding:0; margin:0; text-align: right; font-size: 0; /* Removes whitespace between <li> */ } .menu-navigation > li { display:inline; margin:0; border-left:solid 1px #242424; background-color:transparent; font-size: 12px; padding: 15px 0 15px 0; } .menu-navigation > li:hover, .menu-navigation > li.current-menu-item { background-color:#202020; } .menu-navigation > li.active, .menu-navigation > li.active:hover { background-color:#131313; } .menu-navigation > li a { text-decoration:none; color:#bbbbbb; } .menu-navigation > li a:hover { color:#efefef; } .menu-navigation > li span a { color:#ffffff; } .menu-navigation > li a:focus { outline:none; } .menu-navigation > li.menu-item-parent > span, .menu-navigation > li > span > a { text-transform:uppercase; outline:0; text-decoration:none; color:#ffffff; text-shadow:1px 1px 1px #000000; line-height: 45px; display: inline-block; height: 45px; padding: 0 20px 0 20px; } .menu-navigation > li.menu-item-parent > span { background:url("../img/down.png") no-repeat right center; } .menu-navigation > li.menu-item-parent > span:hover, .menu-navigation > li > span > a:hover { cursor:pointer; } </style> </head> <body> <div class="menu-container"> <ul class="menu-navigation"> <li><span><a href="#">This is a link</a></span></li> <li><span><a href="#">This is a link</a></span></li> <li class="menu-item-parent"><span>Not a link</span></li> <li class="menu-item-parent"><span>Not a link</span></li> <li class="menu-item-parent"><span>Not a link</span></li> </ul> </div> </body> </html> EDIT: Alright, I've changed the code to isolate the issue, and narrowed down the problem CSS. Simply adding a background image fixes the issue. The code is set up so it styles so the hit boxes for all the menu items are the same regardless if there's a link in them or not to facilitate an "onClick" drop down on those menu items without anchors. Refer to lines 81 - 86. Remove those lines (just a background image), and the hit box issue is seen in the menu items "NOT A LINK" as well. Further, the act of adding a background image fixes the hit box issue of "THIS IS A LINK" menu items. Simply add the following snippet to the CSS: .menu-navigation > li > span > a { background:url("../img/down.png") no-repeat right center; } Adding a background image, even if there is no actual image, is changing something with regards to the hit box... I'm just not sure what...

  • Explain the Peak and Flag Algorithm

    - by Isaac Levin
    EDIT Just was pointed that the requirements state peaks cannot be ends of Arrays. So I ran across this site http://codility.com/ Which gives you programming problems and gives you certificates if you can solve them in 2 hours. The very first question is one I have seen before, typically called the Peaks and Flags question. If you are not familiar A non-empty zero-indexed array A consisting of N integers is given. A peak is an array element which is larger than its neighbours. More precisely, it is an index P such that 0 < P < N - 1 and A[P - 1] < A[P] A[P + 1] . For example, the following array A: A[0] = 1 A[1] = 5 A[2] = 3 A[3] = 4 A[4] = 3 A[5] = 4 A[6] = 1 A[7] = 2 A[8] = 3 A[9] = 4 A[10] = 6 A[11] = 2 has exactly four peaks: elements 1, 3, 5 and 10. You are going on a trip to a range of mountains whose relative heights are represented by array A. You have to choose how many flags you should take with you. The goal is to set the maximum number of flags on the peaks, according to certain rules. Flags can only be set on peaks. What's more, if you take K flags, then the distance between any two flags should be greater than or equal to K. The distance between indices P and Q is the absolute value |P - Q|. For example, given the mountain range represented by array A, above, with N = 12, if you take: two flags, you can set them on peaks 1 and 5; three flags, you can set them on peaks 1, 5 and 10; four flags, you can set only three flags, on peaks 1, 5 and 10. You can therefore set a maximum of three flags in this case. Write a function that, given a non-empty zero-indexed array A of N integers, returns the maximum number of flags that can be set on the peaks of the array. For example, given the array above the function should return 3, as explained above. Assume that: N is an integer within the range [1..100,000]; each element of array A is an integer within the range [0..1,000,000,000]. Complexity: expected worst-case time complexity is O(N); expected worst-case space complexity is O(N), beyond input storage (not counting the storage required for input arguments). Elements of input arrays can be modified. So this makes sense, but I failed it using this code public int GetFlags(int[] A) { List<int> peakList = new List<int>(); for (int i = 0; i <= A.Length - 1; i++) { if ((A[i] > A[i + 1] && A[i] > A[i - 1])) { peakList.Add(i); } } List<int> flagList = new List<int>(); int distance = peakList.Count; flagList.Add(peakList[0]); for (int i = 1, j = 0, max = peakList.Count; i < max; i++) { if (Math.Abs(Convert.ToDecimal(peakList[j]) - Convert.ToDecimal(peakList[i])) >= distance) { flagList.Add(peakList[i]); j = i; } } return flagList.Count; } EDIT int[] A = new int[] { 7, 10, 4, 5, 7, 4, 6, 1, 4, 3, 3, 7 }; The correct answer is 3, but my application says 2 This I do not get, since there are 4 peaks (indices 1,4,6,8) and from that, you should be able to place a flag at 2 of the peaks (1 and 6) Am I missing something here? Obviously my assumption is that the beginning or end of an Array can be a peak, is this not the case? If this needs to go in Stack Exchange Programmers, I will move it, but thought dialog here would be helpful. EDIT

  • IE6 + IE7 CSS problem with overflow: hidden; - position: relative; combo.

    - by googletorp
    So I have created a slider for a homepage, that slides some images with a title and teaser text using jQuery. Everything works fine, and I went to check IE and found that IE 6 and 7 kills my slider css completely. I can't figure out why, but for some reason I can't hide the non active slides with overflow: hidden; I've tried tweaking the css back and forth, but haven't been able to figure out what's causing the problem. I've recreated the problem in a more isolated html page. <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="da" lang="da" dir="ltr"> <head> <style> body { width: 900px; } .column-1 { width: 500px; float: left; } .column-2 { width: 200px; float: left; } .column-3 { width: 200px; float: left; } ul { width: 2000px; left: -499px; position: relative; } li { list-style: none; display: block; float: left; } .item-list { overflow: hidden; width: 499px; } </style> </head> <body> <div class="column-1"> <div class="item-list clearfix"> <ul> <li class="first"> <div class="node-slide"> <img src="http://www.hanselman.com/blog/content/binary/lolcats-funny-pictures-leroy-jenkins.jpg" /> <div class="infobox"> <h4>Title 1</h4> <p>Teaser 1</p> </div> </div> </li> <li> <div class="slide"> <img src="http://www.hanselman.com/blog/content/binary/lolcats-funny-pictures-leroy-jenkins.jpg" /> <div class="infobox"> <h4>Title 2</h4> <p>Teaser 2</p> </div> </div> </li> <li class="last"> <div class="slide"> <img src="http://www.hanselman.com/blog/content/binary/lolcats-funny-pictures-leroy-jenkins.jpg" /> <div class="infobox"> <h4>Title 3</h4> <p>Teaser 3</p> </div> </div> </li> </ul> </div> </div> <div class="column-2"> ... </div> <div class="column-3"> ... </div> </body> </html> I've tracked down that it is the ul { position: relative; } on the ul element that is causing the overflow: hidden not to work, but why that is, I don't know. Also this is needed to make the slider javascript work using the left attribute on the ul to slide it. Any ideas as to how you can fix this is most welcome.

  • Wiring up JavaScript handlers after a Partial Postback in ASP.NET

    - by Richard
    I am trying to use LinkButtons with the DefaultButton property of the ASP.NET Panel in an UpdatePanel. I have read and used the various other answers that are around describing the wiring up of the click event so that a full postback is not done instead of a partial postback. When the page loads, I wire up the .click function of the LinkButton so that the DefaultButton property of the ASP.NET panel will work. This all works fine, until you bring an UpdatePanel into the mix. With an UpdatePanel, if there is a partial postback, the script to wire up the .click function is not called in the partial postback, and hitting enter reverts to causing a full submit of the form rather than triggering the LinkButton. How can I cause javascript to be executed after a partial postback to re-wire up the .click function of the LinkButton? I have produced a sample page which shows the problem. There are two alerts showing 1) When the code to hook up the .click function is being called, and 2) When the .click function has been called (this only happens when you hit enter in the textbox after the event has been wired up). To test this code, type something in the textbox and hit Enter. The text will be copied to the label control, but "Wiring up Event Click" alert will not be shown. Add another letter, hit enter again, and you'll get a full postback without the text being copied to the label control (as the LinkButton wasn't called). Because that was a full postback, the Wiring Up Event Click event will be called again, and the form will work properly the next time again. This is being done with ASP.NET 3.5. Test Case Code: <%@ Page Language="C#" Inherits="System.Web.UI.Page" Theme="" EnableTheming="false" AutoEventWireup="true" %> <script runat="server"> void cmdComplete_Click(object sender, EventArgs e) { lblOutput.Text = "Complete Pressed: " + txtInput.Text; } void cmdFirstButton_Click(object sender, EventArgs e) { lblOutput.Text = "First Button Pressed"; } protected override void OnLoad(EventArgs e) { HookupButton(cmdComplete); } void HookupButton(LinkButton button) { // Use the click event of the LinkButton to trigger the postback (this is used by the .click code below) button.OnClientClick = Page.ClientScript.GetPostBackEventReference(button, String.Empty); // Wire up the .click event of the button to call the onclick function, and prevent a form submit string clickString = string.Format(@" alert('Wiring up click event'); document.getElementById('{0}').click = function() {{ alert('Default button pressed'); document.getElementById('{0}').onclick(); }};", button.ClientID, Page.ClientScript.GetPostBackEventReference(button, "")); Page.ClientScript.RegisterStartupScript(button.GetType(), "click_hookup_" + button.ClientID, clickString, true); } </script> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html> <head> <title>DefaultButton/LinkButton Testing</title> <style type="text/css"> a.Button { line-height: 2em; padding: 5px; border: solid 1px #CCC; background-color: #EEE; } </style> </head> <body> <h1> DefaultButton/LinkButton Testing</h1> <form runat="server"> <asp:ScriptManager runat="server" /> <asp:UpdatePanel ID="UpdatePanel1" runat="server"> <ContentTemplate> <div style="position: relative"> <fieldset> <legend>Output</legend> <asp:Label runat="server" ID="lblOutput" /> </fieldset> <asp:Button runat="server" Text="First Button" ID="cmdFirstButton" OnClick="cmdFirstButton_Click" UseSubmitBehavior="false" /> <asp:Panel ID="Panel1" runat="server" DefaultButton="cmdComplete"> <label> Enter Text:</label> <asp:TextBox runat="server" ID="txtInput" /> <asp:LinkButton runat="server" CssClass="Button" ID="cmdComplete" OnClick="cmdComplete_Click" Text="Complete" /> </asp:Panel> </div> </ContentTemplate> </asp:UpdatePanel> <asp:Button runat="server" ID="cmdFullPostback" Text="Full Postback" /> </form> </body> </html>

  • performing authorisation/authentication between webservices

    - by mary
    Hi, i am developing webservices.In that i want to maintain state information so that all WebMethods could be access only after Login. I have tried but getting problem. I am attaching my code. Any other alternative will also be welcomed. [ WebService(Namespace = "http://amSubfah.org/")] [ WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)] // To allow this Web Service to be called from script, using ASP.NET AJAX, uncomment the following line. // [System.Web.Script.Services.ScriptService] public class Login : System.Web.Services.WebService { Message msgObj = new Message(); BaseClass b = new BaseClass(); PasswordEncryptionDecryption pedObj = new PasswordEncryptionDecryption(); public AuthHeader Authentication=new AuthHeader (); public Login () { //Uncomment the following line if using designed components //InitializeComponent(); } [ SoapHeader("Authentication", Required = true)] [System.Web.Services.

  • JSTL c:forEach causes @ViewScoped bean to invoke @PostConstruct on every request

    - by Nitesh Panchal
    Hello, Again i see that the @PostConstruct is firing every time even though no binding attribute is used. See this code :- <?xml version='1.0' encoding='UTF-8' ?> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xmlns:h="http://java.sun.com/jsf/html" xmlns:ui="http://java.sun.com/jsf/facelets" xmlns:c="http://java.sun.com/jsp/jstl/core"> <h:head> <title>Facelet Title</title> </h:head> <h:body> <h:form> <c:forEach var="item" items="#{TestBean.listItems}"> <h:outputText value="#{item}"/> </c:forEach> <h:commandButton value="Click" actionListener="#{TestBean.actionListener}"/> </h:form> </h:body> </html> And this is the simplest possible bean in JSF :- package managedBeans; import java.io.Serializable; import java.util.ArrayList; import java.util.List; import javax.annotation.PostConstruct; import javax.faces.bean.ManagedBean; import javax.faces.bean.ViewScoped; @ManagedBean(name="TestBean") @ViewScoped public class TestBean implements Serializable { private List<String> listItems; public List<String> getListItems() { return listItems; } public void setListItems(List<String> listItems) { this.listItems = listItems; } public TestBean() { } @PostConstruct public void init(){ System.out.println("Post Construct fired!"); listItems = new ArrayList<String>(); listItems.add("Mango"); listItems.add("Apple"); listItems.add("Banana"); } public void actionListener(){ System.out.println("Action Listener fired!"); } } Do you see any behaviour that should cause postconstruct callback to fire each time? I think JSF 2.0 is highly unstable. If it has to fire PostConstruct each and every time what purpose does @ViewScoped serve. Why not to use @RequestScoped only? I thought i have made some mistake in my application. But when i created this simplest possible in JSF, i still get this error. Am i not understanding the scopes of JSF? or are they not testing it properly? Further, if you remove c:forEach and replace it with ui:repeat, then it works fine. Waiting for replies to confirm whether it is bug or it is intentional to stop the programmers from using jstl?

  • ASP.net MVC 2.0 using the same form for adding and editing.

    - by Chevex
    I would like to use the same view for editing a blog post and adding a blog post. However, I'm having an issue with the ID. When adding a blog post, I have no need for an ID value to be posted. When model binding binds the form values to the BlogPost object in the controller, it will auto-generate the ID in entity framework entity. When I am editing a blog post I DO need a hidden form field to store the ID in so that it accompanies the next form post. Here is the view I have right now. <% using (Html.BeginForm("CommitEditBlogPost", "Admin")) { %> <% if (Model != null) { %> <%: Html.HiddenFor(x => x.Id)%> <% } %> Title:<br /> <%: Html.TextBoxFor(x => x.Title, new { Style = "Width: 90%;" })%> <br /> <br /> Summary:<br /> <%: Html.TextAreaFor(x => x.Summary, new { Style = "Width: 90%; Height: 50px;" }) %> <br /> <br /> Body:<br /> <%: Html.TextAreaFor(x => x.Body, new { Style = "Height: 250px; Width: 90%;" })%> <br /> <br /> <input type="submit" value="Submit" /> <% } %> Right now checking if the model is coming in NULL is a great way to know if I'm editing a blog post or adding one, because when I'm adding one it will be null as it hasn't been created yet. The problem comes in when there is an error and the entity is invalid. When the controller renders the form after an invalid model the Model != null evaluates to false, even though we are editing a post and there is clearly a model. If I render the hidden input field for ID when adding a post, I get an error stating that the ID can't be null. Any help is appreciated. EDIT: I went with OJ's answer for this question, however I discovered something that made me feel silly and I wanted to share it just in case anyone was having a similar issue. The page the adds/edits blogs does not even need a hidden field for id, ever. The reason is because when I go to add a blog I do a GET to this relative URL BlogProject/Admin/AddBlogPost This URL does not contain an ID and the action method just renders the page. The page does a POST to the same URL when adding the blog post. The incoming BlogPost entity has a null Id and is generated by EF during save changes. The same thing happens when I edit blog posts. The URL is BlogProject/Admin/EditBlogPost/{Id} This URL contains the id of the blog post and since the page is posting back to the exact same URL the id goes with the POST to the action method that executes the edit. The only problem I encountered with this is that the action methods cannot have identical signatures. [HttpGet] public ViewResult EditBlogPost(int Id) { } [HttpPost] public ViewResult EditBlogPost(int Id) { } The compiler will yell at you if you try to use these two methods above. It is far too convenient that the Id will be posted back when doing a Html.BeginForm() with no arguments for action or controller. So rather than change the name of the POST method I just modified the arguments to include a FormCollection. Like this: [HttpPost] public ViewResult EditBlogPost(int Id, FormCollection formCollection) { // You can then use formCollection as the IValueProvider for UpdateModel() // and TryUpdateModel() if you wish. I mean, you might as well use the // argument since you're taking it. } The formCollection variable is filled via model binding with the same content that Request.Form would be by default. You don't have to use this collection for UpdateModel() or TryUpdateModel() but I did just so I didn't feel like that collection was pointless since it really was just to make the method signature different from its GET counterpart. Thanks for the help guys!

  • Increasing speed of python code

    - by Curious2learn
    Hi, I have some python code that has many classes. I used cProfile to find that the total time to run the program is 68 seconds. I found that the following function in a class called Buyers takes about 60 seconds of those 68 seconds. I have to run the program about 100 times, so any increase in speed will help. Can you suggest ways to increase the speed by modifying the code? If you need more information that will help, please let me know. def qtyDemanded(self, timePd, priceVector): '''Returns quantity demanded in period timePd. In addition, also updates the list of customers and non-customers. Inputs: timePd and priceVector Output: count of people for whom priceVector[-1] < utility ''' ## Initialize count of customers to zero ## Set self.customers and self.nonCustomers to empty lists price = priceVector[-1] count = 0 self.customers = [] self.nonCustomers = [] for person in self.people: if person.utility >= price: person.customer = 1 self.customers.append(person) else: person.customer = 0 self.nonCustomers.append(person) return len(self.customers) self.people is a list of person objects. Each person has customer and utility as its attributes. EDIT - responsed added ------------------------------------- Thanks so much for the suggestions. Here is the response to some questions and suggestions people have kindly made. I have not tried them all, but will try others and write back later. (1) @amber - the function is accessed 80,000 times. (2) @gnibbler and others - self.people is a list of Person objects in memory. Not connected to a database. (3) @Hugh Bothwell cumtime taken by the original function - 60.8 s (accessed 80000 times) cumtime taken by the new function with local function aliases as suggested - 56.4 s (accessed 80000 times) (4) @rotoglup and @Martin Thomas I have not tried your solutions yet. I need to check the rest of the code to see the places where I use self.customers before I can make the change of not appending the customers to self.customers list. But I will try this and write back. (5) @TryPyPy - thanks for your kind offer to check the code. Let me first read a little on the suggestions you have made to see if those will be feasible to use. EDIT 2 Some suggested that since I am flagging the customers and noncustomers in the self.people, I should try without creating separate lists of self.customers and self.noncustomers using append. Instead, I should loop over the self.people to find the number of customers. I tried the following code and timed both functions below f_w_append and f_wo_append. I did find that the latter takes less time, but it is still 96% of the time taken by the former. That is, it is a very small increase in the speed. @TryPyPy - The following piece of code is complete enough to check the bottleneck function, in case your offer is still there to check it with other compilers. Thanks again to everyone who replied. import numpy class person(object): def __init__(self, util): self.utility = util self.customer = 0 class population(object): def __init__(self, numpeople): self.people = [] self.cus = [] self.noncus = [] numpy.random.seed(1) utils = numpy.random.uniform(0, 300, numpeople) for u in utils: per = person(u) self.people.append(per) popn = population(300) def f_w_append(): '''Function with append''' P = 75 cus = [] noncus = [] for per in popn.people: if per.utility >= P: per.customer = 1 cus.append(per) else: per.customer = 0 noncus.append(per) return len(cus) def f_wo_append(): '''Function without append''' P = 75 for per in popn.people: if per.utility >= P: per.customer = 1 else: per.customer = 0 numcustomers = 0 for per in popn.people: if per.customer == 1: numcustomers += 1 return numcustomers

  • MVC 3 Remote Validation jQuery error on submit

    - by Richard Reddy
    I seem to have a weird issue with remote validation on my project. I am doing a simple validation check on an email field to ensure that it is unique. I've noticed that unless I put the cursor into the textbox and then remove it to trigger the validation at least once before submitting my form I will get a javascript error. e[h] is not a function jquery.min.js line 3 If I try to resubmit the form after the above error is returned everything works as expected. It's almost like the form tried to submit before waiting for the validation to return or something. Am I required to silently fire off a remote validation request on submit before submitting my form? Below is a snapshot of the code I'm using: (I've also tried GET instead of POST but I get the same result). As mentioned above, the code works fine but the form returns a jquery error unless the validation is triggered at least once. Model: public class RegisterModel { [Required] [Remote("DoesUserNameExist", "Account", HttpMethod = "POST", ErrorMessage = "User name taken.")] [Display(Name = "User name")] public string UserName { get; set; } [Required] [Display(Name = "Firstname")] public string Firstname { get; set; } [Display(Name = "Surname")] public string Surname { get; set; } [Required] [Remote("DoesEmailExist", "Account", HttpMethod = "POST", ErrorMessage = "Email taken.", AdditionalFields = "UserName")] [Display(Name = "Email address")] public string Email { get; set; } [StringLength(100, ErrorMessage = "The {0} must be at least {2} characters long.", MinimumLength = 8)] [DataType(DataType.Password)] [Display(Name = "Password")] public string Password { get; set; } [StringLength(100, ErrorMessage = "The {0} must be at least {2} characters long.", MinimumLength = 8)] [DataType(DataType.Password)] [Display(Name = "Confirm password")] public string ConfirmPassword { get; set; } [Display(Name = "Approved?")] public bool IsApproved { get; set; } } public class UserRoleModel { [Display(Name = "Assign Roles")] public IEnumerable<RoleViewModel> AllRoles { get; set; } public RegisterModel RegisterUser { get; set; } } Controller: // POST: /Account/DoesEmailExist // passing in username so that I can ignore the same email address for the same user on edit page [HttpPost] public JsonResult DoesEmailExist([Bind(Prefix = "RegisterUser.Email")]string Email, [Bind(Prefix = "RegisterUser.UserName")]string UserName) { var user = Membership.GetUserNameByEmail(Email); if (!String.IsNullOrEmpty(UserName)) { if (user == UserName) return Json(true); } return Json(user == null); } View: <script src="//ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js" type="text/javascript"></script> <script src="//ajax.googleapis.com/ajax/libs/jqueryui/1.8.17/jquery-ui.min.js" type="text/javascript"></script> <script type="text/javascript" src="/Content/web/js/jquery.unobtrusive-ajax.min.js"></script> <script type="text/javascript" src="/Content/web/js/jquery.validate.min.js"></script> <script type="text/javascript" src="/Content/web/js/jquery.validate.unobtrusive.min.js"></script> ...... @using (Html.BeginForm()) { @Html.AntiForgeryToken() <div class="titleh"> <h3>Edit a user account</h3> </div> <div class="body"> @Html.HiddenFor(model => model.RegisterUser.UserName) @Html.Partial("_CreateOrEdit", Model) <div class="st-form-line"> <span class="st-labeltext">@Html.LabelFor(model => model.RegisterUser.IsApproved)</span> @Html.RadioButtonFor(model => model.RegisterUser.IsApproved, true, new { @class = "uniform" }) Active @Html.RadioButtonFor(model => model.RegisterUser.IsApproved, false, new { @class = "uniform" }) Disabled <div class="clear"></div> </div> <div class="button-box"> <input type="submit" name="submit" value="Save" class="st-button"/> @Html.ActionLink("Back to List", "Index", null, new { @class = "st-clear" }) </div> </div> } CreateEdit Partial View @model Project.Domain.Entities.UserRoleModel <div class="st-form-line"> <span class="st-labeltext">@Html.LabelFor(m => m.RegisterUser.Firstname)</span> @Html.TextBoxFor(m => m.RegisterUser.Firstname, new { @class = "st-forminput", @style = "width:300px" }) @Html.ValidationMessageFor(m => m.RegisterUser.Firstname) <div class="clear"></div> </div> <div class="st-form-line"> <span class="st-labeltext">@Html.LabelFor(m => m.RegisterUser.Surname)</span> @Html.TextBoxFor(m => m.RegisterUser.Surname, new { @class = "st-forminput", @style = "width:300px" }) @Html.ValidationMessageFor(m => m.RegisterUser.Surname) <div class="clear"></div> </div> <div class="st-form-line"> <span class="st-labeltext">@Html.LabelFor(m => m.RegisterUser.Email)</span> @Html.TextBoxFor(m => m.RegisterUser.Email, new { @class = "st-forminput", @style = "width:300px" }) @Html.ValidationMessageFor(m => m.RegisterUser.Email) <div class="clear"></div> </div> Thanks, Rich

  • MVC SiteMap - when different nodes point to same action SiteMap.CurrentNode does not map to the correct route

    - by awrigley
    Setup: I am using ASP.NET MVC 4, with mvcSiteMapProvider to manage my menus. I have a custom menu builder that evaluates whether a node is on the current branch (ie, if the SiteMap.CurrentNode is either the CurrentNode or the CurrentNode is nested under it). The code is included below, but essentially checks the url of each node and compares it with the url of the currentnode, up through the currentnodes "family tree". The CurrentBranch is used by my custom menu builder to add a class that highlights menu items on the CurrentBranch. The Problem: My custom menu works fine, but I have found that the mvcSiteMapProvider does not seem to evaluate the url of the CurrentNode in a consistent manner: When two nodes point to the same action and are distinguished only by a parameter of the action, SiteMap.CurrentNode does not seem to use the correct route (it ignores the distinguishing parameter and defaults to the first route that that maps to the action defined in the node). Example of the Problem: In an app I have Members. A Member has a MemberStatus field that can be "Unprocessed", "Active" or "Inactive". To change the MemberStatus, I have a ProcessMemberController in an Area called Admin. The processing is done using the Process action on the ProcessMemberController. My mvcSiteMap has two nodes that BOTH map to the Process action. The only difference between them is the alternate parameter (such are my client's domain semantics), that in one case has a value of "Processed" and in the other "Unprocessed": Nodes: <mvcSiteMapNode title="Process" area="Admin" controller="ProcessMembers" action="Process" alternate="Unprocessed" /> <mvcSiteMapNode title="Change Status" area="Admin" controller="ProcessMembers" action="Process" alternate="Processed" /> Routes: The corresponding routes to these two nodes are (again, the only thing that distinguishes them is the value of the alternate parameter): context.MapRoute( "Process_New_Members", "Admin/Unprocessed/Process/{MemberId}", new { controller = "ProcessMembers", action = "Process", alternate="Unprocessed", MemberId = UrlParameter.Optional } ); context.MapRoute( "Change_Status_Old_Members", "Admin/Members/Status/Change/{MemberId}", new { controller = "ProcessMembers", action = "Process", alternate="Processed", MemberId = UrlParameter.Optional } ); What works: The Html.ActionLink helper uses the routes and produces the urls I expect: @Html.ActionLink("Process", MVC.Admin.ProcessMembers.Process(item.MemberId, "Unprocessed") // Output (alternate="Unprocessed" and item.MemberId = 12): Admin/Unprocessed/Process/12 @Html.ActionLink("Status", MVC.Admin.ProcessMembers.Process(item.MemberId, "Processed") // Output (alternate="Processed" and item.MemberId = 23): Admin/Members/Status/Change/23 In both cases the output is correct and as I expect. What doesn't work: Let's say my request involves the second option, ie, /Admin/Members/Status/Change/47, corresponding to alternate = "Processed" and a MemberId of 47. Debugging my static CurrentBranch property (see below), I find that SiteMap.CurrentNode shows: PreviousSibling: null Provider: {MvcSiteMapProvider.DefaultSiteMapProvider} ReadOnly: false ResourceKey: "" Roles: Count = 0 RootNode: {Home} Title: "Process" Url: "/Admin/Unprocessed/Process/47" Ie, for a request url of /Admin/Members/Status/Change/47, SiteMap.CurrentNode.Url evaluates to /Admin/Unprocessed/Process/47. Ie, it is ignorning the alternate parameter and using the wrong route. CurrentBranch Static Property: /// <summary> /// ReadOnly. Gets the Branch of the Site Map that holds the SiteMap.CurrentNode /// </summary> public static List<SiteMapNode> CurrentBranch { get { List<SiteMapNode> currentBranch = null; if (currentBranch == null) { SiteMapNode cn = SiteMap.CurrentNode; SiteMapNode n = cn; List<SiteMapNode> ln = new List<SiteMapNode>(); if (cn != null) { while (n != null && n.Url != SiteMap.RootNode.Url) { // I don't need to check for n.ParentNode == null // because cn != null && n != SiteMap.RootNode ln.Add(n); n = n.ParentNode; } // the while loop excludes the root node, so add it here // I could add n, that should now be equal to SiteMap.RootNode, but this is clearer ln.Add(SiteMap.RootNode); // The nodes were added in reverse order, from the CurrentNode up, so reverse them. ln.Reverse(); } currentBranch = ln; } return currentBranch; } } The Question: What am I doing wrong? The routes are interpreted by Html.ActionLlink as I expect, but are not evaluated by SiteMap.CurrentNode as I expect. In other words, in evaluating my routes, SiteMap.CurrentNode ignores the distinguishing alternate parameter.

  • Need help displaying a dynamic table

    - by Gideon
    I am designing a job rota planner for a company and need help displaying a dynamic table containing the staff details. I have the following tables in MySQL database: Staff, Event, and Job. The staff table holds staff details (staffed, name, address...etc), the Event table (eventide, eventName, Fromdate, Todate...etc) and the Job table holds (Jobid, Jobdate, Eventid(fk), Staffid (fk)). I need to dynamically display the available staff list from the staff table when the user selects the EVENT and the DATE (3 drop downs: date, month, and year) from a PHP form. I need to display staff members that have not been assigned work on the selected date by checking the Jobdate in the Job table. I have been at this for all day and can't get around it. I am still learning PHP and would surely appreciate any help I can get. My current code displays all staff members when an event is selected: if(isset($_POST['submit'])) { $eventId = $_POST['eventradio']; } $timePeriod = $_POST['timeperiod']; $Day = $_POST['day']; $Month = $_POST['month']; $Year = $_POST['year']; $dateValue = $Year."-".$Month."-".$Day; $selectedDate = date("Y-m-d", strtotime($dateValue)); //construct the available staff list if ($selectedDate) { $staffsql = "SELECT s.StaffId, s.LastName, s.FirstName FROM Staff s WHERE s.StaffId NOT IN (SELECT J.StaffId FROM Job J WHERE J.JobDate != ".$selectedDate.")"; $staffResult = mysql_query($staffsql) or die (mysql_error()); } if ($staffResult){ echo "<p><table cellspacing='1' cellpadding='3'>"; echo "<th colspan=6>List of Available Staff</th>"; echo "</tr><tr><th> Select</th><th>Id</th><th></th><th>Last Name </th><th></th><th>First Name </th></tr>"; while ($staffarray = mysql_fetch_array($staffResult)) { echo "<tr onMouseOver= this.bgColor = 'red' onMouseOut =this.bgColor = 'white' bgcolor= '#FFFFFF'> <td align=center><input type='checkbox' name='selectbox[]' id='selectbox[]' value=".$staffarray['StaffId']."> </td><td align=left>".$staffarray['StaffId']." </td><td>&nbsp&nbsp</td><td align=center>".$staffarray['LastName']." </td><td>&nbsp&nbsp</td><td align=center>".$staffarray['FirstName']." </td></tr>"; } echo "</table>"; } else { echo "<br> The Staff list can not be displayed!"; } echo "</td></tr>"; echo "<tr><td></td>"; echo "<td align=center><input type='submit' name='Submit' value='Assign Staff'>&nbsp&nbsp"; echo "<input type='reset' value='Start Over'>"; echo "</td></tr>"; echo "</table>";

  • Facelet selectOneMenu with POJOs and converter problem

    - by c0d3x
    Hi, I want to have a facelet page with a formular and a dropdown menu. With the dropdown menu the user shoul select a POJO of the type Lieferant: public class Lieferant extends AbstractPersistentWarenwirtschaftsObject { private String firma; public Lieferant(WarenwirtschaftDatabaseLayer database, String firma) { this(database, null, firma); } public Lieferant(WarenwirtschaftDatabaseLayer database, Long primaryKey, String firma) { super(database, primaryKey); this.firma = firma; } public String getFirma() { return firma; } @Override public String toString() { return getFirma(); } @Override public int hashCode() { final int prime = 31; int result = 1; result = prime * result + ((firma == null) ? 0 : firma.hashCode()); return result; } @Override public boolean equals(Object obj) { if (this == obj) return true; if (obj == null) return false; if (getClass() != obj.getClass()) return false; Lieferant other = (Lieferant) obj; if (firma == null) { if (other.firma != null) return false; } else if (!firma.equals(other.firma)) return false; return true; } } Here is the facelet code that I wrote: <h:selectOneMenu> tag. This tag should display a list of POJOs (not beans) of the type Lieferant. Here is the facelet code: <h:selectOneMenu id="lieferant" value="#{lieferantenBestellungBackingBean.lieferant}"> <f:selectItems var="lieferant" value="#{lieferantenBackingBean.lieferanten}" itemLabel="#{lieferant.firma}" itemValue="#{lieferant.primaryKey}" /> <f:converter converterId="LieferantConverter" /> </h:selectOneMenu> Here is the refenrenced managed backing bean @ManagedBean @RequestScoped public class LieferantenBackingBean extends AbstractWarenwirtschaftsBackingBean { private List<Lieferant> lieferanten; public List<Lieferant> getLieferanten() { if (lieferanten == null) { lieferanten = getApplication().getLieferanten(); } return lieferanten; } } As far as I know, I need a custom converter, to swap beetween POJO and String representations of the Lieferant objects. Here is what the converter looks like: @FacesConverter(value="LieferantConverter") public class LieferantConverter implements Converter { @Override public Object getAsObject(FacesContext context, UIComponent component, String value) { long primaryKey = Long.parseLong(value); WarenwirtschaftApplicationLayer application = WarenwirtschaftApplication.getInstance(); Lieferant lieferant = application.getLieferant(primaryKey); return lieferant; } @Override public String getAsString(FacesContext context, UIComponent component, Object value) { return value.toString(); } } The page loads without any error. When I fill out the formular and submit it, there is an error message displayed on the page: Bestellung:lieferantenBestellungForm:lieferant: Validierungsfehler: Wert ist keine gültige Auswahl translated: validation error: value is not a valid selection Unfortunaltely it does not say which value it is talking about. The converter seems to work correctly. I found this similar question from stackoverflow and this article about selectOneMenu and converters, but I was not able to find the problem in my code. Why is List<SelectItem> used in the example from the second link. Gives the same error for me. Any help would be appreciated. Thanks in advance.

  • Yet another bug of JSF?

    - by Nitesh Panchal
    Hello, Again i see that the @PostConstruct is firing every time even though no binding attribute is used. See this code :- <?xml version='1.0' encoding='UTF-8' ?> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xmlns:h="http://java.sun.com/jsf/html" xmlns:ui="http://java.sun.com/jsf/facelets" xmlns:c="http://java.sun.com/jsp/jstl/core"> <h:head> <title>Facelet Title</title> </h:head> <h:body> <h:form> <c:forEach var="item" items="#{TestBean.listItems}"> <h:outputText value="#{item}"/> </c:forEach> <h:commandButton value="Click" actionListener="#{TestBean.actionListener}"/> </h:form> </h:body> </html> And this is the simplest possible bean in JSF :- package managedBeans; import java.io.Serializable; import java.util.ArrayList; import java.util.List; import javax.annotation.PostConstruct; import javax.faces.bean.ManagedBean; import javax.faces.bean.ViewScoped; @ManagedBean(name="TestBean") @ViewScoped public class TestBean implements Serializable { private List<String> listItems; public List<String> getListItems() { return listItems; } public void setListItems(List<String> listItems) { this.listItems = listItems; } public TestBean() { } @PostConstruct public void init(){ System.out.println("Post Construct fired!"); listItems = new ArrayList<String>(); listItems.add("Mango"); listItems.add("Apple"); listItems.add("Banana"); } public void actionListener(){ System.out.println("Action Listener fired!"); } } Do you see any behaviour that should cause postconstruct callback to fire each time? I think JSF 2.0 is highly unstable. If it has to fire PostConstruct each and every time what purpose does @ViewScoped serve. Why not to use @RequestScoped only? I thought i have made some mistake in my application. But when i created this simplest possible in JSF, i still get this error. Am i not understanding the scopes of JSF? or are they not testing it properly? Further, if you remove c:forEach and replace it with ui:repeat, then it works fine. Waiting for replies to confirm whether it is bug or it is intentional to stop the programmers from using jstl?

    I'm creating elements (level 1) dynamically which in turn create elements (level 2) themselves. However, the children of level 2 elements have "body" as their parent. In the HTML code below, the content if spotAd2 is created by my function createNode(). It's a Google Ad Sense tag. However, the Google Ad Sense tag create elements that went directly under "body". I need them to by under spotAd2. function createNode( t, // type. tn, // if type is element, tag name. a, // if type is element, attributes. v, // node value or text content p, // parent f ) // whether to make dist the first child or not. { n = null; switch( t ) { case "element": n = document.createElement( tn ); if( a ) { for( k in a ) { n.setAttribute( k, a[ k ] ); } } break; case "text": case "cdata_section": case "comment": n = document.createTextNode(v); break; } if ( p ) { if( f ) { p.insertBefore( n, p.firstChild ); } else { p.appendChild( n ); } } return n; } spotAd2 = document.getElementById("spotAd2"); n1 = createNode("element", "div", {"id":"tnDiv1"}, "\n" , null, true); n2 = createNode("element", "script", {"type":"text\/javascript"}, "\n" , n1, false); n3 = createNode("comment", "", null, "\n" + "google_ad_client = \"pub-0321943928525350\";\n" + "/* 728x90 (main top) */\n" + "google_ad_slot = \"2783893649\";\n" + "google_ad_width = 728;\n" + "google_ad_height = 90;\n" + "//\n" , n2, false); n4 = createNode("element", "script", {"type":"text\/javascript","src":"http:\/\/pagead2.googlesyndication.com\/pagead\/show_ads.js"}, "\n" , n1, false); --- Result: <body> <table cellspacing="2" cellpadding="2" border="1"> <tbody><tr> <td>Oel ngati kemeie</td> <td>Kamakto niwin</td> </tr> <tr> <td>The ad:</td> <td> <div id="spotAd2"> <!-- Created by createNode() --> <div id="tnDiv1"> <script type="text/javascript"> google_ad_client = "pub-0321943928525350"; /* 728x90 (main top) */ google_ad_slot = "2783893649"; google_ad_width = 728; google_ad_height = 90; </script> <script type="text/javascript" src="http://pagead2.googlesyndication.com/pagead/show_ads.js"></script> </div> <!-- Created by createNode() --> </div> </td> </tr> <tr> <td>txopu ra'a tsi, tsamsiyu</td> <td>teyrakup skxawng</td> </tr> </tbody></table> <!-- Created by adsense tag, need these to be under tnDiv1 --> <script src="http://pagead2.googlesyndication.com/pagead/expansion_embed.js"></script> <script src="http://googleads.g.doubleclick.net/pagead/test_domain.js"></script> <script>google_protectAndRun("ads_core.google_render_ad", google_handleError, google_render_ad);</script> <ins style="border: medium none ; margin: 0pt; padding: 0pt; display: inline-table; height: 90px; position: relative; visibility: visible; width: 728px;"> <ins style="border: medium none ; margin: 0pt; padding: 0pt; display: block; height: 90px; position: relative; visibility: visible; width: 728px;"> <iframe width="728" scrolling="no" height="90" frameborder="0" vspace="0" style="left: 0pt; position: absolute; top: 0pt;" src="http://googleads.g.doubleclick.net/pagead/ads?client=ca-pub-0321943928525350&amp;output=html&amp;h=90&amp;slotname=2783893649&amp;w=728&amp;lmt=1273708979&amp;flash=10.0.45&amp;url=http%3A%2F%2Fkenshin.katanatechworks.com%2Ftest%2FadsBrowserSide.php&amp;dt=1273708980294&amp;shv=r20100422&amp;correlator=1273708980298&amp;frm=0&amp;ga_vid=695691836.1273708981&amp;ga_sid=1273708981&amp;ga_hid=1961182006&amp;ga_fc=0&amp;u_tz=480&amp;u_his=2&amp;u_java=1&amp;u_h=1080&amp;u_w=1920&amp;u_ah=1052&amp;u_aw=1920&amp;u_cd=24&amp;u_nplug=5&amp;u_nmime=38&amp;biw=1394&amp;bih=324&amp;fu=0&amp;ifi=1&amp;dtd=955&amp;xpc=Jl67G4xiq6&amp;p=http%3A//kenshin.katanatechworks.com" name="google_ads_frame" marginwidth="0" marginheight="0" id="google_ads_frame1" hspace="0" allowtransparency="true"> </iframe> </ins> </ins> <!-- Created by adsense tag, need these to be under tnDiv1 --> </body>

  • How to schedule dynamic function with cron job?

    - by iBrazilian2
    I want to know how I can schedule a dynamic(auto populated data) function to auto run everyday at saved time? Let's say I have a form that once the button is clicked it sends the data to the function, which the posts the data. I simply want to automate that so that I don't have to press the button. <ul> <?php foreach($Class->retrieveData as $data) { <form method="post" action=""> <li> <input type="hidden" name="name">'.$data['name'].'<br/> <input type="hidden" name="description">'.$data['description'].'<br/> <input type="submit" name="post_data" value="Post"> </li> </form> } ?> </ul> Now, the form will pass the data to the function. if(isset($_POST['post_data'])) // if post_data button is clicked then it runs myFunction() { myFunction(); } myFunction() { $name = $_POST['name']; $description = $_POST['description']; } I tried doing the following but the problem is that Cron Job can only run the whole .php file, and I am retrieving the saved time to run from MySQL. foreach($Class->getTime() as $timeData) { $timeHour = $timeData['timeHour']; $timeMinute = $timeData['timeMinute']; $hourMin = date('H:i'); $timeData = ''.$timeHour.':'.$timeMinute.''; if($hourMin == $timeData) { run myFunction. } } $hourMin is the current hour:minute which is being matched against a saved time to auto run from Mysql. So if $hourMin == $timeData then the function will run. How can I run Cron Job to auto run myFunction() if the $hourMin equals $timeData? So... List 1 = is to be runned at 10am List 2 = is to be runned at 12pm List 3 = is to be runned at 2pm The 10am, 12pm, 2pm is the $timeHour and $timeMinute that is retrieved from MySQL but based on each list id's. EDIT @randomSeed, 1) I can schedule cron jobs. 2) $name and $description will all be arrays, so the following is what I am trying to accomplish. $name = array( 'Jon', 'Steven', 'Carter' ); $description = array( 'Jon is a great person.', 'Steven has an outgoing character.', 'Carter is a horrible person.' ); I want to parse the first arrays from both $name and $description if the scheduled time is correct. In database I have the following postDataTime table +----+---------+----------+------------+--------+ | iD | timeDay | timeHour | timeMinute | postiD | +--------------------------------------+--------+ | 1 | * | 9 | 0 | 21 | |----|---------|----------|------------|--------| | 2 | * | 10 | 30 | 22 | |----|---------|----------|------------|--------| | 3 | * | 11 | 0 | 23 | +----|---------+----------+------------+--------+ iD = auto incremented on upload. timeDay = * is everyday (cron job style) timeHour = Hour of the day to run the script timeMinute = minute of the hour to run script postiD = this is the id of the post that is located in another table (n+1 relationship) If it's difficult to understand.. if(time() == 10:30(time from MySQL postiD = 22)) { // run myFunction with the data that is retrieved for that time ex: $postiD = '22'; $name = 'Steven'; $description = 'Steven has an outgoing character.'; // the above is what will be in the $_POST from the form and will be // sent to the myFunction() } I simply want to schedule everything according to the time that is saved to MySQL as I showed at the very top(postDataTime table). (I'd show what I have tried, but I have searched for countless hours for an example of what I am trying to accomplish but I cannot find anything and what I tried doesn't work.). I thought I could use the exec() function but from what it seems that does not allow me to run functions, otherwise I would do the following.. $time = '10:30'; if($time == time()) { exec(myFunction()); }
