  • show-hide image onmouseover

    - by butters
    I have 3 images on top of each other. The first one is a normal .jpg image, the second a greyscale version and the 3rd is some kind of effect i add with a transparent .png Now what i want is that, if i move the mouse over those images, the greyscale image is hidden or replaced by another image and afterwards visible again. The problem here is that i am a js noob, so it's kind of hard for me to find a solution ^^ my code looks something like this: <html> <head> <style type="text/css"> <!-- ul li{ display: inline-table; } .frame{ position: relative; height: 110px; width: 110px; } .frame div{ position: absolute; top:0px; left:0px; } .effect{ background:url(images/effect.png) no-repeat; height:110px; width: 110px; } .image{ height:100px; width:100px; border: 1px solid red; margin:4px; } .greyscale{ height:100px; width:100px; border: 1px solid red; margin:4px; } --> </style> </head> <body> <ul> <li> <div class="frame"> <div class="image"><img src="images/pic1.jpg" height="100" width="100"></div> <div class="greyscale"><img src="images/grey1.jpg" height="100" width="100"></div> <div class="effect">qwert</div> </div> </li> <li> <div class="frame"> <div class="image"><img src="images/pic2.jpg" height="100" width="100"></div> <div class="greyscale"><img src="images/grey2.jpg" height="100" width="100"></div> <div class="effect">qewrt</div> </div> </li> </ul> </body> </html> </code></pre> would be super-awesome if someone can help me out :)

  • dynamic button in jsp

    - by kawtousse
    hi everyone, in my jsp i have a table constructed dynamically like the following: retour.append("<tr>"); try { s= HibernateUtil.currentSession(); tx=s.beginTransaction(); Query query = s.createQuery(HQL_QUERY); for(Iterator it=query.iterate();it.hasNext();) { if(it.hasNext()){ Dailytimesheet object=(Dailytimesheet)it.next(); retour.append("<td>" +object.getActivity() +"</td>"); retour.append("<td>" +object.getProjectCode() + "</td>"); retour.append("<td>" +object.getWAName() + "</td>"); retour.append("<td>" +object.getTaskCode() +"</td>"); retour.append("<td>" +object.getTimeFrom() +"</td>"); retour.append("<td>" +object.getTimeSpent() + "</td>"); retour.append("<td>" +object.getPercentTaskComplete() + "</td>"); if (droitdaccess) { retour.append(""); retour.append(""); retour.append(""); retour.append("<td bordercolor=#FFFFFF>"); retour.append("<input type=\"hidden\" id=\"id_"+nomTab+"_"+compteur+"\" value=\""+object.getIdDailyTimeSheet()+"\"/>"); retour.append("<img src=\"icon_delete.gif\" onClick=\"deletearowById('id_"+nomTab+"_"+compteur+"')\" style=\"cursor:pointer\" name=\"action\" value=\"deleting\" />"); retour.append("</td>"); } } compteur++; retour.append("</tr>"); } //terminer la table. retour.append ("</table>"); next to the table i want to display a button named send in order to send the table content. I do not really want to dispaly this button where the table is empty. So at least if the table is populated by nly one record i want that button being displayed. How should i deal in this case. Thanks.

  • dojo layout tutorial dor version 1.7 doesn't work for 1.7.2

    - by Sheena
    This is sortof a continuation to dojo1.7 layout acting screwy. So I made some working widgets and tested them out, i then tried altering my work using the tutorial at http://dojotoolkit.org/documentation/tutorials/1.7/dijit_layout/ to make the layout nice. After failing at that in many interesting ways (thus my last question) I started on a new path. My plan is now to implement the layout tutorial example and then stick in my widgets. For some reason even following the tutorial wont work... everything loads then disappears and I'm left with a blank browser window. Any ideas? It just struck me that it could be browser compatibility issues, I'm working on Firefox 13.0.1. As far as I know Dojo is supposed to be compatible with this... anyway, have some code: HTML: <body class="claro"> <div id="appLayout" class="demoLayout" data-dojo-type="dijit.layout.BorderContainer" data-dojo-props="design: 'headline'"> <div class="centerPanel" data-dojo-type="dijit.layout.ContentPane" data-dojo-props="region: 'center'"> <div> <h4>Group 1 Content</h4> <p>stuff</p> </div> <div> <h4>Group 2 Content</h4> </div> <div> <h4>Group 3 Content</h4> </div> </div> <div class="edgePanel" data-dojo-type="dijit.layout.ContentPane" data-dojo-props="region: 'top'"> Header content (top) </div> <div id="leftCol" class="edgePanel" data-dojo-type="dijit.layout.ContentPane" data-dojo-props="region: 'left', splitter: true"> Sidebar content (left) </div> </div> </body> Dojo Configuration: var dojoConfig = { baseUrl: "${request.static_url('mega:static/js')}", //this is in a mako template tlmSiblingOfDojo: false, packages: [ { name: "dojo", location: "libs/dojo" }, { name: "dijit", location: "libs/dijit" }, { name: "dojox", location: "libs/dojox" }, ], parseOnLoad: true, has: { "dojo-firebug": true, "dojo-debug-messages": true }, async: true }; other js stuff: require(["dijit/layout/BorderContainer", "dijit/layout/TabContainer", "dijit/layout/ContentPane", "dojo/parser"]); css: html, body { height: 100%; margin: 0; overflow: hidden; padding: 0; } #appLayout { height: 100%; } #leftCol { width: 14em; }

  • How to obtain a pointer out of a C++ vtable?

    - by Josh Haberman
    Say you have a C++ class like: class Foo { public: virtual ~Foo() {} virtual DoSomething() = 0; }; The C++ compiler translates a call into a vtable lookup: Foo* foo; // Translated by C++ to: // foo->vtable->DoSomething(foo); foo->DoSomething(); Suppose I was writing a JIT compiler and I wanted to obtain the address of the DoSomething() function for a particular instance of class Foo, so I can generate code that jumps to it directly instead of doing a table lookup and an indirect branch. My questions are: Is there any standard C++ way to do this (I'm almost sure the answer is no, but wanted to ask for the sake of completeness). Is there any remotely compiler-independent way of doing this, like a library someone has implemented that provides an API for accessing a vtable? I'm open to completely hacks, if they will work. For example, if I created my own derived class and could determine the address of its DoSomething method, I could assume that the vtable is the first (hidden) member of Foo and search through its vtable until I find my pointer value. However, I don't know a way of getting this address: if I write &DerivedFoo::DoSomething I get a pointer-to-member, which is something totally different. Maybe I could turn the pointer-to-member into the vtable offset. When I compile the following: class Foo { public: virtual ~Foo() {} virtual void DoSomething() = 0; }; void foo(Foo *f, void (Foo::*member)()) { (f->*member)(); } On GCC/x86-64, I get this assembly output: Disassembly of section .text: 0000000000000000 <_Z3fooP3FooMS_FvvE>: 0: 40 f6 c6 01 test sil,0x1 4: 48 89 74 24 e8 mov QWORD PTR [rsp-0x18],rsi 9: 48 89 54 24 f0 mov QWORD PTR [rsp-0x10],rdx e: 74 10 je 20 <_Z3fooP3FooMS_FvvE+0x20> 10: 48 01 d7 add rdi,rdx 13: 48 8b 07 mov rax,QWORD PTR [rdi] 16: 48 8b 74 30 ff mov rsi,QWORD PTR [rax+rsi*1-0x1] 1b: ff e6 jmp rsi 1d: 0f 1f 00 nop DWORD PTR [rax] 20: 48 01 d7 add rdi,rdx 23: ff e6 jmp rsi I don't fully understand what's going on here, but if I could reverse-engineer this or use an ABI spec I could generate a fragment like the above for each separate platform, as a way of obtaining a pointer out of a vtable.

  • usercontrol hosted in IE renders as a textbox

    - by coxymla
    On my ongoing saga to mirror the hosting of a legacy app on a clean box, I've hit my next snag. One page relies on a big .NET UserControl that on the new machine renders only as a big, greyed out textarea (greyed out vertical scrollbar on the right hand edge. Inspecting the source shows the expected object tag.) This is particularly tricky because nobody seems to know much about hosted UserControls and all the discussions data back to 2002-2004. The page is quite simple: <%@ Page language="c#" Codebehind="DataExport.aspx.cs" AutoEventWireup="false" Inherits="yyyyy.Web.DataExport" %> <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN" > <html> <head> <title>DataExport</title> <link rel="Configuration" href="/xxxxx/yyyyy/DataExport.config"> </head> <body style="margin:0px;padding:0px;overflow:hidden"> <OBJECT id="DataExport" style="WIDTH: 100%; HEIGHT: 100%; position:absolute; left: 0px; top:0px" classid="yyyyy.Common.dll#yyyyy.Controls.DataExport" VIEWASTEXT> </OBJECT> </body> </html> The config file referenced: <?xml version="1.0" encoding="utf-8" ?> <configuration> <configSections> <sectionGroup name="yyyyy"> <section name="dataExport" type="yyyyy.Controls.DataExportSectionHandler,yyyyy.Common" /> </sectionGroup> </configSections> <yyyyy> <dataExport> <layoutFile>http://vm2/xxxxx/yyyyy/layout.xml</layoutFile> <webServiceUrl>http://vm2/xxxxx/yyyyy/services/yyyyy.asmx</webServiceUrl> </dataExport> </yyyyy> </configuration> What I've checked: Security permissions should be OK, the site is trusted and adding a URL exception to grant FullTrust doesn't change anything. Config file is acessible over the web, layout.xml is accessible, ASMX shows the expected command list Machine.config grants GET permission for the usercontrol.config file. What perhaps looks fishy to me: The DataExport UserControl references Aspose.Excel to generate the spreadsheets it exports. When I navigate to the page and get a blank textbox, then run gacutil /ldl, nothing is in the local download cache. On the working machine, running the same command after viewing the page shows a laundry list of DLLs including the control DLL and the Aspose DLL.

  • JSON and WebOS simple example?

    - by user558361
    I have been following this tutorial http://tinyurl.com/327p325 which has been GREAT up until this point where I can't get his code to work. I get the list working with static items but I can't get it to work with the json items. I've tried to simplify it with what I really want it to do to try and debug what is wrong (also if someone could please tell me how to view the Mojo log that would be awesome) In the tutorial he has to use the yahoo service to convert the site into json data, while the site I want to interact with already has json data generated so this is what I have PageAssistant.prototype.setup = function() { this.myListModel = { items : [] }; this.myListAttr = { itemTemplate: "page/itemTemplate", renderLimit: 20, }; this.controller.setupWidget("MyList",this.myListAttr,this.myListModel); this.controller.setupWidget("search_divSpinner", { spinnerSize : "large" }, { spinning: true } ); }; PageAssistant.prototype.activate = function(event) { this.getData(); }; PageAssistant.prototype.getData = function () { // the spinner doesn't show up at all $("search_divScrim").show(); var url = "http://www.website.com/.json"; var request = new Ajax.Request(url, { method: 'get', asynchronous: true, evalJSON: "false", onSuccess: this.parseResult.bind(this), on0: function (ajaxResponse) { // connection failed, typically because the server is overloaded or has gone down since the page loaded Mojo.Log.error("Connection failed"); }, onFailure: function(response) { // Request failed (404, that sort of thing) Mojo.Log.error("Request failed"); }, onException: function(request, ex) { // An exception was thrown Mojo.Log.error("Exception"); }, }); } PageAssistant.prototype.parseResult = function (transport){ var newData = []; var theStuff=transport.responseText; try { var json = theStuff.evalJSON(); } catch(e) { Mojo.Log.error(e); } // this is where I believe I am wrong for (j=0;j < json.data.count;j++) { var thread=json.data.children[j]; newData[j] = { title: thread.data.author }; } this.myListModel["items"] = newData; this.controller.modelChanged(this.myListModel , this); $("search_divScrim").hide(); } So where I commented that I believe I am wrong I am just trying to get the title out of this json data { kind: Listing data: { children: [ { kind: food data: { author: Foodmaster hidden: false title: You should eat this } }, // then it repeats with the kind: and data Anyone see where I went wrong? I would like to know how to view the log as I have log events but can't figure out where to look to see if any of them are being thrown.

  • Stuck with jQuery thumbnail gallery behavior

    - by Vitor
    Hi everyone, I'm trying to create a simple thumbnail viewer with jQuery. Here goes the code: $(function(){ $("ul.thumbnails li").click(function(e){ var imgAlt = $(this).find('img').attr("alt"); //Get Alt Tag of Image var imgTitle = $(this).find('a').attr("href"); //Get Main Image URL $("img.featured").attr({ src: imgTitle , alt: imgAlt}); //Switch the main image (URL + alt tag) }); <div class="image-gallery"> <img class="featured" src="big.jpg"> <ul class="thumbnails"> <li id="thumb01"> <a href="big.jpg"><img src="small.jpg"></a> </li> <li id="thumb02"> <a href="big.jpg"><img src="small.jpg"></a> </li> <li id="thumb03"> <a href="big.jpg"><img src="small.jpg"></a> </li> </ul> .thumbnails li { margin: 0; padding: 5px 5px 0 5px; list-style: none; float: left; overflow: hidden; } thumbnails li img { width: 50px; height: 50px; margin: 0; padding: 0; float: left; } If i click the thumbnail, the browser goes straight to the full image instead of just changing the img src with jQuery. But I if i click somewhere inside the <li> it works. I know this must be simple, but I don't know where I'm going wrong. I've tried studying other galleries, like http://www.sohtanaka.com/web-design/examples/image-rotator/ , but couldn't find what I'm missing. I could really use some help from you guys :)

  • ASP.net: Radio Button Not Maintaining Selection After Postback, Inside DIV/Thickbox

    - by jlrolin
    I have a set of radio buttons inside a hidden DIV. <div id="reports" style="display:none;"> <center> <br /> <table cellpadding="4" cellspacing="0"> <tr> <td class="label"> Report Type::&nbsp; </td> <td class="value"> <asp:RadioButton ID="rbReportTypeCust" runat="server" Text="By Customer" Enabled="True" Checked="True" GroupName="rbType" />&nbsp;<asp:RadioButton ID="rbReportTypeProg" runat="server" Text="By Program" Enabled="True" GroupName="rbType" /> </td> </tr> <tr> <td class="label"> Customer:&nbsp; </td> <td class="value"> <asp:DropDownList ID="ddlCustomer" runat="server" /> </td> </tr> <tr> <td class="label"> Program Group::&nbsp; </td> <td class="value"> <asp:DropDownList ID="ddlProgramGroups" runat="server" /> </td> </tr> </table> <br /> <asp:Button ID="btnSubmit" runat="server" Text="Submit" OnClientClick="doPostBack(this);" /> </center> </div> The DIV is displayed using Thickbox as a modal popup. The doPostback javascript function posts the button click back, and hits btnSubmit_Click where a report is then generated. If I see if a radio button is checked, it's always rbReportTypeCust.checked = True, never the rbReportTypeProg.checked = True even if I click it. Any suggestions?

  • XmlHttpRequest bug?

    - by valdo
    Hello all. I'm writing a program that among other things needs to download a file given its URL. I'm too lazy to implement the Http/Https protocols manually, so that I needed some library/object/function that'll do the job. Critical requirement: The download must be asynchronous. That is, the thread that issued the download must be able to do something else "while" downloading the file, plus the download must be able to be aborted anytime without any barbaric side effects (such as internal call to TerminateThread). Nice-to-have requirements: Should be able to download the file "into memory". Means - read the contents of the file as they arrive, not necessarily save it into some "file system" file. It'd be nice to have some convenient Win32 progress notification mechanism (waitable event, semahpore, completion port, etc.), rather than just periodically polling the download status. I've chosen the XmlHttpRequest COM object to do the work. It seemed to work fine enough, plus it supported asynchronous mode. However I noticed that after some period it just stops working. That is, after several successful file downloads it stops downloading anything. I periodically poll it to get its status, it reports "in-progress", but nothing actually happens, and there's no network activity. Moreover, when the same process creates another instance of XmlHttpRequest object to perform new downloads - the effect is the same. The object reports "in progress", whereas it doesn't even try to connect to the server (according to network sniffers and system TCP state). The only way to make this object work back is to restart the process. This makes me suspect that there's a sort of a bug (sorry, I meant undocumented feature) in the object. Also it's not a bug at the level of an individual object, since the problem persists when the object is destroyed and another one is created. It's probably some global state of the DLL that implements this object. Does anyone know something about this? Is this a known bug? I'm pretty sure there's no chance that I have another bug in my code, because of which it seems to me to be the bug is in the XmlHttpRequest. I've done enoughtests and spent time with the debugger to conclude without reasonable doubt that it's just the object stops working. BTW, while the object should work, I do all the waiting via MsgWaitXXXX API calls. So that if this object needs the message loop to work properly (for instance, it may create a hidden notification window and bind it to a socket via WSAAsyncSelect) - I give it the opportunity.

  • Phonegap web view thinks device screen taller than it is - results in offscreen tabbar

    - by Stin
    I have a jQTouch application loaded via server, so all I need to do is display the webpage full screen in PhoneGap for a faux-Native app. Unfortunatley each solution I've tried in PhoneGap has an issue: it thinks the screen size is taller than it is. This resuls in the tabbar that is pinned to the bottom being permantly offscreen and there fore unusable. You should be able to recreate this with my code below and going to the iTabbar online demo. Any thoughts on how to correct this issue? For background, going to the app page in iOS safari works fine, as well as saving the page to the home screen. In both cases the webview stops at the bottom of the screen and the tabbar is therefore viewable. Also, I'm using build.phonegap.com to compile (I'm not compiling locally) I've tried two methods: load the childBrowser plugin and call up the page (with navbar hidden via options) set the following config.xml parameter to prevent phonegap from switching to Safari, and then just load the link (preferable as it's cleaner in my mind. I've pasted my index.html and config.xml below) Details on the config.xml paramater: Open all links in WebView stay-in-webview with values true or false example: <preference name="stay-in-webview" value="true" /> if set to true, all links (even with target set to blank) will open in the app's webview only use this preference if you want pages from your server to take over your entire app default is false (Source: https://build.phonegap.com/docs/config-xml) my index.html: <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd"> <html> <head> <meta http-equiv="Content-type" content="text/html;charset=utf-8"> <title>MyApp</title> <script src="phonegap.js"></script> </head> <body> <p><a href="http://www.itabbar.com/itabbar/demo.html#home">Launch iTabbar</a></p> </body> </html> my config.xml: <?xml version="1.0" encoding="UTF-8" ?> <widget xmlns = "http://www.w3.org/ns/widgets" xmlns:gap = "http://phonegap.com/ns/1.0" id = "com.phonegap.myapp" versionCode="10" version = "1.0.0"> <!-- versionCode is optional and Android only --> <name>MyApp</name> <description> My app is... </description> <author href="https://myurl.com" email="[email protected]"> me </author> <preference name="stay-in-webview" value="true" /> </widget>

  • jquery xml slideshow using ajax

    - by Codemaster Snake
    Hi all, I am trying to create a JQuery based slider using ajax to load images url from a xml file and then creating a html li list dynamically. Till now I am able to append and create DOM structure using Jquery. But I am not able to access the dynamically created list. I have also tried custom events using bind but not able to successfully implement it. Following is my jquery plugin code: (function($){ $.fn.genie = function(options) { var genie_dom = "<div class='genie_wrapper'><ul class='genie'></ul></div>"; var o, base; var genie_styles = "<style>.genie_wrapper{overflow:hidden}.genie{position: relative;margin:0;padding:0}.genie li {position: absolute;margin:0;padding:0}</style>"; var defaults = { width : '960px', height : '300px', background_color : '#000000', xml : 'genie.xml', speed : 1000, pause: 1000 }; base = $(this); o = $.extend(defaults, options); return this.each(function() { create_elements(); }); function create_elements() { $(base).html(genie_dom); $('head').append(genie_styles); $('.genie_wrapper').css({'background-color' : o.background_color, width : o.width, height: '300px', overflow: ''}); $.ajax({ type: "GET", url: o.xml, dataType: "xml", success: function(xml) { var slides = $(xml).find('slide'); var count = 0; $(slides).each(function(){ $('.genie').append('<li class="slide" id="slide'+count+'"><img src="' + $(this).text() + '" /></li>'); $('.genie li:last').css({'z-index' : count}); count++; }); } }); } } })(jQuery); In my html file: There is only one empty div to which I am calling my plugin like $(document).ready(function() { $('.slideshow').genie(); }); I have also tried using following everywhere in JS: $(".slide").bind("start_animation", function(e){ $(this).fadeOut(1000); alert($(this).html()); }); $(".slide").trigger("start_animation"); I want to animate li list using animate function, Can anyone please tell me how to implement it... It would be of great help... Regards, Neeraj Kumar EDIT: Can Anyone help me out please????

  • Measure width() with jQuery after DOM refresh

    - by o_O Tync
    My script dynamically creates a <ul> width left-floating <li>s inside: it's a paginator. Afterwards, the script measures width of all <li>s and summs them up. The problem is that after the nodes are injected into the document — the browser refreshed DOM and applies CSS styles which takes a while. It has a negative effect on my script: when these operations are not complete before I measure the width — my script gets a wrong value. If I perform the measure in a second — everything is ok. The thing I'm looking for is a way to detect the moment when the <ul> is fully drawn, styles applied and the width has stabilizes. Or at least a way to detect every dimensions changes. Of course I can use setTimeout(..., 100) but it's ugly and I guess — not a solution at all. If there's a way to detect width stabilization — I would do the measuring right after it to get the correct values. HTML code generated by the DOM <div> <ul> <li><a href="...">1</a></li> <li><a href="...">2</a></li> .... </ul> </div> P.S. Why I need this. My paginator's left-floating <li> items tend to move to the next line when the <ul> tries to become wider than the page itself. Even though most of <li>s are invisible because of parent <div>'s width restriction: div { width: 500px; overflow: hidden; } div ul { width: 100%; white-space: nowrap; } div ul li { display: block; float: left; } they still go down unless I specify the actual summed width of the <ul> with the script.

  • Creating AST for shared and local variables

    - by Rizwan Abbasi
    Here is my grammar grammar simulator; options { language = Java; output = AST; ASTLabelType=CommonTree; } //imaginary tokens tokens{ SHARED; LOCALS; BOOL; RANGE; ARRAY; } parse : declaration+ ; declaration :variables ; variables : locals ; locals : (bool | range | array) ; bool :ID 'in' '[' ID ',' ID ']' ('init' ID)? -> ^(BOOL ID ID ID ID?) ; range : ID 'in' '[' INT '..'

Variables (bool, range or array) can be of two abstract types 1. locals (each object will have it's own variable) 2. shared (think of static in java, same for all object) Now the requirements are changed. I want the user to input like this NEW INPUT domains: upDown [up,down] possibleStates [0-7] booleans [true,false] locals: pc in possibleStates init 0 flag in upDown init down flag1 in upDown init down map in array of booleans init false shared: pcs in possibleStates init 0 flag in upDown init down flag1 in upDown init down maps in array of booleans init false Again, all the variables can be of two types (of any domain sepecified) 1. Local 2. Shared In Domains: upDown [up,down] possibleStates [0-7] upDown, up, down and possibleStates are of type ID (ID is defined in my above grammar), 0 and 7 are of type INT Can any body help me how to convert my current grammar to meet new specifications.

  • I have a bunch of images being shown on click via JQuery - any easy way to animate this?

    - by Cenk
    This is the (quite simple) JS code I'm using: $(document).ready(function() { $(".button-list .next").click(function() { project = $(this).parents().filter(".projektweb").eq(0); currentimg = project.find(".images-list li.current"); nextimg = currentimg.next(); firstimg = project.find(".images-list li:first"); currentimg.removeClass("current"); if (nextimg.is("li")) nextimg.addClass("current"); else firstimg.addClass("current"); return false; }); $(".button-list .prev").click(function() { project = $(this).parents().filter(".projektweb").eq(0); currentimg = project.find(".images-list li.current"); previmg = currentimg.prev(); lastimg = project.find(".images-list li:last"); currentimg.removeClass("current"); if (previmg.is("li")) previmg.addClass("current"); else lastimg.addClass("current"); return false; }); }); And this is how the HTML code for the image list looks like: <ul class="images-list"> <li class="current"><img src="img/1.jpg" alt="" /></li> <li><img src="img/1b.jpg" alt="" /></li> </ul> <ul class="button-list"> <li><a class="button prev" href="#">?</a></li> <li><a class="button next" href="#">?</a></li></ul> The CSS: .images-list { height: 460px; list-style-type:none; float:left; width: 460px; overflow:hidden; position:relative; } .images-list img { height: 460px; width: 460px; display:block; } .images-list li { display:none; } .images-list li.current { display:block; } What I'd like to do is animate the images as they come and go - right now they just appear, which is OK but a bit more eye-candy would be nice. Can anyone help me out here? It it even possible to do it this way? Thanks!!

  • Flexslider position of previous and next slides

    - by TJ15
    I am using the basic flexslider, I wantto display some of the previous and next , so if slide 2 is showing you will see part of slide 1 to the left and part of slide 3 to the right. <!DOCTYPE html> <head> <link rel="stylesheet" href="flexslider.css" type="text/css"> <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.6.2/jquery.min.js"></script> <style> .container {overflow: hidden; width: 100%} .flexslider {max-width: 500px; width: 500px; margin: 0 auto} .content {background: #f2f2f2; max-width: 500px; display: block; margin: 0 auto} .flex-viewport {overflow: visible !important} </style> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>Untitled Document</title> </head> <body> <div class="container"> <div class="flexslider"> <ul class="slides"> <li><img src="785.jpg" /></li> <li><img src="785.jpg" /></li> <li><img src="785.jpg" /></li> <li><img src="785.jpg" /></li> </ul> </div> </div> <script src="jquery.flexslider.js"></script> <script> jQuery(document).ready(function($) { // You can use the locally-scoped $ in here as an alias to jQuery. $(window).load(function() { $('.flexslider').flexslider(); }); }); </script> </body> </html> I have reduced the image to 70% and positioned it in the middle of the page. I want to have the next and previous slides visible on either side of the main pic but no idea where to make the appropriate changes (I assume in the js file). I thought this was a margin issue but setting this to 0 in styles makes no difference. Has anyone done this and can provide some advice?

  • Rails has-and-belongs-to-many form question

    - by swilliams
    Sorry for the semi-generic title, but I'm still pretty new at rails and couldn't think of a succinct way to put the question. I have a basic habtm model setup: a Project has many Resources and a Resource can have many Projects. I have the database and models setup properly, and can do everything I need to via the console, but I'm having trouble translating it all into the view. On the show view for the Project, I want to be able to create a Resource and automatically assign it to the current Project. Here's my basic html: <p> <b>Name:</b> <%=h @project.name %> </p> <h2>Equipment</h2> <ul> <% @project.resources.each do |r| %> <li><%=h r.name %></li> <% end %> </ul> <h2>Add A Resource</h2> <% form_for(@project) do |f| %> <%= f.error_messages %> <p> Resource Name:<br /> <%= f.text_field :resources %> </p> <p> <%= f.submit 'Create' %> </p> <% end %> Obviously, that form won't work, but I'm at a loss for what to do next. I've searched around for various examples, but haven't found one for what I'm trying to do here. One thing I've thought of was to change the form to be form_for(Resource.new) and include a hidden input of the @project.id. And then when the resource_controller handles the form, check for that id and go from there. That seems like an ugly kludge though.

  • jquery, manipulate content inserted by ajax, without using the callback

    - by Cody
    I am using ajax to insert a series of informational blocks via a loop. The blocks each have a title, and long description in them that is hidden by default. They function like an accordion, only showing one description at a time amongst all of the blocks. The problem is opening the description on the first block. I would REALLY like to do it with javascript right after the loop that is creating them is done. Is it possible to manipulate elements created ofter an ajax call without using the callback? <!-- example code--> <style> .placeholder, .long_description{ display:none;} </style> </head><body> <script> /* yes, this script is in the body, dont know if it matters */ $(document).ready(function() { $(".placeholder").each(function(){ // Use the divs to get the blocks var blockname = $(this).html(); // the contents if the div is the ID for the ajax POST $.post("/service_app/dyn_block",'form='+blockname, function(data){ var divname = '#div_' + blockname; $(divname).after(data); $(this).setupAccrdFnctly(); //not the actual code }); }); /* THIS LINE IS THE PROBLEM LINE, is it possible to reference the code ajax inserted */ /* Display the long description in the first dyn_block */ $(".dyn_block").first().find(".long_description").addClass('active').slideDown('fast'); }); </script> <!-- These lines are generated by PHP --> <!-- It is POSSIBLE to display the dyn_blocks --> <!-- here but I would really rather not --> <div id="div_servicetype" class="placeholder">servicetype</div> <div id="div_custtype" class="placeholder">custtype</div> <div id="div_custinfo" class="placeholder">custinfo</div> <div id="div_businfo" class="placeholder">businfo</div> </body>

  • Hide jQuery Accordion while loading

    - by zac
    I am testing a site build with a slow connection and I noticed the jQuery Accordion stays expanded for a long time, until the rest of the site is loaded, and then finally collapses. Not very pretty. I was wondering how I could keep it collapsed through the loading process and only expand when clicked. I am working with the standalone 1.6 version of the accordion plugin. The basic structure : <div class="sidebar"> <ul id="navigation" class="ui-accordion-container"> <li><a class="head" href="#">1</a> <ul class="sub"> <li><a href="#">1a</a></li> <li><a href="#">2a</a></li> </ul> </li> </ul> </div> and the script jQuery().ready(function(){ jQuery('#navigation').accordion({ active: 'false', header: '.head', navigation: true, animated: 'easeslide', collapsible: true }); }); I tried to hide the elements in the CSS to keep them from appearing while loading but all that achieved is in having them always hidden. Maybe the problem is in the CSS I have a background image in each of the sub menus: #navigation{ margin:0px; margin-left: 10px; padding:0px; text-indent:0px; font-size: 1.1em; width:200px; text-transform: uppercase; padding-bottom: 30px; } #navigation ul{ border-width:0px; margin:0px; padding:0px; text-indent:0px; } #navigation li{ list-style:none outside none; } #navigation li ul{ height:185px; overflow:auto; } #navigation li ul.sub{ background:url('../images/sub.jpg') no-repeat; dispaly: block; } #navigation li li a{ color:#000000; display:block; text-indent:20px; text-decoration: none; padding: 6px 0; } #navigation li li a:hover{ background-color:#FFFF99; color:#FF0000; } Thanks in advance for any advice on how to have this thing run a little smoother and having the accordion always collapsed. -edit - I forgot to mention that I am also hoping for a solution that will allow the nav to still be accessible for those without javscript.

  • jQuery: form input values turns up undefined

    - by Seerumi
    Having problem with this bit of code qith jQuery. it should pick the values from current form and then submit them, but when I try to get them with jQuery they always turn up undefined. I know the SQL results are fine since they show correctly in HTML table, so it must be my inferior javascript skills. New with jQuery and I'm at loss :( PHP/HTML: echo "<table>\n" while ($row = odbc_fetch_array($query)) { echo "<form class='catForm'>\n"; echo "<input type=hidden class='catID' name='catID' value='".$row['running_id']."'/>\n"; echo "<tr>\n"; echo "<td>".$row['running_id']."</td>\n"; echo "<td>".$row['site_id']."</td>\n"; echo "<td>".$row['main_category']."</td>\n"; echo "<td>".$row['map_name']."</td>\n"; echo "<td><input type=textfield class='bCatID' value='".$row['mapping_id']."' size=6/></td>\n"; echo "<td><input type=submit class='saveCat' value='Save'/></td>\n"; echo "<td><input type=submit class='killCat' value='Delete' /></td>\n"; echo "</tr>\n"; echo "</form>\n"; } echo "</table>"; jQuery: $(".catForm").submit(function () { var id = $(this).find('.catID').val(); var bCatID = $(this).find('.bCatID').val(); var dataString = 'id='+id+'&bCatID='+bCatID; $.ajax({ type: "POST", url: 'adminUI/bin/updateSCategories.php', dataType : 'json', data: dataString, success: function(data) { if (data.error == true) $('.failure').html("Error, save failed.").show().fadeOut(2000); if (data.error == false) $('.success').html("Saved succesfully").show().fadeOut(2000); }, error: function(XMLHttpRequest, textStatus, errorThrown) { $('.failure').html("Error, save failed.").show().fadeOut(2000); } }); return false; }); RESULT: id: undefined bCatID: undefined

  • Problem passing variables in php form.

    - by Joshxtothe4
    I have the following php form. I am trying to make it so that when the form is loaded, the values will be assigned the appropriate check- variable. This variable will contain either "checked or "". If it contains checked, the way it is displayed with the html should cause the relevant checkbox to be checked. As it is, the variables do not seem to be being passed. When I echo out $deleted or $notice from within the submitinfo branch, they are blank. Furthermore, nothing is being inserted into the database, and I am not getting any database error. How can I check this? <?php if (isset($_GET["cmd"])) $cmd = $_GET["cmd"]; else if (isset($_POST["cmd"])) $cmd = $_POST["cmd"]; else die("Invalid URL"); if (isset($_GET["pk"])) { $pk = $_GET["pk"]; } if (isset($_POST["deleted"])) { $deleted = $_POST["deleted"]; } if (isset($_POST["notice"])) { $notice = $_POST["notice"]; } $con = mysqli_connect("localhost","user","password", "db"); if (!$con) { echo "Can't connect to MySQL Server. Errorcode: %s\n". mysqli_connect_error(); exit; } $con->set_charset("utf8"); $getformdata = $con->query("select * from STATUS where ARTICLE_NO = '$pk'"); $checkDeleted = ""; $checkNotice = ""; while ($row = mysqli_fetch_assoc($getformdata)) { $checkDeleted = $row['deleted']; $checkNotice = $row['notice']; } if($cmd=="submitinfo") { $statusQuery = "INSERT INTO STATUS VALUES (?, ?)"; if ($statusInfo = $con->prepare($statusQuery)) { $statusInfo->bind_param("ss", $deleted, $notice); $statusInfo->execute(); $statusInfo->close(); echo "true"; } else { echo "false"; } print_r($con->error); } if($cmd=="EditStatusData") { echo "<form name=\"statusForm\" action=\"test.php\" method=\"post\" enctype=\"multipart/form-data\"> <h1>Editing information for auction: ".$pk."</h1> Löschung Ebay: <input type=\"checkbox\" name=\"deleted\" value=\"checked\" ".$checkDeleted." /> <br /> Abmahnung: <input type=\"checkbox\" name=\"notice\" value=\"checked\" ".$checkNotice." /> <br /> <input type=\"hidden\" name=\"cmd\" value=\"submitinfo\" /> <input name=\"Submit\" type=\"submit\" value=\"submit\" /> </form>"; } else { print_r($con->error); }
