  • Showing multiple elements onClick

    - by Nimbuz
    HTML: <ul id="mode"> <li><a href="#tab1">tab1</a> <div class="extra">tada</div> </li> <li><a href="#tab2">tab2</a> <div class="extra">tada</div> </li> </ul> <div id="tab1" class="tab-content" style="display: none">content 1</div> <div id="tab2" class="tab-content" style="display: none">content 2</div> ? jQuery: $(function(){ var mode = $('#mode'); var arrow = $('<span/>', {'class': 'arrow'}); $('li a', mode).bind('click.mytabs', function() { $('li', mode).removeClass('active'); $(this).parent().addClass('active').append(arrow); var a = $(this).attr('href'); $('.tab-content').hide(); $(a).show(); return false; }).filter(':first').triggerHandler('click.mytabs'); // eq(0) works as well }); JSFiddle here: http://jsfiddle.net/wwMJL/ I'd like to also show each li's 'extra' div on click and hide when the tab is inactive, what do I need to change in the code? Thanks!

  • On checkbox checked show radio button

    - by aDameToKillFor
    Hello, I would like to ask for a little help here, since I haven't got any big knowledge in Javascript, nor in jQuery. I need to show 5 radio buttons when a checkbox is checked, the checkboxes represent languages that the user speaks, so for each of the selected, there should appear 5 separate radio buttons for how good they speak it(1 to 5). I tried to do it with jQuery, but I did not manage to get very far away... This is where my checkboxes are created(dynamically): <% for(int i = 0; i < Model.Languages.Count; i++) { %> <input id="applang" name="applang" type="checkbox" value="<%: Model.Languages[i].languageID%>" /> <%: Model.Languages[i].name.ToString() %><br /> <%} %> So, I tried to add this script, but it's not working: <script type="text/javascript"> $("input[@name='applang']").click(function () { $("input[type='radio']").show(); }); I also tried this way - to use this javascript: <script type="text/javascript"> function toggle_visibility(id) { var e = document.getElementById(id); if (e.style.display == 'block') e.style.display = 'none'; else e.style.display = 'block'; } And it works, but it works on already present controls, and I guess I need to create mine dynamically, or maybe not? And I tried to hide a present control with CSS, but then when the script shows it, it is there, only invisible :) Also, I would want to get the name and value of the radio buttons from my database, i.e. Model(this is ASP.NET MVC).. Can someone help me a little bit, please?

  • AJAX Request Erroring

    - by 30secondstosam
    I can not figure out for the life of me why this is erroring - can someone please cast a second pair of eyes over this - it's probably something really stupid, thanks in advance for the help: EDIT Stupidly I was putting the wrong URL in - HOWEVER...

  • Can you do this with Hudson?

    - by damian
    I want to create a hudson job, that takes an id as a parameter. And use that id to calculate the svn-repo path. Where I work you have a svn path for every issue that you resolve. And then all the issues are joined into a single svn-path. What I want to do is to run static code analysis on the partial issues. So I think maybe having an Ant build.xml that I use for every issue, then, parametrize the job with the issue id. I have tried to achieve that but the svn path doesn't replace the parameter. I have tried with #issueId, %issueId%, ${issueId} and ${env.issueId} without success. Jump error like: Location 'http://svn-path:8181/svn/devSet/issues/${env.chuid}' does not exist Checking out a fresh workspace because C:\Documents and Settings\dnoseda\.hudson\jobs\test\workspace\${env.chuid} doesn't exist Checking out http://svn-path:8181/svn/devSet/issues/${env.chuid} ERROR: Failed to check out http://svn-path:8181/svn/devSet/issues/${env.chuid} org.tmatesoft.svn.core.SVNException: svn: '/svn/!svn/bc/46190/devSet/issues/$%7Benv.chuid%7D' path not found: 404 Not Found (http://svn-path:8181) at org.tmatesoft.svn.core.internal.wc.SVNErrorManager.error(SVNErrorManager.java:64) at org.tmatesoft.svn.core.internal.wc.SVNErrorManager.error(SVNErrorManager.java:51) at I am think that I can not do what I want. Do you know how I can setup the correct configuration to achieve this matter? Thanks for any help. Edit The section of the configurate job that I want to put this parameter is this: <scm class="hudson.scm.SubversionSCM"> <locations> <hudson.scm.SubversionSCM_-ModuleLocation> <remote>http://svn-path:8181/svn/devSet/issues/${env.issueid}</remote> </hudson.scm.SubversionSCM_-ModuleLocation> </locations>

  • Is this feasbile with GIS?

    - by Gnu Engineer
    I'm just getting myself to familiarize with GIS but i like to know before hand if the following is feasible with current GIS apps/tools... I get the point for an address by geocoding. Easy part. Now if the point falls within a boundary (may be a city/county/state) then i need to get the data (any id/flag) associated with the boundary. Based on the id/flag i then apply some business logic. My question is... How do i define the boundary? What tools should i use for it? How can i store the boundary definition in database in order to check if the point falls within it? This has to be done in the back end and not in visual maps as we don't intend to show/use maps. How do i associate my custom data (id/flag) with the above boundary definition? Hope i'm having right assumption on capabilities of GIS. Most of examples what i see is around people trying to show maps with data which is exactly not what i'm looking for. Also please suggest me some tools/books on this.

  • Ruby on Rails - pass variable to nested form

    - by Krule
    I am trying to build a multilingual site using Rails, but I can't figure out how to pass variable to nested form. Right now I am creating nested form like this. @languages.each do @article.article_locale.build(:language_id => language.id) end But i would like to pass value of language to it so i can distinguish fields. Something like this. @languages.each do |language| @language = language @article.article_locale.build(:language_id => language.id) end However, I always end up with language of the last loop iteration. Any way to pass this variable? -- edit -- In the end, since I've got no answer I have solved this problem so it, at least, works as it should. Following code is my partial solution. In model: def self.languages Language.all end def self.language_name language = [] self.languages.each_with_index do |lang, i| language[i] = lang.longname end return language end In Controller: def new @article = Article.new Article.languages.each do |language| @article.article_locale.build(:language_id => language.id) end end In HAML View: -count = 0 -f.fields_for :article_locale do |al| %h3= Article.language_name[count] -count+=1 -field_set_tag do %p =al.label :name, t(:name) =al.text_field :name %p =al.label :description, t(:description) =al.text_area :description =al.hidden_field :language_id It's not the most elegant solution I suppose, but it works. I would really love if I could get rid of counter in view for instance.

  • Which method of 'clearfix' is best?

    - by Pickledegg
    I have the age old problem of a div wrapping a 2 column layout. My sidebar is floated so my container div fails to wrap the content & sidebar. <div id="container"> <div id="content"> </div> <div id="sidebar"> </div> </div> There seem to be numerous methods of fixing the clear bug in FF: <br clear="all"/> overflow:auto overflow:hidden etc. But in my situation, the only one that seems to work correctly is the <br clear="all"/> solution, which is a little bit scruffy. overflow:auto gives me nasty scrollbars, and overflow:hidden must surely have side effects. Also, apparently IE7 is supposed to not suffer from this problem due to its incorrect behaviour, but again, in my situation its suffering the same as FF. Whats the most reliable/best practice method currently available to us?

  • how do I hide certain part of form

    - by yogsma
    I have a form and it contains dropdown box and different div items. Based on selection from dropdown box, I show those div items. But some of the text in those div items are shown when the form is loaded and not when I select the option from dropdown box. The code is somewhat like this <form> <select id=""> <option value="one"> One </option> <option value="two"> Two </option> <option value="three"> Three </option> </select> <div id="onee"> header text ..<table> </table></div> <div id="twoo"> header text ..<table> </table></div> </form> So when I load the page form with select drop down box is shown , but it also shows header text which is within div. How do I hide that text?

  • INSERT INTO ...SELECT syntax error in join operator

    - by user1477356
    I'm trying to write a shopping basket into a order + orderline in a sql database from C# asp.net. the orderline will contain a ordernumber, total price, productid, quantity etc. for every item in the basket. The order itself will contain the ordernumber as primary key and will be linked to the different lines through it. Everything worked fine yesterday, but now as i tried to use a SELECT command in the insert into statement to get things more dynamic i'm getting the above described syntax error. Does anybody know what's wrong with this statement: INSERT INTO [order] (klant_id,totaalprijs,btw,subtotaal,verzendkosten) SELECT klant.id , SUM(orderregel.totaalprijs) , SUM(orderregel.btw) , SUM(orderregel.totaalprijs) - SUM(orderregel.btw) , 7.50 FROM orderregel INNER JOIN klant ON [order].klant_id = klant.id WHERE klant.username = 'jerry' GROUP BY id; the ordernumber in the "order" table is on autonumber, in the asp codebehind there is a for each which handles the lines being written for every product, there's an index set on 0 outside of this loop and is heightened with 1 every end of it. The executenonquery of the order is only executed once at the beginning of the first loop and the lines are added after with MAX(ordernumber) as ordernumber. I hope i have provided enough information and somebody is capable of helping me. Thanks in advance!

  • Indexing table with duplicates MySQL/MSSQL with millions of records

    - by Tesnep
    I need help in indexing in MySQL. I have a table in MySQL with following rows: ID Store_ID Feature_ID Order_ID Viewed_Date Deal_ID IsTrial The ID is auto generated. Store_ID goes from 1 - 8. Feature_ID from 1 - let's say 100. Viewed Date is Date and time on which the data is inserted. IsTrial is either 0 or 1. You can ignore Order_ID and Deal_ID from this discussion. There are millions of data in the table and we have a reporting backend that needs to view the number of views in a certain period or overall where trial is 0 for a particular store id and for a particular feature. The query takes the form of: select count(viewed_date) from theTable where viewed_date between '2009-12-01' and '2010-12-31' and store_id = '2' and feature_id = '12' and Istrial = 0 In MSSQL you can have a filtered index to use for Istrial. Is there anything similar to this in MySQL? Also, Store_ID and Feature_ID have a lot of duplicate data. I created an index using Store_ID and Feature_ID. Although this seems to have decreased the search period, I need better improvement than this. Right now I have more than 4 million rows. To search for a particular query like the one above, it looks at 3.5 million rows in order to give me the count of 500k rows. PS. I forgot to add view_date filter in the query. Now I have done this.

  • Same Origin issue with web service call

    - by Wjdavis5
    My web server runs at http://mypc.com:80 ` Given the following snip: $(window).load(function () { var myURL = "http://mypc.com:8000/PSOCharts/service/HighChart_ColumnChart/i"; $.getJSON(myURL) .done(function(data) {alert(data);}); }); I am running to this error: XMLHttpRequest cannot load http://mypc.com:8000/PSOCharts/service/HighChart_ColumnChart/i. Origin http://mypc.com is not allowed by Access-Control-Allow-Origin. I understand why (I think) b/c my webservice runs at port 8000 which is different from what IIS is running on (port 80). I thought I could get around by using jsonp (according to the jQuery documentation here So I copied the example of making a call to the flickr api, but it isnt working. Any thoughts/sugggestions? UPDATE Ok so my request is being made now: var myURL = "http://192.168.1.104:8000/PSOCharts/service/HighChart_ColumnChart/i?jsoncallback=?"; $.ajax({ url :myURL, dataType: "jsonp", success: function(data) {a(data)} , error: function(){alert("err");}, }); But I am continually hitting the error function, here is what's being returned: [1.4,54.43,49.39,93.23] Now I'm assuming this is b/c the response text doesnt contain any type of callback here is the part of the interface I'm calling: [WebInvoke(Method = "GET", RequestFormat = WebMessageFormat.Json, ResponseFormat = WebMessageFormat.Json, UriTemplate = "HighChart_ColumnChart/{id}?callback={cb}")] List<double> HighChart_ColumnChart(string id,string cb); Here is the actual function being called: public List<double> HighChart_ColumnChart(string id,string cb) { var z = new List<double>(); z.Add(1.4); z.Add(54.43); z.Add(49.39); z.Add(93.23); return z; } when I debug, the CB param is something like : "jQuery19108121746340766549_1372630643878". How do I modify the code to wrap it correctly? Thanks for the help thus far!

  • Check if NSString exists in custom object in NSArray

    - by Paul Peelen
    I have an NSArray with Store objects. Each Store object has two NSString objects; StoreID and Name. I would like to check quickly if an ID exists in this NSArray with Store objects. Example: Store *s1 = [[Store alloc] init]; s1.name = @"Some Name"; s1.id = @"123ABC"; Store *s2 = [[Store alloc] init]; s2.name = @"Some Other Name"; s2.id = @"ABC123"; NSArray *array = [[NSArray alloc] initWithObjects:s1, s2, nil]; NSString *myIdOne = @"ABCDEF"; NSString *myIdTwo = @"123ABC"; BOOL myIdOneExists = ...? BOOL myIdTwoExists = ...? Its the ...? I need to figure out. I know I can do this using a for loop and break when found... but this seems to me like an nasty approach since the NSArray could contain thousands of objects,... theoretically. So I would like to know about a better solution.

  • Reading HTML header info of files via JS

    - by Morten Repsdorph Husfeldt
    I have a product list that is generated in ASP. I have product descriptions for each product in an HTML file. Each HTML file is named: <product.id>.html. Each HTML file size is only 1-3 kb. Within the HTML file is <title> and <meta name="description" content="..." />. I want to access these in an efficient way so that I can output this as e.g.: document.write(<product.id>.html.title);<br/> document.write(<product.id>.html.description); I have a working solution for the individual products, where I use the description file - but I hope to find a more efficient / simple approach. Preferably, I want to avoid having 30+ hidden iframes - Google might think that I am trying to tamper with search result and blacklist my page. Current code: <script type="text/javascript"> document.getElementById('produkt').onload = function(){ var d = window.frames[frame].document; document.getElementById('pfoto').title = d.title : ' '; document.getElementById('pfoto').alt = d.getElementsByName('description')[0].getAttribute('content', 0) : ' '; var keywords = d.getElementsByName('keywords')[0].getAttribute('content', 0) : ' '; }; </script>

  • [Rails] checkbox to update attribute

    [Updated a bit] I have a Task model that has a :completed boolean attribute. If I click on it I want it to execute the 'finish' method. The main problem is that I am displays a series of checkboxes in a list and subsequent checkboxes after the first one are ignored. The method is never called for the given task/checkbox combo. I have this chunk of code in my view: <% current_user.tasks.each do |t|%> <% if t.completed == false %> <%= check_box_tag :completed, true, checked = false %> <%= observe_field :completed, :url => { :controller => 'tasks', :action => :finish , :id => t.id }, :frequency => 0.25, :update => :completed, :with => true %> and my finish method looks like this: def finish @task = Task.find(params[:id]) new = {:completed => true} @task.update_attributes(new) render :update do |page| page.replace_html "taskListing", :partial => 'home/task_listing' end

    Assume I have these tables, from which i need to display search results in a browser: Table: Containers id | name 1 Big Box 2 Grocery Bag 3 Envelope 4 Zip Lock Table: Sale id | date | containerid 1 20100101 1 2 20100102 2 3 20091201 3 4 20091115 4 Table: Items id | name | saleid 1 Barbie Doll 1 2 Coin 3 3 Pop-Top 4 4 Barbie Doll 2 5 Coin 4 I need output that looks like this: itemid itemname saleids saledates containerids containertypes 1 Barbie Doll 1,2 20100101,20100102 1,2 Big Box, Grocery Bag 2 Coin 3,4 20091201,20091115 3,4 Envelope, Zip Lock 3 Pop-Top 4 20091115 4 Zip Lock The important part is that each item type only gets one record/row in the return on the screen. I accomplished this in the past by returning multiple rows of the same item and using a scripting language to limit the output. However, this makes the ui overly complicated and loopy. So, I'm hoping I can get the database to spit out only as many records as there are rows to display. This example may be a bit extreme because of the 2 joins needed to get to the container from the item (through the sale table). I'd be happy for just an example query that outputs this: itemid itemname saleids saledates 1 Barbie Doll 1,2 20100101,20100102 2 Coin 3,4 20091201,20091115 3 Pop-Top 4 20091115 I can only return a single result in a subquery, so I'm not sure how to do this.

  • jQuery hide all table rows which contain a hidden field matching a value

    - by Famous Nerd
    Though I don't doubt this has been answered I cannot find a great match for my question. I have a table for which I'd like to filter rows based on whether or not they contain a hidden field matching a value. I understand that the technique tends to be "show all rows", "filter the set", "show/hide that filtered set" I have the following jquery but I'm aweful with filter and my filtered set seems to always contain no elements. my table is the usual <table> <tr><td>header></td><td>&nbsp;</tr> <tr> <td>a visible cell</td><td><input type='hidden' id='big-asp.net-id' value='what-im-filtering-on' /> </td> </tr> </table> My goal is to be able to match on tr who's descendent contains a hidden input containing either true or false. this is how I've tried the selector (variations of this) and I'm not even testing for the value yet. function OnFilterChanged(e){ //debugger; var checkedVal = $("#filters input[type='radio']:checked").val(); var allRows = $("#match-grid-container .tabular-data tr"); if(checkedVal=="all"){ allRows.show(); } else if(checkedVal=="matched"){ allRows.show(); allRows.filter(function(){$(this).find("input[type='hidden'][id~='IsAutoMatchHiddenField']")}).hide(); } else if(checkedVal=="unmatched"){ } } Am I way off with the filter? is the $(this) required in the filter so that i can do the descendant searching? Thanks kindly

  • Mixing has_one and has_and_belongs_to_many associations

    - by Thomas
    I'm trying to build a database of urls(links). I have a Category model that has and belongs to many Links. Here's the migration I ran: class CreateLinksCategories < ActiveRecord::Migration def self.up create_table :links_categories, :id => false do |t| t.references :link t.references :category end end def self.down drop_table :links_categories end end Here's the Link model: class Link < ActiveRecord::Base validates :path, :presence => true, :format => { :with => /^(#{URI::regexp(%w(http https))})$|^$/ } validates :name, :presence => true has_one :category end Here's the category model: class Category < ActiveRecord::Base has_and_belongs_to_many :links end And here's the error the console kicked back when I tried to associate the first link with the first category: >>link = Link.first => #<Link id: 1, path: "http://www.yahoo.com", created_at: "2011-01-10... >>category = Category.first => #<category id : 1, name: "News Site", created_at: "2011-01-11... >>link.category << category => ActiveRecord::StatementInvalid: SQLite3::Exception: no such column : categories.link_id: Are my associations wrong or am I missing something in the database? I expected it to find the links_categories table. Any help is appreciated.
