  • jQuery: Listen to changes within a DIV and act accordingly

    - by Chris
    I have a function that grabs an XML document and transforms it according to an XSL document. It then places the result into a div with the id laneconfigdisplay. What I want to do is, separate to the transformation logic, setup a jQuery change event for that div so I can tell when it has changed, and run some jQuery code. I have tried the following, but it does not work! $(document).ready(function() { $('#laneconfigdisplay').change(function() { alert('woo'); }); //Do XML / XSL transformation here }); <!-- HTML code here --> <div id="laneconfigdisplay"></div> What am I doing wrong?

  • jquery "this" binding issue on event handler

    - by clyfe
    In jquery an event hadler's binding is the event generating DOM element (this points to the dom element). In prototype to change the binding of an event handler one can use the bindAsEventListener function; How can I access both the instance and the DOM element from a event handler? Similar to http://stackoverflow.com/questions/117361/how-can-i-bind-an-event-handler-to-an-instance-in-jquery function Car(){ this.km = 0; $("#sprint").click(this.drive); //setup event handler } // event handler // in it I need to access both the clicked element // and the binding object (instance of car) Car.prototype.drive = function(){ this.km += 10; // i'd like to access the binding (but jq changes it) this.css({ left: this.km }); // also the element // NOTE that is inside this function I want to access them not elsewhere } var car = new Car();

  • Toggle alternative

    - by Nutmeg
    In a contactform I am using both the jQuery validation plug-in 1.3 and the following (slide) script: $(document).ready(function() { // Expand Panel $("#open").click(function(){ $("div#contact").slideDown("slow"); }); // Collapse Panel $("#close").click(function(){ $("div#contact").slideUp("bounce"); }); // Switch buttons from "Log In | Register" to "Close Panel" on click $("#toggle a").click(function () { $("#toggle a").toggle(); }); }); Problem is that the validation plug-in 1.3 uses the following segment: addWrapper:function(toToggle){if(this.settings.wrapper)toToggle.push(toToggle.parents(this.settings.wrapper));return toToggle;}, which conflicts with the slide code. What's the smartest way to go about this? Using the toggleClass instead? Thanks for your help!

  • Image Replacement (JS/JQuery) working in IE but not FF

    - by Sunburnt Ginger
    I have tried multiple solutions for replacing broken images (both JS & jQuery) and all work perfectly with IE but not in FF, is there a reason for this? Are images handled differently in FF that may cause this? JQuery Example: $("img").error(function(){ $(this).unbind("error").attr("src", "nopic.jpg"); }); Javascript Example: (triggered by onError event in img tag) function noimage(img){ img.onerror=""; img.src="nopic.jpg"; return true; } Both of these examples work perfectly in IE but not at all in FF. What gives? Thanks in advance!

  • Triggering jquery event function at page load

    - by lazysoundsystem
    Here's a little jQuery function that does what I want when a checkbox is clicked, but I have a basic gap in my knowledge: How to register this so that it deals with checkboxes that are already clicked when the page loads? $(document).ready(function() { $('fieldset input:checkbox').click(function() { if ($(this).attr('name') == 'foo') { // hide checkbox 'bar' } else { // show checkbox 'bar' } } }); If I use .trigger('click'), it clicks (or unclicks) all the boxes on page load. I can think of a few ways to do this that would involve repeating portions of the code, but I just know that jQuery already has an elegant answer for this...

  • Highlight multiple rows using jQuery

    - by cf_PhillipSenn
    I'm putting together a succinct jQuery matrix because I'm having a hard time navigating around on the jQuery site, and the cheat sheets don't seem to provide me what I want either. Here's how I highlight the rows: $('.eq').hover(function() { $('.eq').toggleClass('highlight'); }); $('.is').hover(function() { $('.is').toggleClass('highlight'); }); Q: How can I write a function that says "toggle everything in the same class as what is being hovered over"? Something like: function toggle(that){ $(that.className).toggleClass('highlight'); }

  • How to register a VB.Net User Control with jQuery

    - by BornReady
    Greetings and thank you in advance for the help. I created a user control in VB.NET that uses a jQuery datepicker. I am at an impasse. The code I have works for one datepicker control on the page but because I can only register the client script once, it will not work for multiple instances/datepickers on the same page. What is the best way to go about initiating the jQuery script for this control so I can use it multiple times on one page? Can I append to ClientScript.RegisterStartupScript? Thanks again.

  • Rails 3: jQuery form not working.

    - by donald
    Hi, I have jquery working on my Rails app using the gem 'jquery-rails'. I also have a search form working correctly. However, when I add :remote => true the form stops working. <%= form_tag services_path, :method => :get, :remote => true do %> <%= text_field_tag :search, params[:search] %> <%= submit_tag "Search", :name => nil %> </div> <% end %> I have also added a index.js.erb but it has no effect on it. For some reason the :remote = true makes the form to stop working. Any reason why? Thanks

  • jQuery display problem?

    - by SLAPme
    How do I hide the #changes-saved code using jQuery? For example let's say the code is displayed when the user clicks the submit button and then leaves the current web page and then returns back to the web page and the #changes-saved is no longer displayed until the submit button is clicked again. Here is the jQuery code. $(function() { $('#changes-saved').hide(); $(".save-button").click(function() { $.post($("#contact-form").attr("action"), $("#contact-form").serialize(), function(html) { $("div.contact-info-form").html(html); $('#changes-saved').append('<li>Changes saved!</li>').show().pause(1000).hide(); }); return false; // Prevent normal submit. }); });

  • jQuery Photo Search Results Pagination using AJAX and JSON

    - by Mark Richman
    I have a "photo search" page that needs to present search results in a 5x5 grid of photo thumbnails. I'd like to populate this grid using the JSON results of a jQuery $.ajax() call to my ASP.NET web service. Where I'm struggling is with pagination, where clicking [First][Prev][1][2][3]...[20][21][Next][Last] will call back again via ajax and repopulate the results with the appropriate images. So I need to find a solution to both the pagination control itself and the search results. Is there a jQuery plugin for this, or something I can easily adapt for my purposes?

  • How to do REST with PUT and DELETE

    - by Svish
    It says about the type option of the jQuery.ajax() method that The type of request to make ("POST" or "GET"), default is "GET". Note: Other HTTP request methods, such as PUT and DELETE, can also be used here, but they are not supported by all browsers. So... Does that mean that PUT and DELETE won't work if the browser does not support it, or just that PUT and DELETE can not be done natively by the user in the browser? If I can't or shouldn't use those, what do people usually do instead? Send the method as a a GET or POST parameter instead? Or?

    - by PandaWood
    I am writing a jquery plugin in coffeescript but am not sure how to get the function wrapper part right. My coffeescript starts with this line: $.fn.extend({ Which creates the javascript with a function wrapper: (function() { $.fn.extend({ but I want a '$' passed in like this: (function($) { $.fn.extend({ Similar for the ending I have... nothing in particular in coffeescript. I get this in javascript: })(); But would like this: })(jQuery); Does anyone know how to achieve this with the coffeescript compiler? Or what is the best way to get this done within coffeescript?

  • jquery - clone nth row of a table?

    - by John
    I'm trying to use jquery to clone a table row everytime someone presses the add-row button. Can anyone tell me what's wrong with my code? I'm using HTML + smarty templating language in my view. Here's what my template file looks like: <table> <tr> <td>Description</td> <td>Unit</td> <td>Qty</td> <td>Total</td> <td></td> </tr> <tbody id="entries"> {foreach from=$arrItem item=i name=inv} <tr> <td> <input type="hidden" name="invoice_item_id[]" value="{$i.invoice_item_id}"/> <input type="hidden" name="assignment_id[]" value="{$i.assignment_id}" /> <input type="text" name="description[]" value="{$i.description}"/> </td> <td><input type="text" class="unit_cost" name="unit_cost[]" value="{$i.unit_cost}"/></td> <td><input type="text" class="qty" name="qty[]" value="{$i.qty}"/></td> <td><input type="text" class="cost" name="cost[]" value="{$i.cost}"/></td> <td><a href="javascript:void(0);" class="delete-invoice-item">delete</a></td> </tr> {/foreach} </tbody> <tfoot> <tr><td colspan="5"><input type="button" id="add-row" value="add row" /></td></tr> </tfoot> </table> Here's my Jquery Javascript call, which I know gets fired when I put in an alert() statement. So the problem is with me not knowing how jquery works. $('#add-row').live('click', function() {$('#entries tr:nth-child(0)').clone().appendTo('#entries');}); So what am I doing wrong?

  • I want jQuery validator to add a class to the form element's parent

    - by Eystein
    How do I use jQuery validator to add/remove a classname (e.g. validate) on the form element's parent <li> so I can style everything related to that element by only setting the one classname? The markup is <li class="validate"> <label for="product">Product of interest <abbr title="Required field">*</abbr></label> <input id="product" type="text" name="product" value="" placeholder="e.g. school bench" class="required" minlength="2"> <!-- Hidden by CSS unless parent has 'validate' class --> <label for="product" class="description">Please name a product.</label> </li> and the default jQuery is $("#commentForm").validate();

  • jQuery click listener on <object> in IE failing

    - by Steve Meisner
    $("#listView object.modal").click(function(){ // Get the ID of the clicked link: var link = $(this).closest("h2").attr("title"); var id = $(this).closest("div").attr("id"); showDialog(link, id); return false; }); This fires a modal (jQuery UI). It it working in FF, Chrome/Safari but not in IE 7/8. Is there something I'm missing here? Big Picture: We're using a swf to render custom type and there is a link in the rendered (flash) content. We're hoping to catch the link action in the jQuery listener so we don't have to extend our swf have an optional param to return false on link click. We thought we got around it, until IE testing commenced... Let me know if any more info is needed. Thanks!

  • Jquery How to use history plugin?

    - by Martijn
    In my web application I am using ajax and now I'd like the back and forward browser buttons to work. So I went looking for a jquery history plugin and found this one: http://stilbuero.de/jquery/history In my code I use a function to load a page: function loadDocument(id, doc) { $("#DocumentContent").show(); // Clear dynamic menu items $("#DynamicMenuContent").html(""); $("#PageContent").html(""); // Load document in frame $("#iframeDocument").attr("src", 'ViewDoc.aspx?id=' + id + '&doc=' + doc + ''); // Load menu items $("#DynamicMenuContent").load("ShowButtons.aspx"); } As you can see I want my pages to load within an Iframe. Can someone tell me how I can use a history plugin so that the brwoser buttons will work? I don't really care which plugin it is, as long as the browser buttons work. I prefer an easy to use plugin.

  • jQuery getScript function with frames

    - by user210099
    Hello.. I'm a novice at Javascript/Jquery programming, so an apology if this is a simple/silly question. I am trying to use the jQuery .getScript() function to refresh part of an existing webpage. This webpage must be run on a local file system, and a large amount of the formatting is done using frames. Right now, there’s three main frames- a sidebar which displays possible “scopes” to choose from, a main frame which displays the majority of the contents of the webpage, and a footer frame. The main entry into the page is in an index.html file, which loads a sidebar.html, main.html, and footer.html file into each of the respective frames. In turn, the main.html has a number of javascript files which it loads, the main being a main.js, which contains numerous functions to format/process the contents for this main window. After loading this javascript file, main.html loads a few javascript files, which contain the data which is going to be displayed in the main frame. These files that are loaded have a fixed data structure, and are dependent on the functions that were loaded by the main.js file. Loading the webpage works fine now, but when a user tries to switch to another “scope”, the whole webpage is reloaded to make the switch. The only difference in the webpage is the content in the main.js frame, loaded in by a different set of .js files. Enough text, let’s look at some code. When the webpage loads, I tried to add a simple call to the getScript function in a .js file at the index.html level which handles switching scopes. This file, newFile, has different data definitions than the previously loaded oldFile.js which was loaded in the main.html file. $.getScript(/js/newFile.js); However this doesn’t work, since newFile.js depends on a parseData() function which is in main.js. If I open firebug up, parseData is not located in the dom tab, which I assume is related to some scoping issue with the main.html and main.js file existing in a different frame. I tried to do some targeting to the correct “frame” but I don’t think I understand jQuery enough to know what is happening. $(window.parent.frames[0]).getScript(/js/newFile.js); Any suggestions? If I were to type into firebug console “parseData” it can not find it: “ReferenceError: parseData is not defined” However, if I type in window.parent.frames[1].parseData, it can find the function. Sorry about all the rambling and poor understanding of javascript. Hopefully someone can provide some assistance! Thanks

  • add navigation buttons with highlight to jQuery Cycle

    - by JJ Nold
    I am currently using jQuery cycle to display featured projects. I currently have the next and prev buttons setup, I also have four rounded buttons in between. I would like them to function as both a link to the corresponding slide as well as add a class to the button who's slide is currently active. I have the nav setup and the active class setup I just need the jQuery. You can see the code at http://jjnold.com/dev in the main slider at the top. I was thinking it's probably something like this to assign the class but I'm not sure how to link to the corresponding slide and have them work together. Any help is greatly appreciated. $('.featuredNavInt a').click(function() { $('.featuredNavInt a').removeClass('active'); $(this).addClass('active'); });
