问题 I need to do two different JSON requests and combine those requests in one function. I would have liked to use the following construction: $.when( $.getJSON(url1), $.getJSON(url2) ).done(function(data1, data2) { someFunction(data1, data2); }); Unfortunately, for this project we are using jQuery 1.4 and $.when was introduced since jQuery 1.5. Is there some equivalent for this in jQuery 1.4? Thanks in advance! 回答1: To implement this functionality, I have done an array where each element is a

问题 I've seen a lot of questions about this already, but I'm stumped! Please help! I have a customvalidator. It's firing but it's not preventing postback. Please help me in doing so! I can see that console.log registers before the post. But, it posts back anyway. How do I prevent the postback? I've tried adding a control to validate, and validate empty text equal to true. I also tried adding e.preventdefault, which did not work :( How can I prevent the postback? <script type="text/javascript"> //

问题 I'm using the following jquery code to show a contextual delete button only for table rows we are hovering with our mouse. This works but not for rows that have been added with js/ajax on the fly... Is there a way to make this work with live events? $("table tr").hover( function () {}, function () {} ); 回答1: jQuery 1.4.1 now supports "hover" for live() events, but only with one event handler function: $("table tr").live("hover", function () { }); Alternatively, you can provide two functions,

问题 I recently decided to try jQuery 1.4, excited that I would finally have support for live event handlers that work for change events in IE. However, it seems like they don't always work. If I try to assign a live change handler on a select element, it doesn't work when I change it in IE. I tried this in IE 6, 7, and 8. In every other browser I tried (Firefox, Chrome, Safari), it works fine. I tried putting the command to assign the handler within the ready function, and that didn't fix it.

问题 I'm trying to insert data after an existing DOM element. I'm getting an error "Invalid argument." -- this.parentNode.insertBefore This is not working in IE8 or IE7. Ideas? Jfiddle example: http://jsfiddle.net/zJ3Fe/ <a href="#" id="delete_promo">Click</a> <div id="customer-info" class="span-12"> <form id="UserFormCheckoutForm" method="post" action="/chicagophotographycenter/checkout" accept-charset="utf-8"><div style="display:none;"><input type="hidden" name="_method" value="POST" /></div>

问题 This is my JavaScript, using jQuery: $("#E_DIV_H input[value='E,F']").attr('checked', 'checked'); var data = $('#E_DIV_H').html(); $('#copy').html(data); When it copies the data from one <div> ( #E_DIV_H ) to another DIV ( #copy ), it unchecks the check box, which should already be checked due to the following code! $("#E_DIV_H input[value='E,F']").attr('checked', 'checked'); Using Firebug, I see that .attr('checked', 'checked') is checking the check box without adding the attribute. Is there

问题 My problem is that I am not sure how to use .delegate for the following scenario: our application has a voting system to which several rounds or steps can be added. every time a new step is added there is a list of options that defines how the round/step is to be won. <select class="listOfOptions"> <option value="U">Unanimous</option> <option value="M">Majority</option> <option value="C" class="customOption"># of votes…</option> </select> now when an option is selected the following code runs

问题 I am using jqModal plugin which relies on jqDnR for drag and resize support. After I upgraded jQuery to 1.4, modal boxes stopped responding to "drag" event. Does anyone know why this is happening? Thanks.. 回答1: Using the version downloaded directly from the author's website (here), on lines 19, character 38 and 27, character 23. Replace $() with $(document) That's how I got jqDnR to work with 1.4 回答2: see the jQuery 1.4 release announcement - Backwards-Incompatible Changes. We’ve also written
