jQuery Simple Spy no longer works with jQuery 1.5

阅读更多关于 jQuery Simple Spy no longer works with jQuery 1.5

I'm trying to use Remy Sharp's Simple Spy (http://jqueryfordesigners.com/simple-jquery-spy-effect) with jQuery 1.5. It works fine with 1.4, but in 1.5 it does not load any additional comments after the first one disappears. Can anyone see what needs to be updated in the code so it will work with 1.5? $(function () { $('ul.spy').simpleSpy(); }); (function ($) { $.fn.simpleSpy = function (limit, interval) { limit = limit || 4; interval = interval || 4000; return this.each(function () { // 1. setup // capture a cache of all the list items // chomp the list down to limit li elements var $list = $

问题 In jquery 1.5, what is the recommend approach for mocking ajax requests? Is it to use the ajax extension transports? http://api.jquery.com/extending-ajax/#Transports 回答1: Have you tried extending $.ajax with the 1.5 update and finding out if you can call .resolve on the jqXHR . As long as you get it to not remove the .promise read-only Deferred object you should be able to fake a completion of the ajax request. Alternative you can always just mock out a node.js server. Anywhere you can hook

jQuery 1.5 AJAX call fails with “invalid label” for JSON requests

阅读更多关于 jQuery 1.5 AJAX call fails with “invalid label” for JSON requests

I've just upgraded from version 1.4 to version 1.5 of jQuery, and now my AJAX calls always fail with the "invalid label" error. An example request is: jQuery.ajax({ async: false , dataType: "json" , error: function (xhr, status, error) { ... } , success: function (data, status, xhr) { ... } , type: "post" , url: "ajax/request.asp" }); On the net I found this error is raised when the returned JSON is not wrapped with jQuery's callback (e.g. jQuery1234({ "something": "abcd" }) . The problem is I'm returning a JSON, not a JSONP (and I state it in the AJAX request), so why I must specify a

Why is jqXHR.responseText returning a string instead of a JSON object?

阅读更多关于 Why is jqXHR.responseText returning a string instead of a JSON object?

I have an $.ajax() request with the dataType set to "json." The server is returning JSON with the correct mime type of "application/json." And yet the responseText in my jqXHR object is always a string. What am I doing wrong? Is this how it's supposed to work? Here's how I'm making the call: var options = { dataType:'json', type: 'GET', url: "http://example.com/api/" }; var key = "PassToCallback"; var jqXHRObject = $.ajax(options).then( function(data, textStatus, jqXHR, key) { this.success(data, textStatus, jqXHR, key); }, function(jqXHR, textStatus, errorThrown) { this.error(jqXHR, textStatus

How to use jQuery Deferred with custom events?

阅读更多关于 How to use jQuery Deferred with custom events?

I have two abstracted processes (e.g. managed within js objects using the revealing module pattern that do not expose their internals) that fire custom events when they complete. I want to perform an action when both custom events have fired. The new Deferred logic in jQuery 1.5 seems like it would be an ideal way to manage this, except that the when() method takes Deferred objects that return a promise() (or normal js objects, but then when() completes immediately instead of waiting, which is useless to me). Ideally I would like to do something like: //execute when both customevent1 and

问题 My code works fine in jquery 1.4 and i try upgrade it to 1.5.
