Odd issue with jQuery .removeClass() not doing anything
提问by jbabey
I have some code that adds classes to an element and then tries to remove them and add different ones 1 second later. I'm getting some very odd behavior that I can't even reproduce in a simple jsfiddle example.
我有一些代码将类添加到元素，然后尝试删除它们并在 1 秒后添加不同的类。我得到了一些非常奇怪的行为，我什至无法在一个简单的jsfiddle 示例中重现。
Here's the relevant JavaScript code I have:
这是我拥有的相关 JavaScript 代码：
console.log('before destroyed: ' + currentTile.get(0).className);
currentTile.addClass(classes.destroyed);
console.log('after destroyed: ' + currentTile.get(0).className);
setTimeout(function () {
console.log('before blanking: ' + currentTile.get(0).className);
currentTile.removeClass().addClass(classes.blank + ' ui-draggable');
console.log('after blanking: ' + currentTile.get(0).className);
}, 2000);
And here is what the console is saying:
这是控制台所说的：
As you can see, adding the destroyedclass works fine, but the call to removeClass()inside of the setTimeoutappears to be doing nothing, and then the .addClass(classes.blank + ' ui-draggable');also appears to be working fine. Also, if I pass a single class to removeClassit removes that one class without a problem.
如您所见，添加destroyed类工作正常，但对removeClass()内部的调用setTimeout似乎没有任何作用，然后.addClass(classes.blank + ' ui-draggable');似乎也工作正常。此外，如果我将单个类传递给removeClass它，则可以毫无问题地删除该类。
If it were an issue of context or currentTilebeing the wrong element, I would think the addClasswould also fail? Anyone have any idea what is going on here?
如果是上下文问题或者currentTile是错误的元素，我认为addClass这也会失败？任何人都知道这里发生了什么？
Additional info: jQuery latest (v.1.9.0 I think), jQuery UI v 1.10.0, Chrome v.24.0.1312.56 m
附加信息：jQuery 最新版（我认为是 v.1.9.0）、jQuery UI v 1.10.0、Chrome v.24.0.1312.56 m
Edit: The problem appears to be directly related to jQuery UI, and can be seen happening in this fiddle.
编辑：问题似乎与 jQuery UI 直接相关，并且可以在这个 fiddle 中看到。
Edit 2: This was confirmed as a bug in jQuery, and has been fixed.

Try using .removeAttr('class')rather than .removeClass().
尝试使用.removeAttr('class')而不是.removeClass().
