jQuery removeClass()不删除所有类 [英] jquery removeClass() not removing all classes

问题描述

我有一个像这样的元素:

I have an element like this:

<div class="one two three" id="waterhorse">horse</div>

当我在浏览器控制台中运行以下代码时:

When I run this code in the browser console:

$("#waterhorse").removeClass();

我明白了:

[<div id=​"waterhorse" class=​"one two three">​horse​</div>​]

换句话说，它行不通；它不会删除元素上的任何类.不幸的是，我无法在jsfiddle中复制它.

In other words, it doesn't work; it doesn't remove any classes on the element. I unfortunately can't reproduce it in jsfiddle.

但是，我可以删除特定的类:

However, I can remove a specific class:

$("#waterhorse").removeClass("two");

此外，这将删除所有类:

Also, this will remove all classes:

$("#waterhorse").removeAttr("class");

有人知道后者为什么可以删除所有类，而前者却不能吗?

Any idea why the latter works to remove all classes, but the former doesn't?

推荐答案

似乎这是jQuery和jQueryUI不能很好地配合使用的已知问题:

Seems like this is a known problem with jQuery and jQueryUI not playing nicely together:

jQuery的奇怪问题.removeClass()没有做任何事情

以上答案是使用.removeAttr('class')而不是.removeClass()

The answer above is a workaround that uses .removeAttr('class') instead of .removeClass()
