本章将讨论removeClass（）方法，该方法是用于管理jQueryUI视觉效果的方法之一。 removeClass（）方法从元素中删除应用的类。

removeClass（）方法在对所有样式更改进行动画处理时，将指定的类删除到匹配的元素。

removeClass（）方法的基本语法如下：

.removeClass( className [, duration ] [, easing ] [, complete ] )

Sr.No.	Parameter & Description
1	className This is a String containing one or more CSS classes (separated by spaces) to be removed.
2	duration This is of type Number or String, and indicates the number of milliseconds of the effect. A value of 0 takes the element directly in the new style, without progress. Its default value is 400.
3	easing This is of type String and indicates the way to progress in the effect. Its default value is swing. Possible values are here.
4	complete This is a callback method called for each element when the effect is complete for this element.

在1.9版中，此方法现在支持子选项，该选项还将为后代元素设置动画。
