jQuery toggleCLass()方法用于从所选元素中添加或删除一个或多个类。此方法在添加和删除一个或多个类名之间切换。它检查每个元素是否有指定的类名。如果已经设置了类名，则将其删除；如果缺少类名，则将其添加。

这样，它会产生切换效果。它还可以帮助您通过使用switch参数指定仅添加或仅删除。

句法：

$(selector).toggleClass(classname,function(index,currentclass),switch)

Parameter	Description
classname	It is a mandatory parameter. It specifies one or more class name to add or remove. If you use several classes then separate them by space.
function (index, currentclass)	It is an optional parameter. It specifies one or more class names that you want to add or remove. Index: It provides the index position of the element in the set. Currentclass: It provides the current class name of the selected element.
switch	It is also an optional parameter. It is a Boolean value which specifies whether the class should be added (true) or removed (false).

让我们以一个示例来演示jQuery toggleClass()方法的效果。
