This method takes one or more class names as its parameter. In the first version, if an element in the matched set of elements already has the class, then it is removed; if an element does not have the class, then it is added. For example, we can apply .toggleClass() to a simple <div>:
+
+
+ .toggleClass()
+
+ 1.0
+
+ One or more class names (separated by spaces) to be toggled for each element in the matched set.

+ A function that returns class names to be toggled in the class attribute of each element in the matched set. Receives the index position of the element in the set, the old class value, and the state as arguments.

+ Add or remove one or more classes from each element in the set of matched elements, depending on either the class's presence or the value of the state argument.

- Applying .toggleClass( "bounce spin" ) to the same <div> alternates between <div class="tumble bounce spin"> and <div class="tumble">.
- The second version of .toggleClass() uses the second parameter for determining whether the class should be added or removed. If this parameter's value is true, then the class is added; if false, the class is removed. In essence, the statement:

- As of jQuery 1.4, if no arguments are passed to .toggleClass(), all class names on the element the first time .toggleClass() is called will be toggled. Also as of jQuery 1.4, the class name to be toggled can be determined by passing in a function.
