jQuery toggleClass() Method

The jQuery toggleClass() Method toggles between adding and removing one or more class names from each element in the set of matched elements.

Example of jQuery toggleClass:

Suppose, we have below HTML:

<div class="myclass">Your text here.</div>

When you apply $( “.myclass” ).toggleClass( “newClass” ), we get the following:

<div class="myclass newClass">Your text here.</div>

Again, if you apply $( “.myclass” ).toggleClass( “newClass” ) then you can get the value as it was before:

<div class="myclass">Your text here.</div>
