Adding a class

It is one of the common tasks that a developer performs on a web page - adding and removing classes. For adding a class, we have to use addClass() function.

Listing 9

$("a").addClass("tableStyle");

It has been assumed that tableStyle is a predefined class. Similarly for removing a class, we can use removeClass () function.

Chainability

jQuery allows us to concatenate together operations into a single expression. Every method within jQuery returns the query object itself, allowing the programmer to "chain" upon it. In other words, most of the jQuery wrapper methods returns a reference to the jQuery object itself so that we can go on adding operations to a single expression when we need to perform multiple manipulations on the wrapped object. Let us take the example of the statements below.

Listing 10

$('#someId').addclass('someClass');
$('#someId').show();

The operation performed by the above two statements can be performed in one statement as shown below.

Listing 11

$('#someId').addclass('someClass').show();

Like the above examples, there are a lot of functionalities which can be performed using jQuery using the minimal code.
