In jQuery, you can get elements with CSS class name and id easily.

For example,

1. ID: #id

  • $(‘#idA’) – selects all elements that have an id of ‘idA’, regardless of its tag name.
  • $(‘div#idA’) – selects all div elements that has an id of ‘idA’.

2. Class: .classname

  • $(‘.classA’) – selects all elements that have an class name of ‘classA’, regardless of its tag name.
  • $(‘div.classA’) – selects all div elements that has an class name of ‘classA’.

Full Example

<head>
<title>jQuery Get element with class name and id</title>
 
<script type="text/javascript" src="jquery-1.3.2.min.js"></script>
 
</head>
