.last()

Reduce the set of matched elements to the final one in the set.

Given a jQuery object that represents a set of DOM elements, the .last() method constructs a new jQuery object from the last element in that set.

Consider a page with a simple list on it:

<ul>
  <li>list item 1</li>
  <li>list item 2</li>
  <li>list item 3</li>
  <li>list item 4</li>
  <li>list item 5</li>
</ul>

We can apply this method to the set of list items:

$( "li" ).last().css( "background-color", "red" );

The result of this call is a red background for the final item.

.last()

version added: 1.4

This method does not accept any arguments.

Examples:

Highlight the last span in a paragraph.

<!doctype html>
<html lang="en">
<head>
  <meta charset="utf-8">
  <title>last demo</title>
  <style>
  .highlight {
    background-color: yellow;
  }
  </style>
  <script src="https://code.jquery.com/jquery-1.10.2.js"></script>
</head>
<body>
 
<p><span>Look:</span> <span>This is some text in a paragraph.</span> <span>This is a note about it.</span></p>
 
<script>
$( "p span" ).last().addClass( "highlight" );
</script>
 
</body>
</html>
