.first()Returns: jQuery

Description: Reduce the set of matched elements to the first in the set.

  • version added: 1.4.first()

    • This method does not accept any arguments.

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

Consider a page with a simple list on it:

  <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>

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

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

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


Highlight the first span in a paragraph.

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