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

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').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.

    HTML:
    <p><span>Look:</span> <span>This is some text in a paragraph.</span> <span>This is a note about it.</span></p>
    CSS:
    .highlight{background-color: yellow}
    Code:
    $("p span").first().addClass('highlight');
