:has() Selector

has selector

version added: 1.1.4jQuery(':has(selector)')

  • selector
    Any selector.

Description: Selects elements which contain at least one element that matches the specified selector.

The expression $('div:has(p)') matches a <div> if a <p> exists anywhere among its descendants, not just as a direct child.

Additional Notes:

  • Because :has() is a jQuery extension and not part of the CSS specification, queries using :has() cannot take advantage of the performance boost provided by the native DOM querySelectorAll() method. For better performance in modern browsers, use $("your-pure-css-selector").has(selector/DOMElement) instead.

Example:

Adds the class "test" to all divs that have a paragraph inside of them.

<!DOCTYPE html>
<html>
<head>
  <style>
  .test{ border: 3px inset red; }
  </style>
  <script src="http://code.jquery.com/jquery-1.7rc2.js"></script>
</head>
<body>
  <div><p>Hello in a paragraph</p></div>

  <div>Hello again! (with no paragraph)</div>
<script>$("div:has(p)").addClass("test");</script>

</body>
</html>
