has selector
Description: Selects elements which contain at least one element that matches the specified selector.
-
version added: 1.1.4jQuery( ":has(selector)" )
selector: Any selector.
The expression $( "div:has(p)" ) matches a <div> if a <p> exists anywhere among its descendants, not just as a direct child.
Additional Notes:
- Because
:has()is a jQuery extension and not part of the CSS specification, queries using:has()cannot take advantage of the performance boost provided by the native DOMquerySelectorAll()method. For better performance in modern browsers, use$( "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 lang="en">
<head>
<meta charset="utf-8">
<title>has demo</title>
<style>
.test {
border: 3px inset red;
}
</style>
<script src="https://code.jquery.com/jquery-3.5.0.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>
