:last selector

Selects the last matched element.

Note that :last selects a single element by filtering the current jQuery collection and matching the last element within it.

Because :last is a jQuery extension and not part of the CSS specification, queries using :last cannot take advantage of the performance boost provided by the native DOM querySelectorAll() method. To achieve the best performance when using :last to select elements, first select the elements using a pure CSS selector, then use .filter(":last").

jQuery( ":last" )

version added: 1.0

Examples:

Finds the last table row.

<!doctype html>
<html lang="en">
<head>
  <meta charset="utf-8">
  <title>last demo</title>
  <script src="https://code.jquery.com/jquery-1.10.2.js"></script>
</head>
<body>
 
<table>
  <tr><td>First Row</td></tr>
  <tr><td>Middle Row</td></tr>
  <tr><td>Last Row</td></tr>
</table>
 
<script>
$( "tr:last" ).css({ backgroundColor: "yellow", fontWeight: "bolder" });
</script>
 
</body>
</html>
