:odd Selector

odd selector

version added: 1.0jQuery(':odd')

Description: Selects odd elements, zero-indexed. See also even.

In particular, note that the 0-based indexing means that, counter-intuitively, :odd selects the second element, fourth element, and so on within the matched set.

Example:

Finds odd table rows, matching the second, fourth and so on (index 1, 3, 5 etc.).

<!DOCTYPE html>
<html>
<head>
  <style>

  table {
    background:#f3f7f5;
  }
  </style>
  <script src="http://code.jquery.com/jquery-latest.js"></script>
</head>
<body>
	<table border="1">
    <tr><td>Row with Index #0</td></tr>
    <tr><td>Row with Index #1</td></tr>

    <tr><td>Row with Index #2</td></tr>
    <tr><td>Row with Index #3</td></tr>
  </table>
<script>$("tr:odd").css("background-color", "#bbbbff");</script>
</body>
</html>
