even selector
Description: Selects even elements, zero-indexed. See also odd.
jQuery(':even')
version added: 1.0
In particular, note that the 0-based indexing means that, counter-intuitively, :even selects the first element, third element, and so on within the matched set.
Examples
Finds even table rows, matching the first, third and so on (index 0, 2, 4 etc.).Full source:
<!DOCTYPE html> <html> <head> <script src="http://code.jquery.com/jquery-latest.js"></script> <script> $(document).ready(function(){ $("tr:even").css("background-color", "#bbbbff"); }); </script> <style> table { background:#eeeeee; } </style> </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> </body> </html>
