:even Selector
Categories: jQuery Extensions | Basic Filter
jQuery(':even')
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.
Note:
Because:even
is a jQuery extension and not part of the CSS specification, queries using :even
cannot take advantage of the performance boost provided by the native DOM querySelectorAll()
method. To achieve the best performance when using :even
to select elements, first select the elements using a pure CSS selector, then use .filter(":even")
.
Note:
Selected elements are in the order of their appearance in the document.-
Finds even table rows, matching the first, third and so on (index 0, 2, 4 etc.).
HTML:
<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>
CSS:
table { background:#eeeeee; }
Code:
$("tr:even").css("background-color", "#bbbbff");
