:odd Selector
Categories: jQuery Extensions | Basic Filter
jQuery(':odd')
Description: Selects odd elements, zero-indexed. See also even.
-
jQuery(':odd')
version added: 1.0
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.
Note:
Because:odd
is a jQuery extension and not part of the CSS specification, queries using :odd
cannot take advantage of the performance boost provided by the native DOM querySelectorAll()
method. To achieve the best performance when using :odd
to select elements, first select the elements using a pure CSS selector, then use .filter(":odd")
.
Note:
Selected elements are in the order of their appearance in the document.-
Finds odd table rows, matching the second, fourth and so on (index 1, 3, 5 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:#f3f7f5; }
Code:
$("tr:odd").css("background-color", "#bbbbff");
