:even ** DEPRECATED **S2C Home « Selectors « :even
Even index selector.
Shorthand version $(':even')
Description
The :even selector, selects even elements within the matched set.
- Like all the positional selectors
:evenuses a zero-based index to select from previously filtered elements. - Being a jQuery extension the
:evenpseudo selector is not part of any current CSS specification. Therefore:evencannot take advantage of the performance boost provided by the native DOMquerySelectorAll()method. - The same results can be achieved with better performance using the
:evenmethod with a valid CSS selector, for example$('.testtable td').even().css('backgroundColor', 'purple');.
This method was deprecated in jQuery 3.4.
