even selector
Описание: Selects even elements, zero-indexed. See also odd.
Добавлен в версии: 1.0jQuery( ":even" )
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.
Дополнительные замечания:
-
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 DOMquerySelectorAll()
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")
. - Selected elements are in the order of their appearance in the document.
