Селектор :even


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 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").
  • Selected elements are in the order of their appearance in the document.
