:animated Selector

Categories: Selectors > Basic Filter | Selectors > jQuery Extensions

animated selector

Description: Select all elements that are in the progress of an animation at the time the selector is run.

  • version added: 1.2jQuery( ":animated" )

Note: If you use a custom jQuery build without the effects module, the :animated selector will throw an error.

Additional Notes:

  • Because :animated is a jQuery extension and not part of the CSS specification, queries using :animated cannot take advantage of the performance boost provided by the native DOM querySelectorAll() method. To achieve the best performance when using :animated to select elements, first select the elements using a pure CSS selector, then use .filter(":animated").

Example:

Change the color of any div that is animated.
