The .fadeOut() method animates the opacity of the matched elements. Once the opacity reaches 0, the brandish fashion property is set to none, and so the chemical element no longer affects the layout of the page.

Durations are given in milliseconds; college values indicate slower animations, non faster ones. The strings 'fast' and 'slow' can be supplied to indicate durations of 200 and 600 milliseconds, respectively. If any other string is supplied, or if the duration parameter is omitted, the default duration of 400 milliseconds is used.

We tin animate whatever chemical element, such as a simple image:

1 2 3 four

<img id="book" src="volume.png" alt="" width="100" height="123">

With the chemical element initially shown, we can hide it slowly:

1 2 3 4 5

$( "#clickme" ).click( function() { $( "#book" ).fadeOut( "ho-hum", function() {

Annotation: To avoid unnecessary DOM manipulation, .fadeOut() will non hibernate an element that is already considered hidden. For information on which elements jQuery considers hidden, run into :hidden Selector.

Easing

As of jQuery one.four.three, an optional cord naming an easing role may exist used. Easing functions specify the speed at which the animation progresses at unlike points within the blitheness. The only easing implementations in the jQuery library are the default, called swing, and one that progresses at a constant pace, called linear. More easing functions are bachelor with the use of plug-ins, most notably the jQuery UI suite.

Callback Function

If supplied, the callback is fired once the animation is complete. This can exist useful for stringing different animations together in sequence. The callback is not sent any arguments, only this is set up to the DOM element being animated. If multiple elements are animated, it is important to note that the callback is executed in one case per matched element, not once for the animation every bit a whole.

As of jQuery one.half-dozen, the .promise() method tin can be used in conjunction with the deferred.done() method to execute a single callback for the animation as a whole when all matching elements have completed their animations ( See the example for .promise() ).

Additional Notes:

• All jQuery furnishings, including .fadeOut(), can exist turned off globally by setting jQuery.fx.off = true, which effectively sets the elapsing to 0. For more than information, meet jQuery.fx.off.

Examples:

Animates all paragraphs to fade out, completing the blitheness inside 600 milliseconds.
