.fadeOut()
Hide the matched elements by fading them to transparent.
.fadeOut(duration, complete)π‘’ jQuery
duration
Number, String Default: 400
complete
Function A function to call once the animation is complete, called once per matched element..fadeOut(options)π‘’ jQuery
options
PlainObject A map of additional options to pass to the method.
duration
Number, String, Boolean, String Default: 400
easing
String Default: swing
queue
Number, String, Boolean, String Default: true
.dequeue("queuename") to start it.
specialEasing
PlainObject An object containing one or more of the CSS properties defined by the properties argument and their corresponding easing functions.
step
Function A function to be called for each animated property of each animated element. This function provides an opportunity to modify the Tween object to change the value of the property before it is set.
progress
Function A function to be called after each step of the animation, only once per animated element regardless of the number of animated properties.
complete
Function A function that is called once the animation on an element is complete.
start
Function A function to call when the animation on an element begins.
done
Function A function to be called when the animation on an element completes (its Promise object is resolved).
fail
Function A function to be called when the animation on an element fails to complete (its Promise object is rejected).
always
Function A function to be called when the animation on an element completes or stops without completing (its Promise object is either resolved or rejected)..fadeOut(duration, easing, complete)π‘’ jQuery
duration
Number, String Default: 400
easing
String Default: swing
complete
Function A function to call once the animation is complete, called once per matched element.The .fadeOut() method animates the opacity of the matched elements. Once the opacity reaches 0, the display style property is set to none, so the element no longer affects the layout of the page.
Durations are given in milliseconds; higher values indicate slower animations, not 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 can animate any element, such as a simple image:
<div id="clickme">Click here</div>
<img id="book" src="book.png" alt="" width="100" height="123" />
With the element initially shown, we can hide it slowly:
$("#clickme").click(function () {
$("#book").fadeOut("slow", function () {
// Animation complete.
});
});
fadeOut() effectNote: To avoid unnecessary DOM manipulation, .fadeOut() will not hide an element that is already considered hidden. For information on which elements jQuery considers hidden, see :hidden Selector.
Easing
As of jQuery 1.4.3, an optional string naming an easing function may be used. Easing functions specify the speed at which the animation progresses at different points within the animation. 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 available 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 be useful for stringing different animations together in sequence. The callback is not sent any arguments, but this is set to the DOM element being animated. If multiple elements are animated, it is important to note that the callback is executed once per matched element, not once for the animation as a whole.
As of jQuery 1.6, the .promise() method 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() ).
Animates all paragraphs to fade out, completing the animation within 600 milliseconds.
<p>If you click on this paragraph you'll see it just fade away.</p>
p {
font-size: 150%;
cursor: pointer;
}
$("p").click(function () {
$("p").fadeOut("slow");
});

Fades out two divs, one with a "linear" easing and one with the default, "swing," easing.
