.slideUp()


.slideUp( [duration ] [, complete ] )Возвращает: jQuery

Описание: Hide the matched elements with a sliding motion.

  • Добавлен в версии: 1.0.slideUp( [duration ] [, complete ] )

    • duration (default: 400)
      Тип: Number or String
      A string or number determining how long the animation will run.
    • complete
      Тип: Function()
      A function to call once the animation is complete, called once per matched element.
  • Добавлен в версии: 1.0.slideUp( options )

    • options
      Тип: PlainObject
      A map of additional options to pass to the method.
      • duration (default: 400)
        Тип: Number or String
        A string or number determining how long the animation will run.
      • easing (default: swing)
        Тип: String
        A string indicating which easing function to use for the transition.
      • queue (default: true)
        Тип: Boolean or String
        A Boolean indicating whether to place the animation in the effects queue. If false, the animation will begin immediately. As of jQuery 1.7, the queue option can also accept a string, in which case the animation is added to the queue represented by that string. When a custom queue name is used the animation does not automatically start; you must call .dequeue("queuename") to start it.
      • specialEasing
        Тип: PlainObject
        An object containing one or more of the CSS properties defined by the properties argument and their corresponding easing functions. (Добавлен в версии: 1.4)
      • step
        Тип: Function( Number now, Tween tween )
        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
        Тип: Function( Promise animation, Number progress, Number remainingMs )
        A function to be called after each step of the animation, only once per animated element regardless of the number of animated properties. (Добавлен в версии: 1.8)
      • complete
        Тип: Function()
        A function that is called once the animation on an element is complete.
      • start
        Тип: Function( Promise animation )
        A function to call when the animation on an element begins. (Добавлен в версии: 1.8)
      • done
        Тип: Function( Promise animation, Boolean jumpedToEnd )
        A function to be called when the animation on an element completes (its Promise object is resolved). (Добавлен в версии: 1.8)
      • fail
        Тип: Function( Promise animation, Boolean jumpedToEnd )
        A function to be called when the animation on an element fails to complete (its Promise object is rejected). (Добавлен в версии: 1.8)
      • always
        Тип: Function( Promise animation, Boolean jumpedToEnd )
        A function to be called when the animation on an element completes or stops without completing (its Promise object is either resolved or rejected). (Добавлен в версии: 1.8)
  • Добавлен в версии: 1.4.3.slideUp( [duration ] [, easing ] [, complete ] )

    • duration (default: 400)
      Тип: Number or String
      A string or number determining how long the animation will run.
    • easing (default: swing)
      Тип: String
      A string indicating which easing function to use for the transition.
    • complete
      Тип: Function()
      A function to call once the animation is complete, called once per matched element.

The .slideUp() method animates the height of the matched elements. This causes lower parts of the page to slide up, appearing to conceal the items. Once the height reaches 0 (or, if set, to whatever the CSS min-height property is), the display style property is set to none to ensure that 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:

1
2
3
4
<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:

1
2
3
4
5
$( "#clickme" ).click(function() {
$( "#book" ).slideUp( "slow", function() {
// Animation complete.
});
});

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() ).

Дополнительные замечания:

  • All jQuery effects, including .slideUp(), can be turned off globally by setting jQuery.fx.off = true, which effectively sets the duration to 0. For more information, see jQuery.fx.off.
  • If .slideDown() is called on an unordered list (<ul>) and its <li> elements have position (relative, absolute, or fixed), the effect may not work properly in IE6 through at least IE9 unless the <ul> has "layout." To remedy the problem, add the position: relative; and zoom: 1; CSS declarations to the ul.

Animates all divs to slide up, completing the animation within 400 milliseconds.
