Notation: The event treatment suite likewise has a method named .toggle(). Which 1 is fired depends on the set of arguments passed.

With no parameters, the .toggle() method just toggles the visibility of elements:

The matched elements volition be revealed or hidden immediately, with no animation, by changing the CSS display property. If the element is initially displayed, it volition be hidden; if subconscious, it volition be shown. The brandish belongings is saved and restored as needed. If an element has a display value of inline, then is hidden and shown, it will once once again be displayed inline.

When a elapsing, a plain object, or a single "consummate" function is provided, .toggle() becomes an blitheness method. The .toggle() method animates the width, height, and opacity of the matched elements simultaneously. When these properties reach 0 after a hiding animation, the brandish style belongings is set up to none to ensure that the element no longer affects the layout of the folio.

Durations are given in milliseconds; higher values point slower animations, non faster ones. The strings 'fast' and 'slow' tin exist supplied to betoken durations of 200 and 600 milliseconds, respectively.

Equally of jQuery ane.4.three, an optional string naming an easing office may be used. Easing functions specify the speed at which the animation progresses at different points within the blitheness. The just easing implementations in the jQuery library are the default, called swing, and ane that progresses at a constant footstep, called linear. More than easing functions are available with the use of plug-ins, most notably the jQuery UI suite.

If supplied, the callback is fired once the blitheness is complete. This can be useful for stringing different animations together in sequence. The callback is not sent any arguments, but this is gear up 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, non once for the blitheness as a whole.

We can animate any element, such as a simple image:

1 2 iii 4

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

We will cause .toggle() to be called when some other chemical element is clicked:

one 2 3 iv five

$( "#clickme" ).click( function() { $( "#book" ).toggle( "slow", function() {

With the element initially shown, we can hide it slowly with the get-go click:

A 2nd click will show the chemical element once over again:

The second version of the method accepts a Boolean parameter. If this parameter is true, and so the matched elements are shown; if simulated, the elements are subconscious. In essence, the statement:

i	$( "#foo" ).toggle( display );

is equivalent to:

1 2 3 4 5

if ( display === true ) { } else if ( display === false ) {

Boosted Notes:

• All jQuery effects, including .toggle(), tin exist turned off globally past setting jQuery.fx.off = truthful, which finer sets the duration to 0. For more information, see jQuery.fx.off.
