Detailed explanation of jQuery.slideToggle() function usage

slideToggle() function is used to switch all matching elements with sliding transition animation effect.

The so-called "switch" means that if the element is currently visible, hide it (slide up); if the element is currently hidden, make it appear (slide down).

This function belongs to the jQuery object (instance).

Syntax

This function is new in jQuery 1.0. The slideToggle() function mainly has the following two forms of usage:

Usage 1: jQuery 1.4.3 newly supports parameter easing.

jQueryObject.slideToggle( [ duration ] [, easing ] [, complete ] )

Usage 2:

jQueryObject.slideToggle( options )

Usage The second is a variation of usage one. Specify the required option parameters in object form (you can specify more option parameters than Usage 1).

Parameters

Parameter Description

duration Optional/String/Number type specifies how long the transition animation runs (number of milliseconds), the default value is 400. This parameter can also be a string"fast"(=200) or "slow"(=600).

easing Optional/String type specifies which animation effect to use, the default is "swing", and can also be set to "linear" or other custom animation style function names.

complete Function that needs to be executed after the optional/Function type element is displayed. This within the function points to the current DOM element.

options Object classType specified option parameter object.

The parameter options object can recognize the following attributes (the following attributes are optional):

Attribute Attribute description

duration See parameter duration.

easing See parameter easing.

complete See parameter complete.

queue Boolean type indicates whether to put the animation into the effect queue, the default is true. Starting from version 1.7, this parameter can be a string, which is used to put into the effect queue with the specified name. If the queue you specify does not start automatically, you need to manually call dequeue("queueName") to start the queue.

In addition, jQuery 1.4 and 1.8 also added many new option support for parameter options, but these parameters are not commonly used and will not be described here. For details, see the jQuery official documentation.
