##jQuery.hide () Detailed explanation of function

hide()

If the element itself is invisible, no changes are made to it. If the element is visible, hide it.

Relative to this function is the show() function, which is used to

display all matching elements

. This function belongs to the jQuery object (instance).

Syntax

jQuery 1.0 Added this function. hide()

The function mainly has the following two forms of usage:

Usage 1: jQuery

1.4.3 Added support parameter

easing.

jQueryObject.hide( [ duration ] [, easing ] [, complete ] )
Usage Two:

jQueryObject.hide( options )
Usage Two is a variation of Usage One. Specify the required option parameters in object form (you can specify more option parameters than Usage 1).

Parameters


##Parameters

Description##Optional/String/Number type specifies transition How long to run the animation in milliseconds. The default value is 400. This parameter can also be a ##Optional/String type specifies which animation effect to use, default It can be set to "swing", or it can also be set to "linear" or Optional/Function type element needs to be executed after hiding . this within the function points to the current DOM element. ##Object class The option parameter object specified by type .

如果没有为hide()指定任何参数,则将以最快方式直接隐藏元素,不使用动画效果。

参数options对象可以识别如下的属性(以下属性均是可选的):

duration
string

"fast"(=200) or "slow"(=600).

easing

The function name of other customized animation styles.

swing: swing effect (swing), slow on both sides and fast in the middle. linear: linear

complete

options
属性 属性描述
duration 参见参数duration
easing 参见参数easing
complete 参见参数complete
queue

Boolean类型指示是否将动画放入效果队列中,默认为true。从1.7版本开始,

该参数可以为字符串,用于放入指定名称的效果队列。如果你指定的队列不会自动开始,

你需要手动调用dequeue("queueName")来启动队列。

此外,jQuery 1.4 和 1.8 还为参数options新增了许多新的选项支持,但这些参数并不常用,此处不再赘述,详见jQuery官方文档。

返回值

hide()函数的返回值jQuery类型,返回当前jQuery对象本身。
