返回值:jQueryslideUp([speed,[easing],[fn]])

概述

通过高度变化(向上减小)来动态地隐藏所有匹配的元素,在隐藏完成后可选地触发一个回调函数。

这个动画效果只调整元素的高度,可以使匹配的元素以“滑动”的方式隐藏起来。在jQuery 1.3中,上下的padding和margin也会有动画,效果更流畅。

参数

speed[,fn]Number/String,FunctionV1.0

speed:三种预定速度之一的字符串("slow","normal", or "fast")或表示动画时长的毫秒数值(如:1000)

fn:在动画完成时执行的函数,每个元素执行一次。

[speed],[easing],[fn]Number/String,String,FunctionV1.4.3

speed:三种预定速度之一的字符串("slow","normal", or "fast")或表示动画时长的毫秒数值(如:1000)

easing:(Optional) 用来指定切换效果,默认是"swing",可用参数"linear"

fn:在动画完成时执行的函数,每个元素执行一次。

示例

描述:

用600毫秒缓慢的将段落滑上

jQuery 代码:
$("p").slideUp("slow");

描述:

用200毫秒快速将段落滑上,之后弹出一个对话框

jQuery 代码:
$("p").slideUp("fast",function(){
   alert("Animation Done.");
 });
