JQuery特殊效果和链式调用操作示例

时间：2021-05-26

本文实例讲述了JQuery特殊效果和链式调用操作。分享给大家供大家参考，具体如下：

JQuery的特殊效果

fadeOut()淡入
fadeToggle()切换淡入淡出
hide() 隐藏元素
show() 现实元素
toggle() 切换元素的可见状态
slideDown() 向下展开
slideUp() 向上卷起
slideToggle()依次展开或者卷起某个元素

<!DOCTYPE html><html lang="en"><head> <meta charset="UTF-8"> <title>Title</title> <style type="text/css"> .box{ width: 300px; height: 300px; background-color: gold; display: none; } </style> <script src="http://libs.baidu.com/jquery/2.0.0/jquery.min.js"></script> <script> $(function () { $('#btn').click(function () { $('.box').fadeIn(1000,'swing',function () { //可以加一个回调函数 alert('done'); }); }) }) </script></head><body><input type="button" name="" value="动画" id="btn"> <div class="box"></div></body></html>

点击按钮，元素淡出，完成之后弹出done，不知道为什么，没有运行出来，可能是浏览器的问题。

链式调用：

level1的下一级淡入淡出，返回上一级的，孩子隐藏。
