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。
