这篇文章主要介绍了JQuery特殊效果和链式调用操作,结合实例形式分析了jQuery各种常见显示效果与所使用的函数,以及链式调用显示层级菜单功能相关操作技巧,需要的朋友可以参考下

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./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-层级菜单

链式调用

level1的下一级淡入淡出，返回上一级的，孩子隐藏。

感兴趣的朋友可以使用在线HTML/CSS/JavaScript代码运行工具 测试上述代码运行效果。
