这篇文章主要介绍了JQuery特殊效果和链式调用操作,结合实例形式分析总结了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.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。
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。
