闲来无事，
分享几个jQuery简单实用的效果案例
不喜勿喷...
1、页面常用的返回顶部
<!DOCTYPE html>

<title>返回顶部</title>
<style type="text/css">
*{
margin: 0;

</style>
</head>
<body>
<div class="wrap">
<a href="###" class="gotop">TOP</a>
</div>
<script type="text/javascript" src="jquery-1.11.3.min.js"></script>
<script type="text/javascript">
$(function(){
// 当滚动条滚动大于200时出现，未大于，消失
$(window).scroll(function(){
if($(document).scrollTop()<200){
// alert("kk");
$(".gotop").stop().animate({ opacity: 0 },1000)
}
else{
$(".gotop").show().stop().animate({ opacity: 1 },1000)
}
})
// 返回顶部
$(".gotop").on("click",function(){
$("html,body").animate({
scrollTop:0
