<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>漂浮回顶部按钮</title>
<style>
body{

}
</style>
<script>
<!--拖动滚动条或滚动鼠标轮-->
window.onscroll=function(){
if(document.body.scrollTop||document.documentElement.scrollTop>0){
document.getElementById('rTop').style.display="block"
}else{
document.getElementById('rTop').style.display="none"
}
}

document.getElementById('rTop').style.display="none"
}
</script>
</head>
<body>
<div class="rTop" id="rTop" onClick="toTop()">返回顶部</div>
