本文实例讲述了JS简单实现浮动窗口效果。分享给大家供大家参考，具体如下：

HTML部分：

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN""http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"><html xmlns="http://www.w3.org/1999/xhtml"><head><meta http-equiv="Content-Type" content="text/html; charset=utf-8" /><title>无标题文档</title><style type="text/css">*{ margin:0; padding:0;}a img{ border:0;}</style></head><body><div style="height:2000px; background:#ccc; display:none;"></div><!--div id="floatAd" style=" position:fixed !important; position:absolute; _top:expression(eval(document.documentElement.scrollTop+document.documentElement.clientHeight-this.offsetHeight)); z-index: 2147483647; left: 50%; margin-left: -240px !important; top: 50%; margin-top: -210px !important; background:url(images/onlineSay.jpg) no-repeat; width:487px; height:350px; cursor:pointer;"><div onclick="closeFAd();" style=" width:26px; height:26px; float:right;"></div><div style="width:487px; height:320px; float:right;" onclick="open_online();"></div></div><div id="floatSide" style=" width:141px; height:579px; position:fixed !important; position:absolute; _top:expression(eval(document.documentElement.scrollTop+document.documentElement.clientHeight-this.offsetHeight)); z-index: 99999; right:0; top:6%; background:url(images/onlineTel.gif);cursor:pointer;" onclick="open_online();></div--></body></html><script type="text/javascript" src="online.js"></script>

JS部分：

// JavaScript Document//浮动广告图片var floatAdImg = "images/onlineSay.jpg";//浮动侧栏图片var floatSideImg = "images/onlineTel.gif";//打开在线沟通function open_online(){ window.open('http://p.qiao.baidu.com//im/index?siteid=7342332&ucid=7601325');}//浮动广告document.writeln("<div id=/"floatAd/" style=/" position:fixed !important; position:absolute; _top:expression(eval(document.documentElement.scrollTop+document.documentElement.clientHeight-this.offsetHeight)); z-index: 2147483647; left: 50%; margin-left: -240px !important; top: 50%; margin-top: -210px !important; background:url("+floatAdImg+") no-repeat; width:487px; height:350px; cursor:pointer; display:none; /">");document.writeln("<div onclick=/"closeFAd();/" style=/" width:26px; height:26px; float:right;/"></div>");document.writeln("<div style=/"width:487px; height:320px; float:right;/" onclick=/"open_online();/"></div>");document.writeln("</div>");//浮动侧栏document.writeln("<div style=/" width:141px; height:579px; position:fixed !important; position:absolute; _top:expression(eval(document.documentElement.scrollTop+document.documentElement.clientHeight-this.offsetHeight)); z-index: 99999; right:0; top:6%; background:url("+floatSideImg+");cursor:pointer;/" onclick=/"open_online();/"></div>");//关闭浮动广告function closeFAd(){ document.getElementById('floatAd').style.display = 'none';}//打开浮动广告function showFAd(){ document.getElementById('floatAd').style.display = 'block';}//打开浮动窗口function showFloat(){ document.getElementById('floatAd').style.display = 'block';}//打开窗口 20 秒仅执行一次setTimeout(showFAd,20000);//每个 30 秒执行一次setInterval(showFloat,30000);

效果图如下：
