<body>
<p style="height:2000px; background:#ccc; display:none;">
</p>
<!--p 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;">
<p onclick="closefad();" style=" width:26px; height:26px; float:right;"></p>
<p style="width:487px; height:320px; float:right;" onclick="open_online();"></p>
</p>
<p 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();></p-->
</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("<p 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("<p onclick=\"closefad();\" style=\" width:26px; height:26px; float:right;\"></p>");
document.writeln("<p style=\"width:487px; height:320px; float:right;\" onclick=\"open_online();\"></p>");
document.writeln("</p>");
//浮动侧栏
document.writeln("<p 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();\"></p>");
//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:
