全屏浮动广告代码

把这个代码复制到一个新建的htm中就可以看到效果了


<div id="img" style="position:absolute;">


<a style="cursor:hand;" href="http://happy2008.yeepay.com/10027" target="_blank"><img src="images/tp.jpg"




width="210" height="100" border="0" onclick="javascript:window.hide()" /></a>


</div>

下面的部分可以放在一个js文件里面


<SCRIPT LANGUAGE="JavaScript">


function hide()




...{


img.style.visibility="hidden";


}


</script>




<SCRIPT LANGUAGE="JavaScript">
