判断 IE ，Opera浏览器的类型，针对不同浏览器下多单元 元素事件或者样式的控制，比如td li等的控制。
<script language="javascript" type="text/javascript" >
var Fs_IsIE5 = (navigator.userAgent.indexOf("IE 5") > -1) || (navigator.userAgent.indexOf("IE 6") > -1);//导航的用户代理判断IE
var Fs_IsIE4 = document.all&&navigator.userAgent.indexOf("Opera")==-1//opera 判断
function InitColorPalette()
{
if (Fs_IsIE4)
{//Opera
var x = document.all.tags('td');
}
else
{//IE
var x = document.getElementsByTagName('td');
}
for (var i=4; i<x.length; i++)
{
x[i].onmouseover = over;
x[i].onmouseout = out;
x[i].onclick = click;
}
} ---------------------->相应的写js函数.

针对iframe的浏览器版本控制
<div>

onload="iframeResize(); scrollToTop();" frameborder="0" id="mainFrame" name="mainFrame"
src="XXX.aspx">您的浏览器不支持此功能，请您使用最新的版本。</iframe>
</div>
<script type="text/javascript">
<!--
if (window.addEventListener){//FF
window.addEventListener("load", iframeResize, false);//默认为false，强类型防止侦听器被回收
alert('window.addEventListener');
}
else
{
if (window.attachEvent){//IE
window.attachEvent("onload", iframeResize);
alert('window.attachEvent');
}
else{ //other
window.onload=iframeResize
alert('other');
}
}
-->
</script>
//IE FF下控制iframe的高度

dyniframe.height = dyniframe.contentDocument.body.scrollHeight + 10;}
