JS判断当前的浏览器类型

<script type="text/javascript">

//window.navigator.userAgent.indexOf("MSIE")>=1   为ie浏览器。
//window.navigator.appName.indexOf("Microsoft") != -1  为ie浏览器。
//window.navigator.userAgent.indexOf("MSIE 6.0")>0  判断是否为ie6
//window.navigator.appVersion.match(/6./i)=="6."  判断是否为ie6

if (window.navigator.userAgent.indexOf("MSIE")>=1){
<%@include file='/common/jsp/footer_ie.jsp'%>
}else if(window.navigator.userAgent.indexOf("Firefox")>=1){
<%@include file='/common/jsp/footer_firefox.jsp'%>
}else if(window.navigator.userAgent.indexOf("Chrome")>=1){
<%@include file='/common/jsp/footer_chrome.jsp'%>
}
</script>
