function isIECore() {
    var boo = true;
     
    try{
        new ActiveXObject("Microsoft.XMLHTTP");
    }catch(e) {
        boo = false;
    }
    return boo;
}
alert(getType());
 </script>





或者下面的写法


<script language="JavaScript">

<!--

function getOs() {

var OsObject = "";

if(navigator.userAgent.indexOf("MSIE")>0) {

return "MSIE";

}

if(isFirefox=navigator.userAgent.indexOf("Firefox")>0){

return "Firefox";

}

if(isSafari=navigator.userAgent.indexOf("Safari")>0) {

return "Safari";

}

if(isCamino=navigator.userAgent.indexOf("Camino")>0){

return "Camino";

}

if(isMozilla=navigator.userAgent.indexOf("Gecko/")>0){

return "Gecko";

}

 

}

alert("您的浏览器类型为:"+getOs());

-->

</script>
