Differentiate between IE4 & IE5

I am very new to javascript.
I just couldn't figure out a way to differentiate between the two.

The navigator.appVersion gives me 4.0 for both IE4 and IE5

Please Help !!

Yeah I discovered this as well and its very annoying. The way around it is to do this -

function checkBrowser(){
var version
if ((navigator.appVersion.substring(22,23) == "4") && (navigator.appName=="Microsoft Internet Explorer")){
version="IE4"; //IE4

}else{
version="Other"; //IE5
}
}

This is because the difference in version number is in the middle of the very long number string, not at the start.

Hope this helps.

Matt.

function checkBrowser(){
this.ver=navigator.appVersion;
this.dom=document.getElementById?1:0;
this.ie5=(this.ver.indexOf("MSIE 5")>-1 && this.dom)?1:0;
this.ie4=(document.all && !this.dom)?1:0;
this.ns5=(this.dom && parseInt(this.ver) >= 5) ?1:0;
this.ns4=(document.layers && !this.dom)?1:0;
this.B=(this.ie5 | | this.ie4 | | this.ns4 | | this.ns5);
return this
}
B=new checkBrowser();


this detects ie5 and ns6 via the dom,
to use it you would test for
if(B.ie4) - or if(B.dom) for ie5 etc
