Browser Detection Javascript

Hello ... You may tired of searching javascript for browser detection. For your best use i've given below very neat javascript.

<script type="text/javascript">
var browsername = navigator.appName;
var browserversion = navigator.appVersion;
var browserdetail = browsername+browserversion;
if (browserdetail.indexOf(' ')!=-1)
{
alert(its working!);
}
</script>

Inside indexOf(''), you can mention the browser name with version (e.g. MSIE 6.0).

thank you ... bye
