Detecting browser help. Options

[Hefty]

I've been looking around for the exact code but cannot find it. What I want is a code that detects if the user is using Internet Explorer and if so then display an error message saying 'We detect you are using Internet explorer, part of the site may not be fully functional with your browser".

Please help.

You could use conditional comments: http://www.quirksmode.org/css/condcom.html or its javascript equivalent: http://www.javascriptkit.com/javatutors/co...alcompile.shtml

But if possible it's better to make a page or script degrade gracefully without bothering the user with warnings: http://www.quirksmode.org/js/support.html

You should also make sure the page works without any javascript.

Does this mean your site will be fully functional if I use, say, Netscape 4?

Or Opera or Firefox with all the bells and whistles disabled?

Or only some of them disabled?

if(navigator.appName=='Microsoft Internet Explorer')
{
alert('Get Firefox')
}

I would use browser detection to run a script that will fix the bugs in IE, not an error message saying the site won't work entirely. Since most people use IE, they aren't going to be happy the bells and whistles are disabled.
