Please help with browser detection 2

sql99 · Feb 14, 2005

Hello everyone,

Can someone please tell me how to write javascript code to detect if the user is using the IE browser? If they are, to continue w/the code. If not, to display an error message = "Your browser is not supported".

Thanks in advance for your help.

Hi,
Create a function using something like
this as a start:

Code:

function WhatBrowser(){
var strUA = "<%=Request.ServerVariables("HTTP_USER_AGENT") %>"
 if (strUA.indexOf("IE") > 1) {
//This means IE is the Browser
}
else {
//Put message here
}
} // end of function

Hope it helps..

Thank you for your reply, Turkbear...I should have posted my current code along w/the first thread. This is basically what I have...It's just a simple html file (below)...Can you please help me redirect with my exising code? I would like for users to get routed to the

http://www.test.com/main

page if they're using IE, otherwise, I would like a pop-up box to come up saying that their browser isn't supported. Thanks in advance for your help...

</head>

<body>
<H1>If you do not get automatically routed to the page, please click <a href="

http://www.test.com/main/">here</a></h1>

</body>

add this to the head of your document, and remove that <meta> tag.

Code:

<script type='text/javascript'>
if (navigator.appName.toLowerCase().indexOf("microsoft") != -1) {document.location.href="[URL unfurl="true"]http://www.test.com/main";}[/URL]
else {alert('Browser not supported');}
</script>

If this is a professional website you're doing, it's VERY poor practice to not write your page to support the major browsers. It's not hard to do, either, though you might have to forego some of the cutesy stuff that IE has built in. Firefox is coming on stronger all the time, so you're going to be excluding a growing share of the visitors to your site if you do this.

Thanks everyone for your help. I tried what eligidito suggested and it worked....There's just one more thing I'd like to ask. Is there anyway to prevent the <H1> tag from coming up for ppl who do not use IE? I would just like the pop-up window to display but not the <H1> tag. The <H1> tag is however needed for IE browsers.

Thanks again,

Here you go:

Code:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">

<html>
<head>
<script type='text/javascript'>
function isIE()
{
if (navigator.appName.toLowerCase().indexOf("microsoft") != -1) {
document.location.href = "[URL unfurl="true"]http://test.com/main";[/URL] 
return true;
}
else {alert('Browser not supported'); return false;}
}
isIE();
</script>

        <title>Untitled</title>
</head>

<body onLoad='if(isIE()){document.getElementById("hSpan").style.display="block";}'>
<H1 style="display:none" id="hSpan">If you do not get automatically routed to the page, please click <a href="[URL unfurl="true"]http://www.test.com/main/">here</a></h1>[/URL]
</body>
</html>

hope that does it
