Problem with DTHML Browser detection/redirection

[mjance]

I'm trying to get this DHTML browser detection redirection script to work for
MSIE browsers >= 6 and Netscape Browsers >= 6. I am using MSIE 6 and Netscape 7.1 to test
these scripts under these conditions.

This is the original script, which is to be placed in the head section of the html document:

<script>

//Browser redirect Script- Dynamic Drive (www.dynamicdrive.com)
//For full source code, 100's more DHTML scripts, and Terms Of Use,
//visit dynamicdrive.com

var browser_type=navigator.appName
var browser_version=parseInt(navigator.appVersion)

//if NS 6
if (browser_type=="Netscape"&&browser_version>=5)
window.location.replace("http://mozilla.org")
//if IE 4+
else if (browser_type=="Microsoft Internet Explorer"&&browser_version>=4)
window.location.replace("http://microsoft.com")
//if NS4+
else if (browser_type=="Netscape"&&browser_version>=4)
window.location.replace("http://www.netscape.com")
//Default goto page (NOT NS 4+ and NOT IE 4+)
else
window.location="http://www.dynamicdrive.com"
</script>






This actually works. But when I change it to this...

<script>

//Browser redirect Script- Dynamic Drive (www.dynamicdrive.com)
//For full source code, 100's more DHTML scripts, and Terms Of Use,
//visit dynamicdrive.com

var browser_type=navigator.appName
var browser_version=parseInt(navigator.appVersion)

//if NS 6
if (browser_type=="Netscape"&&browser_version>=6) // Changed from >=5 to >= 6
window.location.replace("http://mozilla.org")
//if IE 4+
else if (browser_type=="Microsoft Internet Explorer"&&browser_version>=6) // Changed from >=4 to >=6
window.location.replace("http://microsoft.com")
//if NS4+
else if (browser_type=="Netscape"&&browser_version>=4)
window.location.replace("http://www.netscape.com")
//Default goto page (NOT NS 4+ and NOT IE 4+)
else
window.location="http://www.dynamicdrive.com"
</script>




... The first test condition goes to www.netscape.com (not mozilla.org) and the second test condition goes to the last condition (dynamicdrive.com)


Am I doing something wrong here? How do I get Netscape browsers >=6 and MSIE browsers >= 6 to go to the specified locations?


Thanks!

Although you tested it with NS7.1, if you add the following line of code, you will see that your browser version is still version 5. This is why your script is not responding as you expect.

Code: Select all

var browser_type=navigator.appName
var browser_version=parseInt(navigator.appVersion)

alert(browser_type + "\n" + browser_version) // Add this line

Good reason! Is that because of the happy people over at netscape then?? How can you detect for their browser when it won't tell you it's real version??

It's relatively basic as browser-sniffing goes. Try something a little more involved, or just write the code suitable for any browser.
