Javascript to redirect to browser friendly browser

Why do you want to do browser sniffing? It's a problematic, antiquated practice.

What about other browsers like Safari, Konqueror, and iCab?

By the way, navigator.appName is set to "Netscape" in Firefox. (That's because Firefox and Netscape 6-7 use various versions of the Mozilla Gecko engine.)

Also, it's set to "Opera" in Opera. You are doing a case-sensitive check there.

I took care of what i think were some problems in the script but still can not get it to work.

                       
         
           
           
             <script language="JavaScript" 
type="text/JavaScript">
if(navigator.appName == "Firefox")
{
 window.location = "myfirepage.html"
}
 if(navigator.appName == "Netscape")
{
 window.location = "mynetscapepage.html"
}
 if(navigator.appName == "Opera")
{
 window.location = "myoperapage.html"
}
 window.location == "myiepage.html"
</script>
<style type = "text/css">

greta13,

I really suggest you take a look at some info on the web about browser detection scripts like this before proceeding.

http://www.quirksmode.org/js/support.html
http://www.quirksmode.org/js/detect.html
http://www.quirksmode.org/blog/archives/2006/07/browser_detect.html - (part 2 of the link above updated to be more current)

I'll be happy to answer questions or help but those pages are REALLY worth looking at if you are considering something like this. There are scripts there you can use too but it may make you rethink this.

Let me know if you have any questions or need more information.

greta13,

By the way ... if you use a server script then that may be a better way to do this. Let us know what server technology or scripts your server supports or you can use.

User-agent sniffing is just as bad with a server-side language as it is with JavaScript.

QuirksMode.org is an excellent resource.

Here are two other similar articles:

>> User-agent sniffing is just as bad with a server-side language as it is with JavaScript. <<

I realize my last post may have been misleading on this point. I agree that server script doesn't change the reasons to avoid this. When I said "better way" I just meant if it had to be done then it was better for the server to do it. Of course depending on what you are testing for doing it with Javascript may be best and a very good thing to do (i.e. object detection in your script to use the object).

What is the code trying to use this info for? The idea is you don't just get the browser type but you use that type of script to work with how browsers handle something differently (or don't support it). What are you trying to do unique for Firefox?

for a redirect to a page that is specifically built for firefox...since firefox is not used by the public like ie is ...ie has a bigger market share..i built a page that will direct viewers of my page to firefox if they are using firefox...another words they view my page from firefox...then script say hey this guy has firefox i will load firefox page so the guy can see a page that displays better in firefox...that is what i am doing.

Are you not aware that there are techniques for making one page that looks the same (within reason) in most browsers, including IE, Firefox, and Safari?

Doing that happens to be one of my specialties. (If that sentence is considered advertising or solicitation please remove it without removing the question.)

My solution for loading specific pages (like css for firefox and html tables for opera) could be avoided by swapping content on the same page as oppossed to my antiquated solution of swapping complete pages or configuring redirects for each browser. So all of the web page content is on one page and by "detecting" which browser is viewing (is this stil the same problem?) The browser would simply parse
frendly content?

What is that code or what specifically are you trying to get to work or avoid in Firefox? Firefox is the second most popular browser so it is good that you are concerned about compatible code. Knowing what you are trying to do will hopefully help us find some way to do that in script. The change you are making is good ("parsing friendly content") but that is usually what is used to distinguish the browsers.

If for some reason you can't provide details then let us know.

Not quite. The code would be rewritten to be cross-browser compatible and CSS filters would be used where needed to deal with IE issues. For the most part Firefox, Safari, and Opera will display things the same. (Any JavaScript used might need to be modified as well. Obviously I can't tell without looking at it.)

@b0lsc0tt

I think greta13's last comment is in reply to my last comment.

At this point i haven't determine the hangs across browser but I am trying to weight the issue...and give it due diligence..browser sniffing was an important excercise because I am learning what javascript can do and it limitations..I was surprise to run into the firefox string = netscape string problem and I was also given some good links from which to investigate the plus and minus of my approach to picking off browsers. For right now I want to be able to write code that will properly id firefox and respond accordingly..thats next until done
thanks for your help

navigator.userAgent can be used. (I should mention that many browsers allow you to change the values of the properties of the navigator object, so it's not completely reliable.)

                       
             if(navigator.userAgent.indexOf('Firefox')!=-1)
