I have a web site that uses MSN Live Maps. It works in Opera if I
change the User Agent to IE. Is there a way to change the User Agent
via Javascript for one page?
Find whatever variable is used to store the user agent (usually
something like var IE = true/false) and just set it to true. But I
expect that will break much more than it fixes.
From the little I have seen of MS Live Maps, I wouldn't use it for a
web site. It uses extensive browser sniffing and requires the
download of a 750kB script file. In another thread, I did a search
for the string "attachEvent" and got 234 hits whereas addEventListener
only rated 11 - seems to me it is deliberately designed to provide
more features for IE than any other browser.
Now that is fine, MS are quite at liberty to create IE-specific web
libraries, but if you want a site that works well in other browsers,
don't use it.

I understand what you are saying but MS live maps is a requirement of
a project I am doing. I figured it out and posting results:
if (browser.indexOf("Opera") >= 0 )
{
navigator.userAgent="Mozilla/5.0 (compatible; MSIE 7.0; Windows NT
5.2)";
}
Easy Peazy

Are you testing to make sure "Opera" is in the string here? Yes. But
you're not testing for the false value String.indexOf will give you back
reliably, which is -1. That line should really be:
if (browser.indexOf("Opera") != -1 )
In this case it doesn't hurt you, but it's a good practice, and will
make your code more readable, IMHO.
As var as the code itself:
<script type="text/javascript">
var browser = navigator.userAgent;
if (browser.indexOf("Opera") >= 0 )
{
navigator.userAgent="Mozilla/5.0 (compatible; MSIE 7.0; Windows NT5.2)";
}
document.write (navigator.userAgent);// Firefox writes:
Mozilla/5.0 (Windows; U; Windows NT 6.0; en-US; rv:1.8.1.11)
Gecko/20071127 Firefox/2.0.0.11
// IE7 writes:

</script>
So it appears to me from the actual tests that you can't modify it. This
works for you? I would be careful with the assumption that it will
continue to do so. IMHO, of course.

Interesting. I plugged the above javascript on my sitehttp://njection.com/speedtrap
and it works just fine. Tried it on several versions of Opera.

Not really.

Oddly enough, that browser wasn't among the test cases.
So it works on Opera and virtually nothing else (and may throw an
exception in some agents.) Regardless, it's a completely ridiculous
thing to do.
BTW, some versions of Opera allow the user to change the userAgent
string to eliminate the "Opera" portion. This is one of many reasons
that browser sniffing cannot be relied upon.
