Re: Need advice on reliable way to identify IE as the browser

It'd get ugly because that'd mean the ActiveX menace has spread but you'd
still be targetting the same functionality. Beyond inaccurate user agent
strings, checking for the object you're trying to use also protects you from
changes between browsers in past and future versions.

You're welcome, Vern. Glad I could help.

Yeah, I don't do Opera although I'll sing just about anything.......

Could do

var isIE = navigator.userAgent.indexOf('MSIE') != -1 and
navigator.userAgent.indexOf('Opera') = -1;

But that could get tedious. I agree, Alfredo has a more elegant design
until someone builds a plugin that will run ActiveX in other browsers.
Then things will get ugly...

Problem there is that some browsers, like Opera, report themselves as

MSIE and also contain the word Opera in this attribute. I did not want
something so messy as to deal with a bunch of browsers, although I would
have gone that way. Alfredo, though, wins a Dr Pepper at the next COMMON.

User agent is what I have been using but I haven't had to deal with

Safari.

var isIE = navigator.userAgent.indexOf('MSIE') != -1;

Have a CGI app that builds a page with some Javascript - it can try to

I will

treat it as such.

I've looked at some ways to know that the browser is IE - UserAgent I

think is

one but things like Opera can make themselves look like IE for part of

it.

The use of the ActiveX object involves a javascript:void that calls a

function. That function tries to execute a function in the ActiveX

object. I

have tried a try-catch around the javascript:void but am seeing - doh -

that

there will never be an error at that point that I can respond to - or is

there?

In firefox, the call to the ActiveX function does generate an error,

but it's

buried in the javascript:void.

So what are my options? Back to useragent or whatever it's called? -

have to

check google again. Or is there a way to check some error back where I

use the

javascript:void?

Or something else!!

Thanks
