Trapping errors in JavaScript or Calling CGIs

[TWTD]

Hi, first time posting so please be gentle!

I am running some scripts which exist on another server, and they may or may not exist at run-time. (A CGI will create the script later)

If it does not exist, IE ignores the error and continues processing, but Netscape does not. How can I make this happen?

The way I see it, I either need to trap the error, or call a cgi that creates a dummy JS file prior to the JS actually being called.

I am a complete novice at JavaScript, so I'd appreciate any advice.

Cheers

Gavin

do you ask for debug purpose or for error handling ??
to debug, use the javascript console with netscape, it's well done
to handle errors, it depends on which errors ...

Error handling unfortunately. If a script falls over, I would like to trap it.

then i'm afraid i can't help : i've never seen any error handling function in js - altough there must be some ??? i'm afraid that the errors are to be handled by the client's browser :-(

try try/catch blocks:

try
{
//some code
}
catch(e)
{
//something went wrong in try, so we will grab the error here
