UNIX for Dummies Questions & Answers

I need to transform this small javascript into a perl. So then when I need to use it I can call $something, instead of using this javascript.

Could someone help me archive this?

Why do you think Javascript can be rewritten into Perl? Javascript is executed by the client side (browser) while Perl code is executed at the server side. You can use Perl to generate Javascript (because that is just text) on the server side, but that is not using Perl to replace Javascript because they serve totally different purposes.

Ok, I see.
Is it not possible to create

if something print this
else print this?

The thing is that I am having a problem with old browser reading the javascript that I am executing from the cgi program.

I see that this will be a bigger problem then I that, so I will figure a
way around this problem.

Thanks anyway

Then that is a client-side Javascript problem. It has nothing to do with Perl even though Perl is used to generate the Javascript.

If what you want to do is to execute different bits of Javascript depending on condition. That is possible with Javascript alone. People are doing that all over the Web to address different browsers. Sometimes you may need to wrap the code in a try ... catch block to catch exceptions so that you can try several variations until finding one that works!

Of course, unless you have reasons to generate dynamic Javascript from Perl, moving all the javascript away from the HTML to a separate .js file that is sourced from the HTML esp. if you have lots of javascript. Then you can serve that JS file with Apache directly rather than wasting resources generating JS from Perl.

Correction; that other thread was closed by the moderator as a duplicate of this one.

Comment #2 in the other thread has some sort of answer (I hope).
