regex in JS

OK, I have to take a variable and make it a filename

So in Perl I use a statement like:
$ttile="Words letters # 450 235&$*(_@";

$title =~ s|[^A-Z0-9]||gi;

$title has all the words and numbers only, no spaces or special characters.

I have done regex in JS, but only to test =~ m|something| equivilent

How do I do substitution in JS ?

a string object has a replace method that can be used with a regular expression

var title ="Words letters # 450 235&$*(_@";
var regEx = /[^A-Z0-9]/gi;
title = title.replace(regEx,"");

or if you want to do it on one line...

title = title.replace(/[^A-Z0-9]/gi,"");

For reference of anyone finding this thread, they can read about replace and other String methods here or to find out more about the RegExp object, they can go here.

Yes, google is always a good place to start. But when providing links for people to reference, linking to real content is better,

Well, if someone gets broken links, they can still google and won't be any worse off,
