[Felipe Messina]

I wanna a KeyPressEvent that fills a text field with a mask like this(999,9999).
I have to do this, using regular expression.

Can someone help me?

thanks

Felipe:

What have you tried so far? What errors or exceptions are you getting? Remember, JavaRanch is not a code mill.

I did this

  function validar(v) {   
            
    v=v.replace(/\D/g,"");                    v=v.substring(0,6);
    v=v.replace(/(\d{1,3})(\d)/,"$1,$2");       
    return v;
    }    

But this way, let me put only 2 digits after the "," and I HAVE to have 3 digits before and 4 after.

Felipe:

What language are you using?

Looks like Javascript. Java and Javascript are *not* the same thing. Anyway, moving this to the JS forum.

I know that isnt the same, but I didnt find the JavaScript forum.
