Re: javascript - wildcards

Thanks Jens,

I found that the "return" statement was hiding the result.

I looked up "regular expressions" in my three books and found nothing. A few days ago I didn't know that "replace" and "regular expressions" had anything to do with each other.

I found the "https://developer.mozilla.org/en/Core_JavaScript_1.5_Reference/Global_Objects/RegExp" very helpful.

What I'm after is for this line to remove all letters;

I have tried [a-z], {a-z}, "a-z".

You want:
elementValue = elementValue.replace(/[a-z]/ig, '')

Can't find any mention of this in my books or on the web.

There are entire books written about regular expressions :) I have one, although it's just the little "pocket guide" from O'Reilly.
And any _javascript_ book worth its salt should have at least a chapter on RE's.
Here's some documentation from mozilla's _javascript_ reference:
