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:
