Javascript Regular Expression

[mjclark91]

Hey all. I'm having some trouble with a regular expression.

I'm trying to allow lbackspaces, lowercase letters, numbers, and dashes.

Here it is:

 var AllowRegex  = /^[\ba-z0-9-]$/;

I'm testing it as such:

AllowRegex.test(character)

For some reason it's not working. It only functions when I use it like this (which isn't the way I want it) : var AllowRegex = /^[\ba-zA-Z0-9-]$/;


Can someone help me get to where I need to be?

Thanks in advance!

Mike.
