Spaces in Jquery Validation Regex

Question

Basically what i am trying to do is validate a form. In one of the fields i want to allow spaces:

I've been using:

$.validator.addMethod(
    "legalname",
    function(value, element) {
        return this.optional(element) || /^[a-zA-Z0-9()._-\s]+$/.test(value);
    },
    "Illegal character. Only points, spaces, underscores or dashes are allowed."
);

$("#editform").validate({
    rules: {
        name: {
            required: true,
            legalname: true
        },
    });

This works in Safari, but not in Firefox where it gives me a "invalid range in character class". Any ideas how i can get this working?

Escape that dash. Within a character class it defines a character range. — Ray Toal

You're missing a } on the validate(), and older versions of IE can flip out over trailing commas like the one below name:. — Jared Farrish

Or the OP could put the dash at the end. Interesting about it "working in Safari," eh? — Ray Toal

@gdoron it's safe to put the dash at the beginning or end of a character class, Sections 15.10.1 and 15.10.2 of the ECMAScript 5 spec define how it works. But good point about it being risky in the sense of a possible later modification shifting its position. Best to explicitly escape the dashes and right brackets at all times, perhaps. — Ray Toal

Try escaping the -: As you can see here: Working demo: http://jsfiddle.net/svp6D/2

/^[a-zA-Z0-9()._\-\s]+$/

Characters that need to be escaped inside characters class ([]) are:

- \ / [] ^

I don't know how the rest of you feel, but I find regular-expressions.info a good resource.
