Regex and jQuery: lower case

Question

I would like to validate my form with jquery validation plugin. I added a method for on input:

$.validator.addMethod("testRegex", function(value, element) {
    return this.optional(element) || /^[a-z0-9-_]+$/i.test(value);
}, "test must contain only letters, numbers, underscores or dashes");

But I want a validation to check if the value is only lowercase. And This validation doesn't work.

Do you have an idea?

As an aside, if you're only going to allow lowercase your error message should say that too. — nnnnnn, Oct 05 '13 at 16:39

The i in your regex means ignore case. If you want your regular expression to be case sensitive then remove it.

/^[a-z0-9-_]+$/i

becomes

/^[a-z0-9-_]+$/

No i at end.
