jQuery Validate - regex for letters with accented letters (Czech)

Question

I created a custom jQuery Validate rule:

jQuery.validator.addMethod(
        "regex",
        function(value, element, regexp) {
            var re = new RegExp(regexp);
            return this.optional(element) || re.test(value);
        },
        "Please check your input."
    );

And now would need regex to match only letters (in any language, especial Czech)

I tried

regex: "/^\pL++$/uD"

regex: "^\w*(\s\w*)?$"

None of these work. What would be the correct regex?

That's because JS doesn't natively support unicode categories. You can take a look here for more info on this.

Alternatively you could specify a unicode character class with different ranges if you didn't need to know whether or not a unicode character was a "letter" or not. For example:

^[\u0000-\u024F]+$

would ensure the string contains only control characters and all forms of latin characters including all extensions. You can refer here for more characters and ranges.

The example you provided seems to return true also for numbers...? – user1049961 Apr 08 '14 at 20:10
It's just an example. Tailor the character class range to fit your needs by referencing the table. – tenub Apr 08 '14 at 21:24
