Have you looked at the jQuery.validate plugin?

$('#formid').validate({
    rules: {
        fieldname: {
            required:function(element) {
                return /^\s*[0-9]{,3}(?:\.[0-9]{1,3})?\s*$/.test(element.value);
            }
        }
    }
});

EDIT: admittedly I didn't test the regex and merely wanted to demonstrate how it works. Updated regex as per nickf's suggestion, thanks.
