Question

I have been given the task to apply regular expressions on a form validation which I have achieved (using jquery.validate.js). Now, I have to apply a type of regular expressions when the select tag is pointed to US and other type of regular expressions when is pointed to any other country. Any help will be fully appreciated. Thanks in advance.

If you’re using jquery.validate.js when you configure validate and add your rules, try something along the lines of (to add your own rule):

$('#myForm').validate({
    rules: {
        'myField': {
            myRule: function(element) {
                var option = element.find('option:selected');
                if (option.val() == 'US') {
                    return // The result of your US only regular expression check
                } else {
                    return // The result of your other regular expression check
                }
            }
        }
    }
});

Something like that should get you in the right direction if I understand your question correctly.
