Question

Read EDIT 2 at bottom
Original post:

I have this jQuery validator method to check for a valid YYYY-MM-DD date:

$.validator.addMethod("myDate", function(value, element){

    var validformat = /^\d\d\d\d\-(0[1-9]|1[012])\-(0[1-9]|[12][0-9]|3[01])$/;
    return validformat.test(value);

}, "Please enter a valid YYYY-MM-DD date");

It works fine on my computer – returns false when expected and true when expected. However, on my Android phone it always returns false – the input always says “Please enter a valid YYYY-MM-DD date” even when the date is valid.

Do any regex methods such as .test() work differently on Android (and possibly other phones), or is this a jQuery Validator bug?

EDIT: I have tried changing validformat.test(value) to value.match(validformat) with the same result – works on computer, not on phone.

EDIT 2: Ok even commenting everything else out inside the method and typing return true; still yields the error on my phone. Definitely a jQuery validator problem. Need a workaround though!

Answer 1

I have just checked on an Android 2.3 phone. It works perfectly.

Therefore, I blame it on Android 2.2 only. So here’s my little fix:

$("#myform").validate({
...
    <?php
    //only print out the rule into the JS if it's not Android 2.2
    if(!strpos($_SERVER['HTTP_USER_AGENT'], "Android 2.2"))
        print "myDate: true, \n";
    ?>

Annoying hacks 🙂
