Validate first 4 characters using jQuery Validation plugin

Question

I don't know if this question has already been answer before. What I'm trying to do is validate an input text, but i need the length to be less than 10 characters and I need the 4 first characters to be Letters only and the rest only Numbers

how can i achieve this using the jQuery Validation Plugin?, i chose to use this plugin because it seems to be the easiest way

$("form").validate({
  rules: {
    myField: { lettersonly: true }
  }
});

To ensure the max lenth, use the maxlengh attribute.

If you nee to only check the first 4 characters for alpha ... roll your own.

doesn't solve problem of validating first 4 characters – charlietfl Oct 07 '17 at 19:01
Hence why I said "roll your own" ... the library doesn't support "first four characters". – Patrick Oct 07 '17 at 19:01
So how does this answer help then when it doesn't do what is asked? – charlietfl Oct 07 '17 at 19:02
It gets them started on alpha-only. Then the callback to handle the "first four". – Patrick Oct 07 '17 at 19:02
Considering that `lettersonly` is a custom method don't see how this helps at all and implies something that doesn't exist – charlietfl Oct 07 '17 at 19:08
