wildcard in jquery value

Question

Sorry if this question is silly, Please feel free to correct.

I am using the code below for a form validation. How can I use a wildcard so that flagL12, flagM52 and other form ids starting with flag are validated?

var flag = $('#flag').val();
    if(!new RegExp("^[0-9]{2}$").test(flag)){
        $('#require-msg').html("FLAG format invalid! <br>Only 2 digit Numbers allowed for FLAG");
        $('#modal_opener').click();
        e.preventDefault();
        return false;
    }

I tried using ^ after flag but it does not work

    var flag = $('#flag^').val();
    if(!new RegExp("^[0-9]{2}$").test(flag)){
        $('#require-msg').html("FLAG format invalid! <br>Only 2 digit Numbers allowed for FLAG");
        $('#modal_opener').click();
        e.preventDefault();
        return false;
    }

The attribute startsWith selector is: `$('[id^=flag]')` but your other code doesn't really make sense so you should provide a minimalistic sample replicating your issue. You would probably use: `if($('[id^=flag]').filter(function(){return !new RegExp("^[0-9]{2}$").test(this.value)}).length) {$('#require-msg').html("FLAG format invalid!
Only 2 digit Numbers allowed for FLAG");}` — A. Wolff, Jun 24 '16 at 08:27

You can use,

$("[id^='flag']")

This will select all the elements whose id starts with 'flag'
