Checking textbox value against javascript array

Question

I have a quick question and I feel like I might just be missing something easy.

I currently have an array of codes below the document ready function of my jquery

    $(document).ready(function() { 
var code = ['code', 'code', 'code', 'code', 'code', 'code', 'code', 'code', 'code', 'code', 'code', 'code', 'code', 'code', 'code', 'HG3BV', 'code', 'code', 'code', 'code', 'code', 'code'];
"use strict";

This is at the top of my js document.

Then down further I check on my forms if it finds a class value of validate-required2 and if it does, I want it to check the value of the textbox #codes against my array.

            $(form).find('.validate-required2').each(function() {
            var cheater = $('#codes').val();
              if (jQuery.inArray(cheater, code)!='-1') {
                $(this).removeClass('field-error');
            } else {
                $(this).addClass('field-error');
                error = 1;
            }
        });

However this is constantly returning that the values aren't in the array. Did I miss something easy here?

put your code array declaration outside $(document).ready, before it. — Amit.rk3

You probably meant to write

var cheater = $(this).val();

if the selector '.validate-required2' refers to your input-elements. Your original selector can only get you one value in total since the id referred to ('#codes') must be unique on your page.

I actually just forgot to change the id on my input box to codes which was a really dumb thing of me to do but your answer works too!
