adding a javascript array to the post variables

adding a javascript array to the post variables

I am catching a submit in jquery, performing a check and submitting the form if the check passes.  If the check passes, I would also like attach a javascript array I have created to the post variables that get sent to the PHP page.  Here is the code I have so far.  All I am missing is attaching the array.
  1. $('form').submit(function(e) {
                    var barcodes = new Array();
                    $('.highlighted').each(function(i, obj) {
                        var barcode = $(':nth-child(2)', $(this)).html();
                        barcodes.push(barcode);
                    });
                    if(barcodes.length !== 0) {
                        console.log('barcodes is not empty!');






  2.                     // attach barcodes to post array
                        return true;
                    } else {
                        return false;
                    }
                });




Thanks
