Question

I have a javascript array variable that is created in an action => new form but I can’t seem to find a way to return this variable as a field to the controller along with the other form field inputs. How do I set this array to a hidden field in the form. Is there a way to pass the array back into the parameters hash to the controller?

$(document).ready(function() {

    arr = new Array();

        $(document).on('change', 'select[id ^="package"]', function() {
            var arr = $('select[id ^="package"]').map(function(){
                return this.value
            })          
        });

});

I have this javascript array and I want to submit the form with :packages set to the javascript variable arr.

If you have a hidden field already, you can do this in JavaScript:

$('#MODELNAME_packages').val(arr);
