passing an array to json.stringify

Question

I'm trying to pass an array to json.stringify but the returned value is coming back empty.

JSON.stringify({ json: data }) // returns `{"json":[]}`

And here would be the contents of data:

data[from] = "[email protected]"
data[to] = "[email protected]"
data[message] = "testmessage"

jquery:

function SubmitUserInformation($group) {
    var data = {};
    data = ArrayPush($group);
    $.ajax({
        type: "POST",
        url: "http://www.mlaglobal.com/components/handlers/FormRequestHandler.aspx/EmailFormRequestHandler",
        data: JSON.stringify({ json: data }),
        dataType: 'json',
        contentType: "application/json; charset=utf-8",
        cache: false,
        success: function (msg) {
            if (msg) {
                $('emailForm-content').hide();
                $('emailForm-thankyou').show();
            }
        },
        error: function (msg) {
            form.data("validator").invalidate(msg);
        }
    });
}

function ArrayPush($group) {
    var arr = new Array();
    $group.find('input[type=text],textarea').each(function () {
        arr[$(this).attr('id')] = $(this).val();
    });
    return arr;
}

data = ArrayPush($group);

Is re-assigning data to be an array, so all your expando properties are not being stringified.

Inside your ArrayPush method, change

var arr = new Array();

to

var obj = { };
