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 = { };

arr should be declared as an object inside ArrayPush method because you are not using it like an array. Also inside the function you can just use this.id and this.value you don't have to create the jQuery object. Try this

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