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

这里将是数据的内容：

data[from] = "bfleming@test.com"
data[to] = "test@test.com"
data[message] = "testmessage"

jQuery的：

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;
}
