miniUI的异步请求

    // 保存按钮单击事件
        function onSave() {
            var obj = form.getData(true);
            form.validate();
            if (form.isValid() == false) return;
            var data = mini.encode(obj);
            $.ajax({
                url: "@Url.Action("SaveSealedManagementData")",
                data: data,
                type: "post",
                dataType: "json",
                contentType: "application/json",
                success: function (result) {
                    if (result) {
                        CloseOwnerWindow("save");
                    } else {
                        mini.alert("数据保存失败，请重试！");
                    }
                },
                error: function (jqXHR, textStatus, errorThrown) {
                    alert(jqXHR.responseText);
                }
            });
        }

mini encode之后就必须加  dataType: "json",
                contentType: "application/json",这样后台的mvc才会自动识别否别不会自动识别

 dataType: "json",这是返回数据的类型不用加
                contentType: "application/json",这是请求过去的数据的类型必须加
