json添加和删除数据

贴一段实例代码，不在过多介绍

        //{"F_DepartmentId":"8684502a-5dc2-487c-b589-48d2eb7734c1","F_ManagerId":"feige"}        var postData = $(".form").GetWebControls(keyValue);        var did = postData["F_DepartmentId"];        var mid = postData["F_ManagerId"];        //删除原来的json值        delete postData["F_DepartmentId"];        delete postData["F_ManagerId"];        //添加新的json值        postData["F_DealDepartMent"] = did;        postData["F_DealPerson"] = mid;        alert(JSON.stringify(postData));        //输出的结果是：{"F_DealDepartMent":"8684502a-5dc2-487c-b589-48d2eb7734c1","F_DealPerson":"feige"}
