ajax提交实体类参数的方法

页面JS代码
    function SaveVehicleManager() { var Name = $("#txtName").val();
        var Phone = $("#txtPhone").val(); 
        var IDCard = $("#txtIDCard").val();  


        var Param1 = JSON.stringify({ "Name": Name, "Phone": Phone, "IDCard": IDCard }); //必须转换为Json对象
        console.log(Param1) 
        console.log("调用接口 SaveVehicleManager:" )
        $.ajax({
            url: "/WeiXin/Register/SaveVehicleManager",
            type: "POST",
            contentType: "application/json",//必须要有
            data: Param1, 
            success: function (data) {
                console.log(data) 
                if (data == 1) {
                    alert("数据保存成功！")
                }
                else {
                    alert("数据保存失败！")
                }
            }
        });
    }

后台controller层方法
        [HttpPost]
        public ActionResult SaveVehicleManager(VehicleManagerModels vmm)
        {
            int Result = DBServices.SaveVehicleManager(vmm);

            return Json(Result);
        }

实体类定义
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;

namespace VehicleManage.Models
{
    public class VehicleManagerModels
    {
        public string Name { get; set; }
        public string Phone { get; set; }
        public string IDCard { get; set; } 
    }
}
