jQuery的ajax 方法提交多个对象数组问题 C# traditional $.param

var arr1=[{ "aa": "1", "bb": "2" }, { "aa": "3", "bb": "4"}];

var arr2=[{ "aa": "1", "bb": "2" }, { "aa": "3", "bb": "4"}];


function addUser(){

        $.ajax({
            url:'UserAdd',
            data:$.param(arr1.serializeObject("list1"))+"&"+$.param(arr2.serializeObject("list2"),    //手动把数据转换拼接
            type:'post',
            traditional:true,    //这里必须设置
            success:function(msg){
                if(msg=='1'){
                    console.log('添加成功');
                }else{
                    console.log('添加失败')
                }
            }
        });
    }

 

 后台接收：

public class Test
    {
        public int aa{ get; set; }
        public int bb{ get; set; }
    }

        public ActionResult UserAdd( List<Test> list1, List<Test> list2)
        {
            
            return Json(amm);
        }

jsonp

一般处理程序内

 　　　　public void ProcessRequest(HttpContext context)
        {
            context.Response.ContentType = "text/plain";
            string method = context.Request["Method"].ToString();

            string callback = context.Request.QueryString["callback"]; // 用于jsonP的跨域调用。

            MethodInfo methodInfo = this.GetType().GetMethod(method);//利用反射 获取方法
            string result = methodInfo.Invoke(this, null).ToString();//执行获取到的方法
            if (string.IsNullOrEmpty(callback))
            {
                context.Response.Write(result);
            }
            else
            {
                context.Response.Write(callback + "(" + result + ")");
            }
        }
