关于Jquery ajax的问题

[MYsce]

请问有个json 数组 [ {name:"张三",Age:15},{name:"李四",Age:19} ]; 怎样使用jquery ajax 一次传递到服务器中！！求高手为菜鸟解答

类似的：

function submitForm() {
            var username = $("#username").val();
            var userpwd = $("#userpwd").val();
            if (username == "" || userpwd == "") {
                alert("请输入用户名或密码!");
                return false;
            }
            var json = '{"username":"' + username + '","userpwd":"' + userpwd + '"}';
            mini.mask({ el: document.body, cls: 'mini-mask-loading', html: '登录中...' });
            $.ajax({
                url: '@Url.Action("LoginValidate", "Home")',
                type: "post",
                data: { submitData: json },
                dataType: "text",
                success: function (res) {
                    if (res == "fail") {
                        alert("登录失败，请检查用户名及密码");
                        window.location.reload();
                    }
                    else window.location.href = '@Url.Action("Index", "Home")';
                }
            });
        }

[HttpPost]
        public string LoginValidate()
        {
            string submitData = Request["submitData"];
            JavaScriptSerializer serializer = new JavaScriptSerializer();
            LoginUser user = (LoginUser)serializer.Deserialize(submitData, typeof(LoginUser));
            using (userDAO as IDisposable)
            {
                bool flag = userDAO.LoginValidate(user.username.Trim(), Utils.Helper.StringToMD5Hash(user.userpwd.Trim()));
                if (flag)
                {
                    Session["login"] = "True";
                    Session["UserName"] = user.username.Trim();
                    return "success";
                }
                else
                {
                    return "fail";
                }
            }
        }

$.ajax({
            type: "POST",
            url: "",
            contentType: "application/json",
            dataType: "json",
            data: JSON.stringify({
                "Persons":[ {name:"张三",Age:15},{name:"李四",Age:19} ]

            }),
            success: function (data) {
                alert(data);
            }
        });

[HttpPost]
        public ActionResult (List<Person> Persons)
        {
            ;
        }

楼主想要什么效果？

[正怒月神]

$.ajax({ type: "post", url: "Handler1", dataType: "json", data: [ {name:"张三",Age:15},{name:"李四",Age:19} ], success: function (data) { alert("true"); } }); 后台 public string Handler1(List<User> u) {....} public class User { public string name{get;set;} public int Age{get;set;} }

你的后端是webform还是mvc? 你实在不知道怎么处理的话，就用js将json序列化成一个字符串然后向后端传递

[lescper2011]

作为参数一次传入就行。 不必指定每个参数。 或者说转换为字符串，作为一个参数传入，服务器再转换成json

[mirrorspace]

4楼代码就行 // $.post(url,{para:[ {name:"张三",Age:15},{name:"李四",Age:19} ]},function(data){ })

[平山CP3]

json.stringtify(json数组)传到服务器再解析
