MVC中处理Json和JS中处理Json对象

MVC中处理Json和JS中处理Json对象

ASP.NET MVC 很好的封装了Json,本文介绍MVC中处理Json和JS中处理Json对象,并提供详细的示例代码供参考。

MVC中已经很好的封装了Json,让我们很方便的进行操作,而不像JS中那么复杂了。

JsonResult 传值

MVC中:

 public JsonResult Test()
{
  JsonResult json = new JsonResult{ Data = new{ Name = "zzl", Sex = "male",} }; // Name、Sex为可自定义的属性名
  return Json(json);
}
public JsonResult TestList() { List<User> userList = new List<User> { new User{Name="zzl",Email="bfyxzls@sina.com"}, new User{Name="zhz",Email="zhanghangzheng@sina.com"}, }; JsonResult json = new JsonResult{ Data = userList };        return Json(json); }

 

前台调用:

 <script>

    $.ajax({
        url: "/Home/Test",
        dataType: "json",
        cache: false,
        data: null,
        type: "POST",
        success: function (data) {
            alert(data.Data.Name);
        }
    });
     $.ajax({
        url: "/Home/TestList",
        dataType: "json",
        cache: false,
        data: null,
        type: "POST",
        success: function (data) {
            var msg = "";
            for (var i = 0, length = data.Data.length; i < length; i++) {
        msg += "<DiV>Name:" + data.Data[i].Name + ",Email:" + data.Data[i].Email + "</div>";

            }
            $("#msg2").html(msg);
        }
    });
 </script>

 

直接传值

 public JsonResult Test()
{
  var json = new{ Name = "zzl", Sex = "male",} };
  return Json(json);
}
 public JsonResult TestList()

        {
            List<User> userList = new List<User>
            {
              new User{Name="zzl",Email="bfyxzls@sina.com"},
              new User{Name="zhz",Email="zhanghangzheng@sina.com"},
            };
      return Json(userList);

}

jq

$.ajax({
        url: "/Home/TestList",
        dataType: "json",
        cache: false,
        data: null,
        type: "POST",
        success: function (data) {
            var msg = "<table border=1><thead><tr><td>Name</td><td>Email</td></tr></thead><tbody>";
            for (var i = 0, length = data.length; i < length; i++) {
                msg += "<tr><td>" + data[i].Name + "</td><td>" 
                    + data[i].Email + "</td></tr>";
            }
            msg += "</body></table>";
            $("#msg2").html(msg);
        }
});

 

纯JS进行操作:

  var arr = [{ "name": "zzl", "sex": "男" }, { "name": "lr", "sex": "女"}];
   for (var i = 0; i < arr.length;i++ ) {
            document.write(arr[i].name);
        }
