Question

我的班级;

public class Disciplines
{
    public int Id { get; set; }

    public string Name { get; set; }
}

我的控制员;

public void test (Disciplines discipline)
{

}

并使用ajax我想将参数发送给测试控制器。

我的javascript是;

    var disciplines = {Id:1, name:"white"};
            $.ajax({

                type: "POST",
                url: "test",
                data: { disciplines:disciplines },
                dataType: "Json",
                success: function (response) {
                },
                beforeSend: function () {


   showIndicator();
            },
            error: onFailure,

        });

当我调试它时，控制器参数始终为null。我怎么能成功地做到这一点。非常感谢。

您的代码应为

SELECT Datename(weekday, time)              AS weekday,
   ( ( Datepart(hour, time) / 3 ) - 3 ) AS segment,
   Count(*)                             AS num_transactions
FROM   "transaction"
GROUP  BY Datename(weekday, time),
          ( ( Datepart(hour, time) / 3 ) - 3 )
ORDER  BY CASE Datename(weekday, time)
            WHEN 'Monday' THEN 1
            WHEN 'Tuesday' THEN 2
            WHEN 'Wednesday' THEN 3
            WHEN 'Thursday' THEN 4
            WHEN 'Friday' THEN 5
            WHEN 'Saturday' THEN 6
            WHEN 'Sunday' THEN 7
          END,
          ( ( Datepart(hour, time) / 3 ) - 3 );

<强>控制器

 var disciplines = {"Id":1, "Name":"white"};

$.ajax({

                type: "POST",
                url: "test",
                data: { disciplines:disciplines },
                dataType: "Json",
                success: function (response) {
                },
                beforeSend: function () {


   showIndicator();
            },
            error: onFailure,

        });

必须具有与类

中相同的参数名称

问题是因为模型活页夹会在请求中查找name和disciplines属性，而不是var disciplines = { id: 1, name: "white" }; $.ajax({ type: "POST", url: "test", data: disciplines, dataType: "json", success: function (response) { }, beforeSend: function () { showIndicator(); }, error: onFailure, });。试试这个：

var str:String = 'Hello World!';
