无法获取jQuery AJAX请求进行处理

Question

Hi I'm trying to do just a simple ajax call to a method in my code behind. 嗨，我正在尝试对我后面的代码中的方法进行简单的ajax调用。 At this point I'm just testing, so I'm keeping it as simple as possible, but it's always erroring. 在这一点上，我只是在测试，所以我将其保持尽可能的简单，但始终会出错。 I'm sure it's just a simple mistake, but I have no idea what to do. 我敢肯定这只是一个简单的错误，但我不知道该怎么办。 It seems really straight forward, and it should work, but when I click the button, it just pops up an alert saying "[object Object]". 看起来确实很简单，并且应该可以使用，但是当我单击按钮时，它会弹出一个警告，提示“ [object Object]”。 Here is my code, any help is greatly appreciated: 这是我的代码，非常感谢您的帮助：

Code Behind: 背后的代码：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Text;
using System.Text.RegularExpressions;
using System.Data.SqlClient;
using System.Web.Services;

namespace Program
{
    public partial class TestPage : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {
        }
        [WebMethod]
        public static string InsertData()
        {
            string retMessage = "ddd";
            return retMessage;

        }
    }
}

UPDATE UPDATE

Sorry everyone, turns out the issue was in my global.asax. 抱歉，每个人都发现问题出在我的global.asax中。 It was intercepting the ajax request, and messing everything up. 它正在拦截ajax请求，并弄乱了所有内容。 Once I made sure the HTTP was a GET in the asax file, it stopped killing my ajax request, and started working. 一旦确定HTTP是asax文件中的GET，它就停止杀死我的ajax请求，并开始工作。

Answer 1

In your javascript, you're calling InsertData as a POST 在您的JavaScript中，您将POST称为InsertData

Try 尝试

    [WebMethod]
    [HttpPost]
    public static JsonResult InsertData()
    {
        return Json(new { Message = "ddd" }, JsonRequestBehavior.AllowGet);

    }

And in your javascript, 在您的JavaScript中，

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

Answer 2

You can try this: 您可以尝试以下方法：

var dataToPost = "{ country:'" + 2 + "', amount:" + 4.02 + "}";

$.ajax({
    url: @Url.Action("PostAmount", "Deal")',
    type: "POST",
    dataType: 'json',
    data: dataToPost,
    cache: false,
    contentType: "application/jsonrequest; charset=utf-8",
    success: function (data) {
        alert("hi"+ data);
    }
});
