Question

当我使用ajax调用Web服务时出现错误，我尝试搜索所有内容但我无法解决此问题。

下面是我的网络服务类

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Services;
using System.Web.Script.Services;
using System.Web.Script.Serialization;

/// <summary>
/// Summary description for WebServiceHome
/// </summary>
[WebService(Namespace = "http://tempuri.org/")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
// To allow this Web Service to be called from script, using ASP.NET AJAX, uncomment the following line. 
[System.ComponentModel.ToolboxItem(false)]
[System.Web.Script.Services.ScriptService]

public class WebServiceHome : System.Web.Services.WebService {

    public WebServiceHome () {

        //Uncomment the following line if using designed components 
        //InitializeComponent(); 
    }
    [WebMethod]
    public int converttodaysweb(int day, int month, int year)
    {
        DateTime dt = new DateTime(year, month, day);
        int datetodays = DateTime.Now.Subtract(dt).Days;
        return datetodays;

    }

    [System.Web.Script.Services.ScriptMethod()]
    [WebMethod]
    public string GetData()
    {
        Dictionary<string, string> name = new Dictionary<string, string>();
        name.Add("1", "Rashid");
        name.Add("2", "Burhan");
        string myJsonString = (new JavaScriptSerializer()).Serialize(name);

        return myJsonString;
    }

}

它可以正常使用调用按钮，但是当我尝试使用jquery ajax调用它时工作正常。

Invoke click button Image

但是当我尝试使用jquery ajax调用上面的方法时我得到了一些错误，下面是我的jquery ajax调用

var GetJson = function () {
            var requestdata = {};
            requestdata.id = "";
            var pdata = "";
            var Requrl = "http://localhost:51120/WebServiceNew/WebServiceHome.asmx/GetData";
            $.ajax({
                type: "POST",
                url: Requrl,
                crossDomain: true,
                contentType: "application/json",
                dataType: "json",
                success: function (data) {
                    alert(data);
                },
                error: function (xhr) {
                    console.log(xhr);
                }
            });
        }

我收到以下错误
