從jquery中的C＃文件後面的代碼獲取數據

我想使用jquery和ajax從我的.aspx頁面中的C＃文件後面的代碼中獲取數據。但是我得到了解析錯誤，函數沒有調用。從jquery中的C＃文件後面的代碼獲取數據

$.ajax({ 
     type: "GET", 
     url: "/Pages/Maps.aspx/getTitles", 
     contentType: "application/json; charset=utf-8", 
     data: { }, 
     dataType: "json", 

      error: function (XMLHttpRequest, textStatus, errorThrown) { 
       alert("Request: " + XMLHttpRequest.toString() + "\n\nStatus: " + textStatus + "\n\nError: " + errorThrown); 
      }, 
      success: function (msg) { 
       alert(msg)} }); 

and function is 
[WebMethod] 
    public static string[] getTitles() 
      { 
       SPListItemCollection obj = RAK.DAL.DAL.GetSPListItemCollection("", "Map", null, 0, true, true); 
       SPQuery query = new SPQuery(); 

       string[] titles = new string[100]; 
       int count = 0; 
       foreach (SPListItem item in obj) 
       { 
        titles[count]= item["Title"].ToString(); 
        count++; 
       } 
       return titles; 
      }

但是我得到了parseerror。

仍然得到錯誤

你缺少[WebMethod]方法之前（您需要添加命名空間System.Web.Services.WebMethod）

using System.Web.Services.WebMethod 

[WebMethod] 
public static string[] getTitles() 
      { 
       SPListItemCollection obj = RAK.DAL.DAL.GetSPListItemCollection("", "Map", null, 0, true, true); 
       SPQuery query = new SPQuery(); 

       string[] titles = new string[100]; 
       int count = 0; 
       foreach (SPListItem item in obj) 
       { 
        titles[count]= item["Title"].ToString(); 
        count++; 
       } 
       return titles; 
      }
