asp.net 웹 양식은 [의 WebMethod]

Question

나는 내 [의 WebMethod]에 문제가 있습니다.

[WebMethod] 
    [ScriptMethod(ResponseFormat = ResponseFormat.Json)] 
    public static List<Contract> PopulateDataByJquery(int pageNo, int noOfRecord) 
    { 
     System.Threading.Thread.Sleep(2000); 
     Entities4 db = new Entities4(); 
     List<Contract> data = new List<Contract>(); 
     int skip = (pageNo - 1) * noOfRecord; 
     data = db.Contracts.Include("PhysicalPerson").Include("Product").OrderBy(a => a.Id).Skip(skip).Take(noOfRecord).ToList(); 
     return data; 
    } 

내가 아약스 오류가 발생하면 제발 도와주세요! 어떻게 고쳐야할지 모르겠다.

Answer 1

당신은 당신의 Ajax 호출을 일부 변경을해야하고 WebMethod

function populateData(pageIndex) { 
        // populate data from database 
        $.ajax({ 
         url: "Docs.aspx/PopulateDataByJquery", 
         data: "{pageNo: pageIndex, noOfRecord: 7}", 
         type: "POST", 
         dataType: "json", 
         contentType: "application/json; charset=utf-8", 
         success: OnSuccess, 
         error: onError 
        }); 
       } 
       function OnSuccess(data) { 

        alert('good'); 
       } 
       function onError() { 
        alert('Failed!'); 
        $('#LoadingPanel').css('display', 'none'); 
       } 

변경하여 WebMethod

[WebMethod] 
    public static string PopulateDataByJquery(int pageNo, int noOfRecord) 
    { 
     System.Threading.Thread.Sleep(2000); 
     Entities4 db = new Entities4(); 
     List<Contract> data = new List<Contract>(); 
     int skip = (pageNo - 1) * noOfRecord; 
     data = db.Contracts.Include("PhysicalPerson").Include("Product").OrderBy(a => a.Id).Skip(skip).Take(noOfRecord).ToList(); 
     JavaScriptSerializer TheSerializer = new JavaScriptSerializer() 
     var TheJson = TheSerializer.Serialize(data); 
     // for this you need to add using System.Web.Script.Serialization; 
     return TheJson; 
    }
