使用大量数据给出x.support.cors.e.crossDomain.send错误 [英] giving x.support.cors.e.crossDomain.send error with large amount of data

问题描述

我的aspx代码页面中有一个webmethod用于获取员工每日报告，我通过AJAX和JSON将结果绑定到表中..



我的问题当我选择单个员工并通过AJAX获取其数据时，它可以正常工作，但当我选择所有员工（126），这给我输出大约4000条记录时，它给我错误

I have one webmethod in my aspx code behind page for getting employees daily report, i am binding that result into table through AJAX and JSON..

My problem is when i select single employee and get its data through AJAX it works properly , but when i select all employees (126) which gives me output of around 4000 records it gives me error of

x.support.cors.e.crossDomain.send

我的ajax是：

my ajax is :

$.ajax({
   type: "POST",
   data: params,
   url: "../Sales/AdminDARReport.aspx/GetDARReport",
   contentType: "application/json; charset=utf-8",
   dataType: "json",
   success: function (res) {
      console.log(res.d);
      // alert(res.d.length);
   },error:function(res,msg,code){}
});

我的webmethod是：

My webmethod is :

[WebMethod]
public static List<DARReport> GetDARReport(string darfor, string employeeid, string fromdate, string todate)
{
   List<DARReport> dr = new List<DARReport>();
   try
   {
      SQLDataAccessHelper sq = new SQLDataAccessHelper();
      SqlParameter[] param = new SqlParameter[3];
      param[0]=new SqlParameter("@fromdate_o", SqlDbType.NVarChar);
      param[0].Value = fromdate;
      param[1] = new SqlParameter("@todate_o", SqlDbType.NVarChar);
      param[1].Value = todate;
      param[2] = new SqlParameter("@userid", SqlDbType.NVarChar);
      param[2].Value = employeeid;
      DataSet ds = new DataSet();
      if (darfor.ToLower() == "reagent")
      {
         ds = sq.ExecuteDataSet("usp_admin_reagent_report", param);
         if ((ds != null) && (ds.Tables.Count != 0) && (ds.Tables[0].Rows.Count != 0))
         {
            ds.Tables[0].TableName = "DARREAGENT";

            for (int i = 0; i < ds.Tables[0].Rows.Count - 1; i++)
            {
               dr.Add(new DARReport {
                  dardate =ds.Tables [0].Rows[i]["DARDATE"].ToString (),
                  placeofwork = ds.Tables[0].Rows[i]["PLACEOFWORK"].ToString(),
                  reagentcall = ds.Tables[0].Rows[i]["REAGENTCALL"].ToString(),
                  instrumentcall = ds.Tables[0].Rows[i]["INSTRUMENTCALL"].ToString(),
                  jointvisitwith = ds.Tables[0].Rows[i]["JOINTVISITWITH"].ToString(),
                  pobvalue = ds.Tables[0].Rows[i]["POB"].ToString(),
                  remarks= ds.Tables[0].Rows[i]["REMARKS"].ToString(),
                  employeename= ds.Tables[0].Rows[i]["USERNAME"].ToString()
               });
            }
            dr.Add(new DARReport {
               averagereagentcall = ds.Tables[0].Rows[ds.Tables[0].Rows.Count - 1]["AVERAGECALLS"].ToString(),
               averagepob = ds.Tables[0].Rows[ds.Tables[0].Rows.Count - 1]["AVERAGEPOB"].ToString()
             });
         }
      }
   }
   catch (Exception ex) { throw ex; }
   finally { }
   return dr;
}

i刚刚对记录返回的数量做了警告，但是当数据很大时，它也没有提供计数警报...



请在这种情况下帮助我..

推荐答案

.ajax（{
type： POST，
data： params ，
url： ../ Sales / AdminDARReport.aspx / GetDARReport，
contentType： application / json ; charset = utf-8，
dataType： json，
成功：函数（res）{
console.log（res.d）;
// alert（res.d.length）;
}，错误：函数（res，msg，代码）{}
}）;

.ajax({ type: "POST", data: params, url: "../Sales/AdminDARReport.aspx/GetDARReport", contentType: "application/json; charset=utf-8", dataType: "json", success: function (res) { console.log(res.d); // alert(res.d.length); },error:function(res,msg,code){} });
