Hello,
I am trying to get data from asp.net webservice to html.
Initially i have pre published webservice in my localhost, it returns a json formated string.
While retrieving json data from webservice, the browsers blocks response and shows a message:--->

Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at http://localhost:55619/WebService_DataCounter.asmx/Indus_Gadget_Data. This can be fixed by moving the resource to the same domain or enabling CORS. Indus_Gadget_Data.....

here is my code in webservice

C#

[WebMethod]
      public DataTable Indus_Gadget_Data()
      {
          dt = new DataTable();
          dt = process_indus_gadget_data.Indus_Gadget_Processing();
          dt.TableName = "All Sites data";
          System.Web.Script.Serialization.JavaScriptSerializer serializer = new System.Web.Script.Serialization.JavaScriptSerializer();
          List<overallstatics> details = new List<overallstatics>();
          details.Clear();
          if (dt.Rows.Count > 0 && dt != null)
          {
              foreach (DataRow dr in dt.Rows)
              {
                  OverallStatics user = new OverallStatics();
                  user.SiteName = dr[0].ToString();
                  user.EB = dr[1].ToString();
                  user.DG = dr[2].ToString();
                  user.LS = dr[3].ToString();
                  user.DC = dr[4].ToString();
                  details.Add(user);
              }
          }
         return serializer.Serialize(details);
      }

now in html data retrieving

HTML

<script type="text/javascript">
     document.onload = init();
     function init() {
         Get_Indus_Widget();
     }
     function Get_Indus_Widget() {
         $.ajax({
             type: "POST",
             url: "http://192.168.0.108:55619/WebService_DataCounter.asmx/Indus_Gadget_Data",
         // url: "WebService1.asmx/Indus_Gadget_Data",
             data: "{}",
             headers: { 'Access-Control-Allow-Origin': '*' },
             crossDomain: true,
             contentType: "application/json",
             dataType: "json",
             beforeSend: function (xhr) {
                 xhr.setRequestHeader("Access-Control-Allow-Origin", "*");
             },
             headers: {
                 'Access-Control-Allow-Origin': '*'},
            // jsonp: "mycallback",
             //crossDomain: true,
            // jsonpCallback: 'jsonCallback',
             success: function (data) {
                 for (var i = 0; i < data.d.length; i++) {
                     $("#tbDetails").append("<tr><td>" + data.d[i].SiteName + "</td><td>" + data.d[i].EB + "</td><td>" + data.d[i].DG + "</td><td>" + data.d[i].LS + "</td><td>" + data.d[i].DC + "</td></tr>");
                 }
             },
             error: function (result) {
                 alert("Error");
             }
         });
     }

I am getting the same error

XMLHttpRequest cannot load http://localhost:55619/WebService_DataCounter.asmx/Indus_Gadget_Data. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://localhost:56708' is therefore not allowed access.
