here ajax code in i'm trying send request:

 var data;             $.ajax({                 type: "post",                 url: "register.aspx/getrecords",                 datatype: "json",                 success: function (response) {                     console.log(response.d);                     data = response;                 },                 error: function(xmlhttprequest, textstatus, errorthrown) {                  console.log("status: " + textstatus); console.log(" error: " + errorthrown);              }              });
