jquery 

$(document).ready(function () { $("#btnlogin").click(function () {     var uid = $("#txtun").attr('value');     var pass = $("#txtpwd").attr('value');     $.ajax({         type: "post",         url: "login.aspx/loginser",         data: '{un: ' + uid + ', pwd: ' + pass + '}',         contenttype: "application/json; charset=utf-8",         datatype: "json",         success: function (data) {             if (data.d == "1")             {                 window.location.assign("../../home.aspx");             }         },         error: function (xmlhttprequest, textstatus, errorthrown) {             //alert(xmlhttprequest.responsetext);             var err = eval("(" + xmlhttprequest.responsetext + ")");             alert(err.message);         }      });  }); });

i think url in ajax call incorrect. need provide service name, such login.asmx, , not page (i.e. login.aspx).

i not sure way passing data, may correct though.
