Question

我正在尝试根据“帐户持有人姓氏”显示帐户记录。此帐户持有人姓氏来自输入文本。这是一个通过wcf服务获取操作来检索用户帐户信息。但是当我输入帐户持有人姓氏并点击提交按钮时，问题就是它没有显示任何内容。我调试应用程序，我收到错误消息丢失主机未定义。

这是Angular JS Code。

问题解决了，我不得不改变这行代码。

$scope.Search = function () {
          var post = $http({
              method: "GET",
              url: "http://localhost:52098/HalifaxIISService.svc/GetCustomers/" + encodeURIComponent($scope.Account_Holder_Last_Name),
              dataType: 'json',
              headers: {
                  'Accept': 'application/json, text/javascript, */*; q=0.01',
                  'Content-Type': 'application/json; charset=utf-8'
              }
          });

          post.then(function (response) { // .success(function(data => .then(function(response
              var data = response.data; // extract data from resposne
              $scope.Customers = JSON.parse(data); // eval(data.d) => JSON.parse(data)
              $scope.IsVisible = true;
          }, function (err) {
              $window.alert(err);
          });
}
