使用AngularJs如何编写成功和失败的代码

Question

如何在AngularCtrl中应用成功并失败

JSONArray arr = jobObject.getJSONArray("MultipleChoices");

Answer 1

我所理解的是，您正在询问如何处理承诺返回成功/失败，就像您从$ http请求服务获得的那样，所以下面是一个示例：

$http.get('http://freegeoip.net/json')
.success(function (data, status, headers, config) {
    //TODO When request Success
    console.log(data);
    $scope.Employee = data;
})
.error(function (data, status, headers, config) {
    //TODO When request Failed
    console.log(data); //Server Response values if there's any
    $scope.Employee = [];
});

Answer 2

这是一个可以帮助您的示例代码。

  $scope.Btncall = function () {
      MyService.GetDatafromApi().success(function (data, status,headers)    
      {
        $scope.Employee = data;
      })
      .error(function (data, status, headers) {
         $scope.Employee = [];
      });
    }

//Call Btncall Function..
$scope.Btncall();
