Question

好的，我很难过。我有一个角度json GET进程，正如预期的那样提取结果，但我似乎无法解析并获得结果的单个值。

以下是我得到的字符串结果：

{"result":[{"sys_id":"f4425c21ec0970407e85e2a57ceff437","number":"INC0035062"}]}

这是我的代码：

$http({
 method:'GET',
 url:$scope.url,
 transformResponse: undefined}).then(function(response) {
  console.log(response.data);
}).catch(function(response) {
  console.error('Error', response.status, response.data);
})
.finally(function() {
  console.log("All Done");
});

那么，我怎样才能获得sys_id的单个值？

提前致谢， DP

*******编辑： Sajeetharan，仍有问题。根据您的示例更改了代码：

console.log(response.data);
  $scope.data = response.data.result; 
  console.log($scope.data);
  console.log("Sys id is:"+$scope.data[0].sys_id);

输出：

{"result":[{"sys_id":"f4425c21ec0970407e85e2a57ceff437","number":"INC0035062"}]}
undefined

Answer 1

如果您想访问sys_id，请访问数组的 0th index data ，

 $http.get('test.json').then(function(response){
      $scope.data = response.data.result;      
  });

如果要使用表达式访问sys_id，

在Html中

 <div ng-controller="ListCtrl">
   <h1> Sys id is :{{data[0].sys_id}} </h1>
  </div>

如果要使用控制器访问sys_id，

$http.get('test.json').then(function(response){
          $scope.data = response.data.result; 
          console.log("Sys id is:"+$scope.data[0].sys_id);     
      });

这是最终工作的，通过angular.fromJson：

//CALL TO REST SERVICES
//---------------------
$http({
 method:'GET',
 url:$scope.url,
 transformResponse: undefined}).then(function(response) {
  console.log(response.data);
  $scope.data = angular.fromJson(response.data); 
  console.log($scope.data['result'][0].sys_id);
}).catch(function(response) {
  console.error('Error', response.status, response.data);
})
.finally(function() {
  console.log("All Done");
});
