Question

我在json响应中有对象数组我想从riskAssessmentKey数组中获取includeAssessmentList并通过Post Api将该键传递给后端，我无法从数组中获取属性。我怎样才能完成这项任务？

到目前为止尝试过代码......

main.js

$scope.deleteAssess = function(){
          var assessmentKey = [];
          assessmentKey = $scope.rcsaCycleDTO.includeAssessmentList;
          for (var i=0; i<assessmentKey.length; i++) {
              var riskAssessmentKeys = assessmentKey[i];
              console.log(riskAssessmentKeys);
          }
          RcsaFactory.assessmentDetails(assessmentKey,$scope.rcsaCycleDTO.statusLookUpCode).then(function(){
            setConfirmationWinButtons(true, true, true);
            $scope.confirmationWin.open().center();
            $scope.confirmationWin.close();
          });
        };

JSON.js

在for循环中，您只读取数组项而不是必需属性riskAssessmentKey。试试这个。

for (var i=0; i<assessmentKey.length; i++) {
   var riskAssessmentKeys = assessmentKey[i].riskAssessmentKey;
   console.log(riskAssessmentKeys);
}

如果includeAssessmentList始终只包含一个项目，那么您不需要for循环就可以试试。

if ($scope.rcsaCycleDTO.includeAssessmentList && $scope.rcsaCycleDTO.includeAssessmentList.length) {
  var riskAssessmentKeys = $scope.rcsaCycleDTO.includeAssessmentList[0].riskAssessmentKey;
}

如果你必须从数组中读取所有ristAssetKeyKeys，那么试试这个。

   var riskAssessmentKeys = [];
   for (var i=0; i<assessmentKey.length; i++) {
      riskAssessmentKeys.push(assessmentKey[i].riskAssessmentKey);
   }

如何从一个对象数组中获取属性？
