Javascript 如何从对象数组中获取属性？

我在json响应中有一个对象数组，我想从

includeAssessmentList

数组中获取

riskAssessmentKey

，然后通过Post Api将该键传递到后端，我无法从该数组中获取属性。我怎样才能完成这项任务

到目前为止，我试过代码

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();
          });
        };

在

for

循环中，您只读取数组项，而不是所需的属性

风险评估键

。试试这个

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

如果必须从数组中读取所有ristAssetKeyKeys，请尝试此操作

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

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

var风险评估键=[]；
对于（var i=0；iThanks，我将使用您的第一个答案选项，因此在这里，一旦我获得riskAssessmentKey的列表，我想将所选的key从网格发送到post service，我如何使用第一个答案实现它。。。
   var riskAssessmentKeys = [];
   for (var i=0; i<assessmentKey.length; i++) {
      riskAssessmentKeys.push(assessmentKey[i].riskAssessmentKey);
   }
