如何从对象数组中获取属性? [英] How to get property from an array of object ?

问题描述

我在json响应中有对象数组，我想从 includeAssessmentList 数组中获取 riskAssessmentKey 并将该键传递给Post Api后端，我无法获取数组中的属性.我该如何完成这项任务?

I have array of object in json response i want to get riskAssessmentKey from includeAssessmentList array and pass that key to backend through Post Api,I am not able to get the property from the array. How can i achieve that task ?

到目前为止尝试过的代码....

So far tried code....

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

推荐答案

在您的 for 循环中，您仅读取数组项，而不是必需的属性 riskAssessmentKey .试试这个.

In your for loop you are only reading the array item but not the required property riskAssessmentKey. Try this.

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

如果 includeAssessmentList 始终仅包含一项，则不需要for循环，您可以尝试此操作.

If includeAssessmentList always contains only one item then you don't need a for loop you can try this.

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

如果您必须从阵列中读取所有ristAssetKeyKeys，请尝试执行此操作.

If you have to read all the ristAssetKeyKeys from the array then try this.

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