如何使用AngularJS在工厂访问$ scope对象？

Question

I have serialize method for post , So riskAssessmentKey is not part of $scope.topRiskDTO but i pass the riskAssessmentKey value from $scope.riskAssessmentDTO.riskAssessmentkey and now i am posting to factory but when i save all values are posting but riskAssessmentKey is coming undefined i dont know why..

So far tried code....

parentCtrl.js

$scope.addTopRisk = function(){
              topRiskGridConfig.topRiskmodalWinConfig.title = 'Add top Risk';
              $scope.viewTopRiskWin.setOptions(topRiskGridConfig.topRiskmodalWinConfig);
              $scope.$broadcast('addTopRisk',$scope.riskAssessmentDTO.riskAssessmentKey);
            };

childCtrl.js

$scope.topRiskDTO = {};
  $scope.issuePltDataSource = kendoCustomDataSource.getDropDownDataSource('RA_KY_CNCRN_IS_PLTFM');
  $scope.$on('addTopRisk', function (s,id){
    $scope.riskAssessmentDTO.riskAssessmentKey = id;
    $scope.viewTopRiskWin.open().center();
    $scope.submit = function(){
      rcsaAssessmentFactory.saveTopRisk($scope.topRiskDTO,id).then(function(){
        $scope.viewTopRiskWin.close();
      });
    };
  });

factory.js

   var serializeTopRisk = function (topRisk,id) {
          var riskAssessmentKey = id;
          var objToReturn = {
              topRiskName: topRisk.topRiskName,
              mitigationActivityDes: topRisk.mitigationActivityDes,
              issuePltfLookUpCode: topRisk.issuePltfLookUpCode,
              issueNo: topRisk.issueNo,
              riskAssessmentKey: topRisk.riskAssessmentKey
          };

          if(topRisk.riskAssessmentKey){
            objToReturn.riskAssessmentKey = topRisk.riskAssessmentKey;
          }
          return objToReturn;
      };
         saveTopRisk: function(topRisk,id) {
                      var request = serializeTopRisk(topRisk);
                      console.log('request payload', JSON.stringify(request));
                      console.log('ID :: ', id);
                      var endpoint = 'app/assessment/rest/addTopRisks';
                      return $http.post(endpoint, request);


 }

You forgot to pass the id to the serializeTopRisk function.

So you already pass the params correctly this this:

saveTopRisk: function(topRisk,id) {
                  var request = serializeTopRisk(topRisk);

But then serializeTopRisk should also get the id

var serializeTopRisk = function (topRisk, id) { // added the id over what you originally had
          var riskAssessmentKey = $rootScope.riskAssessmentDTO.riskAssessmentKey; // drop this, use id instead

Don't use rootScope to pass data between the factory and the controller if you don't need to (it looks like you are already passing values to the factory from the controller by supplying it with object inputs, keep it that way and drop the rootScope usage from the factory).
