Angularjs Call Directive Function From The Controller On Data Load

I have a directive function scope.automaticallySelectClosingTime(). It takes the value of first selected dropdown value and creates a list of time on the second select drop-down. I

Solution 1:

try to add scope parameter to the directive, you can use this:

.directive('closingTimeSync', function() {
    return {
      template: `<md-select ng-model="ngModel" ng-disabled="time.uiStoreOpen === false" ng-model="openCloseSet[1]">
                        <md-option ng-repeat="uiTime in closingTimes" ng-value="uiTime.msValue">
                            {{::uiTime.display}}
                        </md-option>
                    </md-select>`,
      scope: {
            ngModel: '='
      },
      replace: true,
      transclude: true,
      link: function(scope) {
        scope.automaticallySelectClosingTime = function(msValue) {
          scope.closingTimes = scope.uiAvailableTimes;
          var dayMS = 86400000 - 1;
          var remainingTimings = [];
          var index = scope.closingTimes.map(function(obj) {
            return obj.msValue;
          }).indexOf(msValue);
          index = (index === scope.uiAvailableTimes.length - 1) ? 1 : index + 1;
          scope.closingTimes = scope.closingTimes.slice(index, scope.uiAvailableTimes.length);
          if (msValue !== dayMS) {
            remainingTimings = scope.uiAvailableTimes.slice(1, index - 1);
          }
          scope.closingTimes = scope.closingTimes.concat(remainingTimings);
        };
      }
    };
  })

and also you will need to add the ng-model inside the directive:

<closing-time-sync ng-model="paramFromController"></closing-time-sync>

hope that will resolve your issue.
