Angular 中的范围继承 $broadcast

Question

我正在尝试在 Angular 中设置范围广播。 Datetimepicker 应该在 parent 网格中定义，children 应该继承它。我这样试过：

      $scope.dtBODStopValue = new Date()
      $scope.dtBODStartValue = new Date(new Date(new Date().getTime() - 7 * MS_PER_DAY));

改变Date/Time并广播到其他网格

        $scope.dateTimePickerBODStart = {
        change: function () {
                $scope.$broadcast(dtBODStartValue,dtBODStopValue);
          $scope.OnGridRefresh();
        }
      };

$scope.dateTimePickerBODStop = {
        change: function () {
                $scope.$broadcast(dtBODStartValue,dtBODStopValue);
          $scope.OnGridRefresh();
        }
      };

HTML:

    <input kendo-date-time-picker="dateTimePickerBODStart" k-ng-model="dtBODStartValue" k-options="dateTimePickerBODStart"/>
    <input kendo-date-time-picker="dateTimePickerBODStop" k-ng-model="dtBODStopValue" k-options="dateTimePickerBODStop"/>

根据文档 $broadcast 是范围方法

$scope.$broadcast(name, args);

所以你的情况应该是

$scope.$broadcast('datepickerUpdate', dtBODStartValue, dtBODStopValue);

然后是 child 范围内的听众

$scope.$on('datapickerUpdate', function (event, dtBODStartValue, dtBODStopValue) {
  //do stuff on change
})
