如何关闭Angular对话框？

Question

我想在DeleteIndicatorConfirm函数中关闭的一个函数中有角度对话框。我怎么能这样做？

 $scope.indicatoritems = this.item3;
    var modalInstance = ngDialog.openConfirm({
           template: 'modaldeleteindicator',
           className: 'ngdialog-theme-default',
           scope: $scope,


       });
    }

$scope.DeleteIndicatorConfirm = function () {

};
