AngularJS-观看模态窗口从另一个控制器关闭

Question

I have main controller with

$scope.showDialog = function(ev) {
    $mdDialog.show({
      controller: 'DialogController',
      templateUrl: 'partials/dialog.tmpl.ejs',
      targetEvent: ev
    })
};

and dialog contoller with

$scope.hide = function() {
    $mdDialog.hide();
};

(The dialog directive I'm using is from angular material). How can I watch when dialog window is closed from main controller?

Answer 1

Use the promise returned from the mdDialog :

 $mdDialog.show({
      controller: 'DialogController',
      templateUrl: 'partials/dialog.tmpl.ejs',
      targetEvent: ev
 }).then(function(data) {
      // dialog was hidden with $mdDialog.hide()
 }, function() {
      // dialog was canceled with $mdDialog.cancel()
 })
