angular ui modal after close event

I will assume that you are using the Modal dialogs from angular-ui. But before going into the details a bit of documentation around promises in AngularJS is needed. You need to know that every then function can accept 3 parameters as such :

then(successCallback, errorCallback, notifyCallback) 

• successCallback is executed when the promise is resolved.
• errorCallback is executed when the promise is rejected.
• notifyCallback is executed when notified.

In the case of angular-ui’s modal, clicking on the backdrop will result in a rejected promise. With this in mind, your code could be changed to :

dialog.result.then(function () {
  alert('Modal success at:' + new Date());
}, function () {
  alert('Modal dismissed at: ' + new Date());
});
