The Angular UI Datepicker is not reflecting changes in scope variables within the dates-disabled function

I'm currently working with AngularJS and the Angular UI Bootstrap.

I've encountered an issue that I initially thought was related to scope, then initialization, but now I'm stuck trying to figure out what's causing the problem. I've included a link to a Plunker in hopes that someone can help me troubleshoot.

Here's the scenario: A user selects a donut they want to purchase. If the donut isn't available daily, a modal pops up prompting them to choose a date for their order. The problem lies in the fact that the datepicker doesn't seem to recognize the value of $scope.theActiveDonut. It defaults back to the Cream Donut upon initialization, even though my console log and angular.element($0).scope() show that $scope.theActiveDonut has been updated. This discrepancy is visible in the console.log().

Link to my Plunker: http://plnkr.co/edit/rziyPLvsiiZB346qmSC5?p=preview

Even though the console.log() confirms that $scope.theActiveDonut has changed, within $scope.thingy, it always reverts back to the Cream Donut value.

Answer №1

To manage your $modal effectively, it is recommended to create a separate controller for it and pass data to that controller using:

resolve: {
            theActiveDonut: function() { return $scope.theActiveDonut }
          }

When initializing the modal, ensure that once the date is selected and the user clicks 'Okay,' you use 

modalInstanceII.close('making-a-new-one');
. In case of cancellation, utilize 
modalInstanceII.dismiss('canceled');

You can find an example on Plunkr here: http://plnkr.co/edit/mUIfZOEqj3r0zNw5rQDB?p=preview

Answer №2

When it comes to modal instances, one thing to note is that they do not inherit the scope of the parent controller. Instead, they come with their own separate scope.

If you need to pass a variable from the calling controller to the modal instance, you can achieve this by utilizing a resolve block:

modalInstance = $modal.open({
          animation: true,
          templateUrl: 'myModalContent.html',
          controller: 'ModalController',
          scope: $scope,
          size: "sm",
          resolve: {
            selectedValue: function() { return $scope.selectedValue; }
          }
        });
