AngularJS view fails to reflect updates in the model

This issue with Angular has been widely discussed online, but I ask for your patience. I have tried various solutions without success. Here is a simplified version of my code:

View:

<div ng-hide="{{beHidden}}"></div>

Controller:

// Set beHidden to initially be false (Works when set to true as well)

$scope.beHidden = false;

// A popup prompts the user to choose whether to hide the div

    var confirmPopup = $ionicPopup.confirm({
        title: 'Hidden Div',
        template: 'Do you want to hide the div?',
        cancelText: 'No',
        okText: 'Yes'
    }).then(function(res) {

      if(res) {          
        // User chose to hide div
        $timeout(function() {
          $scope.beHidden = true;
        });
      } else {          
        // User chose NOT to hide div
        $timeout(function() {
          $scope.beHidden = false;
        });
      }

    });

However, this approach does not work. I have tried using $scope.$apply, but encountered an error stating "digest already in progress". I have also used $timeout without errors, but the view still doesn't update to hide the div when the user chooses to do so. Any suggestions?

And yes, I am correctly injecting $timeout into the controller...

Answer №1

Substitute:

<div ng-hide="{{beHidden}}"></div>

Replace it with:

<div ng-hide="beHidden"></div>

In addition, there is no requirement to enclose the modification of beHidden within a $timeout function call.

Answer №2

I encountered a similar issue (with the same exact scenario) and found that it was triggered by the {{ }} parentheses. It's advisable to avoid using these brackets in the view.

Answer №3

It seems like the issue here could be related to scope.

Do you think the scope might be different in your situation?

One possible solution is to test it out.

Here's a suggestion:

<div ng-hide="{{$root.beHidden}}"></div>

In the Controller:

.run(function($rootScope) {
    $rootScope.beHidden = false;
})

.controller('yourCtrl', function($scope, $rootScope) {
  // implement condition here
  $rootScope.beHidden = true;
  $timeout(function(){
    $rootScope.apply()
  }, 100);
})
