Problem with visible property

Hi everyone, 

in my project I put 4 buttons that I want to hide at the start of experience. 

So, once set up the 2 D canvas, I print all the widget property in console with: console.log($scope.app.view.Home.wdg); and all is working fine. 

 

To achieve my porpouse I wrote this function: 

 

$scope.initializeExperience = function() {
 $scope.app.view.Home.wdg['reset']['visible']= false; 
 $scope.app.view.Home.wdg['rewind']['visible'] = false;
 $scope.app.view.Home.wdg['play']['visible'] = false;
 $scope.app.view.Home.wdg['replay']['visible']= false;
}

$scope.initializeExperience();


console.log($scope.app.view.Home.wdg);

 

but, in the google chrome console appears: 

 

TypeError: Cannot set property 'visible' of undefined
 at b.$scope.initializeExperience (VM10710 app.js:229)

 at Object.x.appendViewElement (VM13 ionic.bundle.min.js:471)
 at Object.render (VM13 ionic.bundle.min.js:470)

 

Any idea?

Hi @leonardosella ,

I think the problem is caused that the widget is not initialized yet when you call the code.

Simple call the code inside one of the events  $ionic.afterEnter or modelLoad:

 

 

$scope.$on('$ionicView.afterEnter', function() {
$scope.initializeExperience();
})

 

further examples:

rootScope.$on('modelLoaded', function() { 
$scope.inializeExperience();
});
// or jquery
angular.element(document).ready(function () {$scope.inializeExperience();});
