[Solved] Detect if ion-nav-button is shown

[adrisimoMM]

I’m trying to do this but $rootScope.$viewHistory gets ‘undefined’.
That embarassing. But other people signed this.

Howdy,

After upgrade to Ionic beta 14 I found that $rootScope.$viewHistory is undefined. I didn’t see any information in DOCs.

Please help

By the way, the working method to check the state of back button is this:

@Damiant

I found the above code to not work in beta 14 and had to do the following instead (hope this helps out anyone else searching for an answer):

$rootScope.$on('$ionicView.beforeEnter', function (e, data) {        
        if (data.enableBack) {
           doSomething();
          }
     });

I did so:

$rootScope.$on('$ionicView.beforeEnter',function(e,data){
     $rootScope.isBackButtonShown = data.enableBack
)}

in the view:

 <button ng-if="!isBackButtonShown" ng-click="myGoBack()"></button>

that was to hide my custom back button if there is already yhe IONIC one
