hiding back button in ionic, angularjs
I had exactly same problem today.
Simplest solution is to use $ionicNavBarDelegate:
.controller('AppCtrl', function($scope, $location, $ionicNavBarDelegate) { var path = $location.path(); if (path.indexOf('submit') != -1) $ionicNavBarDelegate.showBackButton(false); else $ionicNavBarDelegate.showBackButton(true);})You can also wrap hideBackButton value in object and your code will work:
.controller('AppCtrl', function($scope, $location) { var path = $location.path(); $scope.options = $scope.options || {}; if (path.indexOf('submit') != -1) $scope.options.hideBackButton = true; else $scope.options.hideBackButton = false;})It works because in JS (as in many other languages) booleans are passed by value and object are passed by the referance and it affects how default Angular watchers are created. The downside of this method is that hidding of the button is not as smooth as in other ionic solutions.
Just in case, this is how your html should look like:
1st solution:
<body ng-app="starter" ng-controller="AppCtrl"> <ion-nav-bar class="bar-stable"> <ion-nav-back-button> </ion-nav-back-button> </ion-nav-bar></body>2nd solution:
<body ng-app="starter" ng-controller="AppCtrl"> <ion-nav-bar class="bar-stable"> <ion-nav-back-button hide-back-button="{{options.hideBackButton}}"> </ion-nav-back-button> </ion-nav-bar></body>
