angularjs - Angular JS & Phonegap back button event -


i have mainctrl containing backstack history, this;

$scope.urlhistory = [];  $scope.$on('$routechangesuccess', function () {     if ($location.$$absurl.split('#')[1] !== $scope.urlhistory[$scope.urlhistory.length - 1]) {         $scope.urlhistory.push($location.$$absurl.split('#')[1]);     } });

then, in same controller i've got goback() function i'd call when button pressed;

$scope.goback = function () {     $scope.urlhistory.pop();     $location.path($scope.urlhistory[$scope.urlhistory.length - 1]); };

this supposed work because index.html call ng-click="goback()" , works expected.

i use device events, same controller;

function onbackkeydown() {   alert("back");   $scope.goback(); }  document.addeventlistener("deviceready", ondeviceready, false); // device apis available // function ondeviceready() {   // register event listener   alert("deviceready");   document.addeventlistener("backbutton", onbackkeydown, false); };

i can see alerts, app's not navigating back. happens though, because if press device button twice, ng-click="goback()" takes me start page of app. using $scope wrong? experiencing on win phone & android. using phonegap build.

edit: i'm after here why $scope.goback(); function work differently when called devicelistener.

this solved it:

  $scope.goback = function () {     if (urlhistory == '/') {        document.removeeventlistener("backbutton", onbackkey, false);      };         urlhistory.pop();     $location.path(urlhistory[urlhistory.length - 1]);     $scope.$apply();   };

the scope.$apply(); answer. it's necessary when executing angular expressions outside of angular. (angularjs $location not changing path)
