javascript - Ionic framework ionicView.entered event fired twice -


i'm playing ionicview events fired whenever views become active, , i'm using side menu template can re-use when creating project. seems if put listener $ionicview.entered event in appctrl (the 1 used side menu template, belongs abstract state in ui-router configuration) gets called twice in row of subviews (like, when using app.someotherview state).

i don't know if expected behavior because documentation expect fire once, no matter if change subview (the menucontent view).

i'd know if expected behavior , if so, how have event fired once every time gets show side menu template.

this i've got written:

this application module:

.config(function($stateprovider, $urlrouterprovider, $httpprovider) {   $stateprovider    .state('app', {     url: "/app",     abstract: true,     templateurl: "templates/menu.html",     controller: 'appctrl'   })    .state('app.overview', {     url: "/overview",     views: {       'menucontent': {         templateurl: "templates/overview.html",         controller: 'overviewctrl'       }     }   })    .state('login', {     url: "/login",     templateurl: "templates/identificationscreen.html",     controller: "identificationctrl"   })    .state('app.agenda', {     url: "/agenda",     views: {       'menucontent': {         templateurl: "templates/agenda.html",         controller: 'agendactrl'       }     }   });    $httpprovider.interceptors.push('credentialsinjector');    // if none of above states matched, use fallback   $urlrouterprovider.otherwise('/login');

then appctrl this:

angular.module('dashboard.controllers.app', []) .controller('appctrl', function($scope, $ionicmodal, $timeout, $ionicsidemenudelegate, authservice, $state) {     $scope.logout = function() {         authservice.logout();         $state.go('login');     };      $scope.$on('$ionicview.enter', function(){ //this fired twice in row         console.log("app view (menu) entered.");         console.log(arguments);      });      $scope.$on('$ionicview.leave', function(){ //this 1 when leaving, happens when logout         console.log("app view (menu) leaved.");         console.log(arguments);     }); });

the menu template:

<ion-side-menus enable-menu-with-back-views="false">   <ion-side-menu-content edge-drag-threshold="true">     <ion-nav-bar class="bar-stable">       <ion-nav-back-button>       </ion-nav-back-button>       <ion-nav-buttons side="left">         <button class="button button-icon button-clear ion-navicon" menu-toggle="left">         </button>       </ion-nav-buttons>     </ion-nav-bar>     <ion-nav-view name="menucontent"></ion-nav-view>   </ion-side-menu-content>    <ion-side-menu side="left">     <ion-header-bar class="bar-stable">       <h1 class="title">appoint!</h1>     </ion-header-bar>     <ion-content>       <ion-list>         <ion-item nav-clear menu-close href="#/app/overview">           overview         </ion-item>         <ion-item nav-clear menu-close href="#/app/agenda">           agenda         </ion-item>         <ion-item nav-clear menu-close ng-click="logout()">           logout         </ion-item>       </ion-list>     </ion-content>   </ion-side-menu> </ion-side-menus>

a simple workaround is:

$scope.$on('$ionicview.enter', function(ev) {     if(ev.targetscope !== $scope)         return;     // code should run once });

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
