AngularJS强制后退按钮路线

时间：2016-09-17 16:14:58

标签： javascript angularjs ionic-framework

我的后退按钮将我发送到我的应用程序的第一页/状态（cadastreSe）。如何强制它返回上一页/状态（'menu.temporada2016'），我的按钮id =“temporada2016-button3”处于活动状态。 angularjs有可能吗？

我想用$ scope启用它。$ on（'$ ionicView.beforeEnter'...

状态：

angular.module('app.routes', [])

.config(function($stateProvider, $urlRouterProvider) {

$stateProvider


.state('menu.temporada2016', {
cache: false,
url: '/page1',
views: {
  'side-menu21': {
    templateUrl: 'templates/temporada2016.html',
    controller: 'temporada2016Ctrl',
    params: { dataToTemp: false }        
  }
}
})

.state('menu.fotos', {
url: '/page2',
views: {
  'side-menu21': {
    templateUrl: 'templates/fotos.html',
    controller: 'fotosCtrl'
  }
}
})

.state('menu.configuraEs', {
url: '/page3',
views: {
  'side-menu21': {
    templateUrl: 'templates/configuraEs.html',
    controller: 'configuraEsCtrl'
  }
}
})

.state('menu', {
url: '/side-menu21',
templateUrl: 'templates/menu.html',
abstract:true
})

.state('detalhes', {
cache: false,
url: '/page4',
params: {
  dataToDetails: false
},
templateUrl: 'templates/detalhes.html',
controller: 'detalhesCtrl'
})

.state('cadastreSe', {
url: '/page5',
templateUrl: 'templates/cadastreSe.html',
controller: 'cadastreSeCtrl'
})

.state('home', {
url: '/page6',
templateUrl: 'templates/home.html',
controller: 'homeCtrl'
})

.state('suporte', {
url: '/page7',
templateUrl: 'templates/suporte.html',
controller: 'suporteCtrl'
})

.state('fotos2', {
url: '/page8',
templateUrl: 'templates/fotos2.html',
controller: 'fotos2Ctrl',
params: {
  dataToFotos: false
}
})

$urlRouterProvider.otherwise('/page5')



});

控制器：

.controller('fotos2Ctrl', ['$scope', '$state', '$ionicModal', '$ionicSlideBoxDelegate', '$ionicScrollDelegate', function ($scope, $state, $ionicModal, $ionicSlideBoxDelegate, $ionicScrollDelegate) {

$scope.$on('$ionicView.beforeEnter', function(event, viewData){
    viewData.enableBack = true;
});

$scope.$on('$routeChangeSuccess', function(event, current, previous){


});

if(!$state.params.dataToFotos) {
    console.log($state.params.dataToFotos);

}else{

    console.log($state.params.dataToFotos);
    $scope.images = $state.params.dataToFotos.album;         
}

$scope.zoomMin = 1;

// image gallery
$scope.showImages = function(index) {
    $scope.activeSlide = index;
    $scope.showModal('templates/popover.html');
}

$scope.showModal = function(templateUrl) {
    $ionicModal.fromTemplateUrl(templateUrl, {
        scope: $scope,
        animation: 'slide-in-up'
    }).then(function(modal) {
        $scope.modal = modal;
        $scope.modal.show();
    });
}

// Close the modal
$scope.closeModal = function() {
    $scope.modal.hide();
    $scope.modal.remove()
};

$scope.updateSlideStatus = function(slide) {

    var zoomFactor = $ionicScrollDelegate.$getByHandle('scrollHandle' + slide).getScrollPosition().zoom;

    if (zoomFactor == $scope.zoomMin) {
        $ionicSlideBoxDelegate.enableSlide(true);
    } else {
        $ionicSlideBoxDelegate.enableSlide(false);
    }
};

}])

您可以通过向特定视图的模板添加新页面来覆盖特定页面的标题。它应该在标签之外和之上。只需让它镜像你的正常标题。然后实现一个看起来完全相同的后退按钮，但是它会触发一个ng-click事件，然后您可以使用$ state.go将用户路由到您希望他返回的特定视图。 ）或使用$ ionicHistory依赖性导航回导航堆栈。
