如何清除离子中的本地存储数据？

Question

这是我的代码.

$scope.logout=function(){
    localstorage.set('user_id', "");
    localstorage.set('access-token', "");
    localstorage.set('isUserTraverseColony', 0);
    localstorage.set('isStarted', 0);
    $window.localStorage.clear();
    $window.localStorage.removeItem(access-token);
    $ionicHistory.clearCache();
    $ionicHistory.clearHistory();
 };

我想从我的localStorage中删除access-token变量,当我使用它时它适用于浏览器

 $window.localStorage.clear();
 $window.localStorage.removeItem(access-token);

但它不适用于我的应用程序.

这是我的本地存储工厂

angular.module('starter.controllers').factory('localstorage', ['$window', '$localStorage','$q', function ($window, $localStorage,$q) {
    return {
        set: function (key, value) {
             var deferred = $q.defer();
            $window.localStorage[key] = value;
                 deferred.resolve(1);
                 return deferred.promise;
        },
        get: function (key, defaultValue) {
            return $window.localStorage[key] || defaultValue;
        },
        setObject: function (key, value) {
            $window.localStorage[key] = JSON.stringify(value);
        },
        getObject: function (key) {
            return JSON.parse($window.localStorage[key] || '{}');
        }
    }

}]);

任何的想法？

我平均也遇到过同样的问题.我正在使用一些全局变量用于本地存储.你的代码似乎没问题.但你可以更好地优化它

$scope.logout = function(){
  $window.localStorage.clear();
    $ionicHistory.clearCache();
    $ionicHistory.clearHistory();
 };

你不需要设置

localstorage.set('user_id', "");
localstorage.set('access-token', "");
localstorage.set('isUserTraverseColony', 0);
localstorage.set('isStarted', 0);

因为你正在清除它们.
