javascript - 使用 ng-idle 时访问范围变量

Question

ng-idle 是一个自定义 Angular Directive(指令)，可以在 here 中找到这允许您的 Angular 应用程序检查用户是否空闲。

以前使用过该指令的人是否知道在编辑该指令的属性时 $scope 是否存在问题？

这是我的 JS:

// include the `ngIdle` module
var app = angular.module('demo', ['ngIdle', 'ui.bootstrap']);

app
.controller('EventsCtrl', function($scope, Idle, $modal) {
    $scope.logIn = function(){
        $scope.loggedIn = true;
        Idle.watch();
    };

    $scope.logOut = function(){
        $scope.loggedIn = false;
        Idle.unwatch();
    };

    $scope.events = [];

    $scope.$on('IdleStart', function() {
        $scope.amIdle = true;
    });

    $scope.$on('IdleWarn', function(e, countdown) {
        // follows after the IdleStart event, but includes a countdown until the user is considered timed out
        // the countdown arg is the number of seconds remaining until then.
        // you can change the title or display a warning dialog from here.
        // you can let them resume their session by calling Idle.watch()
    });

    $scope.$on('IdleTimeout', function() {
        // the user has timed out (meaning idleDuration + timeout has passed without any activity)
        // this is where you'd log them
        $scope.loggedIn = false;
        $scope.amIdle = false;
        Idle.unwatch();
        console.log("Timeout has been reached");
        console.log($scope.loggedIn);
    });

    $scope.$on('IdleEnd', function() {
        // the user has come back from AFK and is doing stuff. if you are warning them, you can use this to hide the dialog
        $scope.amIdle = false;
    });

   /*$scope.$on('Keepalive', function() {
        $scope.amIdle = false;
    });*/

})
.config(function(IdleProvider, KeepaliveProvider) {
    // configure Idle settings
    IdleProvider.idle(5); // in seconds
    IdleProvider.timeout(5); // in seconds
    KeepaliveProvider.interval(1); // in seconds
})

登录/注销的东西只是控制loggedIn变量的基本东西，它只是与ng-show一起使用来拥有一个非常基本的登录屏幕来测试ng-idle的超时功能。空闲/检测用户是否回来也很好，唯一的问题是 $scope.$on('IdleTimeout') 函数。

程序到达控制台日志，并显示两个登录都是错误的，并且超时已开始，但应用程序没有相应更新。当注销为 false 时，用户应返回到登录屏幕，该屏幕在用户单击注销按钮时起作用，但在超时的情况下不起作用。

问题似乎是，无论出于何种原因，应用程序在变量更改后都没有更新。通过添加修复了此问题

$scope.$apply();

在 IdleTimeout 函数中将两个 bool 值设置为 false 后。
