angularjs – 我如何正确使用typescript构造函数之外的angular $

interface INavigationController {
        username: string;
        password: string;
        loggedIn: boolean;
        ready: boolean;
        signIn(): void;
        signOut(): void;
    }

    class NavigationController implements INavigationController {
        username: string;
        password: string;
        loggedIn: boolean;
        ready: boolean;

        static $inject = ['$timeout'];
        constructor(private $timeout: ng.ITimeoutService) {
            var vm = this;
            vm.username = this.username;
            vm.password = this.password;
            vm.ready = true;

            // The line below work just fine from within here - but i want the behavior
            // when someone clicks a button,not directly like this.
            // Remove vm.ready = true above,before...
            //$timeout(function () { vm.ready = true;},2200);}

        signIn() {
            if (!this.username || !this.password) {
                alert("You need to frickin enter som details,man!");
            } else {
                this.ready = false;
                this.$timeout(function () {
                    this.ready = true;
                },2200);
            }
        }

我还尝试将invokeApply？：boolean设置为true：

this.$timeout(function () {
    this.ready = true;
},2200,true);

– 没有任何成功……

如果我是console.log(this.ready);从这个.$timeout(function()…它会在2200ms后显示为true,但似乎$apply()不适用？

如果有人可以启发我如何正确使用$timeout和其他类似的服务,我将不胜感激 – 最好使用样式指南我的目标是使用“controllerAs with vm” – John Papa
