我有2个独立的组件内的应用程序组件。第一个是工具栏,另一个是sidenav组件。我想要实现的功能和我已经完成的功能(使用reactive x pattern)是当从工具栏中单击按钮时,sidenav在2个状态(从64px到240px宽度,反之亦然)之间切换。2个独立组件之间的通信angularJS 2
我已经在共享服务中使用了一个通用行为主题,以便在单击工具栏按钮时发出数据,并使用sidenav组件内的订阅者来侦听发出的数据。
我的问题是如果有一种方法可以使用另一种方法(如官方文档中所述的@Input或@Output)完成相同的结果,或者反应灵敏的x模式馈送完全满足我的需求?

有没有这样的事情angularJS 2. Angular和AngularJS是不同的框架,A2的问题不应该有angularjs标签。 – estus
