如何在 Angular 2 项目中提供路由器导航功能 [英] How to provide a router navigate function in Angular 2 project
问题描述
在我的 Angular 2 项目中,我有一个自定义函数 goToObject(objectType:string, objectID: number)
,我用它在我的应用程序中的几个不同组件中导航到不同的对象.该函数如下所示:
In my Angular 2 project I have a custom function goToObject(objectType:string, objectID: number)
that I use to navigate to different objects throughout a couple of different components in my application. The function looks as follows:
goToObject(objectType:string, objectID: number) {
this._router.navigate([type, id]);
}
我想知道是否有一种方法可以在我的整个项目中提供此功能,而无需在每个组件中单独定义它.我猜更难的是这个函数需要使用一个路由器对象的实例.我是否必须尝试在我的基础组件中提供它?
I was wondering if there is a way to provide this function throughout my complete project, without having to define it in each component separately. What makes it harder I guess is that this function needs to use a instance of a router object. Would I have to try to provide it in my base component?
推荐答案
您可以使用共享服务
@Injectable()
export class RouteServices {
constructor(private _router:Router) {}
navigate(...) {
this._router.navigate([type, id]);
}
}
然后在根组件中提供它并注入到你想使用它的地方并调用它的方法.
then provide it at the root component and inject it where you want to use it and call its methods.
