处置Angular 2应用或组件 [英] Dispose Angular 2 App or Component

问题描述

反正有处置angular2应用程序或组件的方法吗?我正在混合使用ASP.NET MVC和Angular 2应用程序，其中ASP.NET MVC加载了包括Angular 2 App在内的部分视图.现在，我需要为每个局部视图提供一个关闭按钮，以将自身从DOM中删除，并在视图内部放置加载的Angle 2，以避免内存泄漏.无论如何，有没有要杀死Angular 2应用程序?

Is there anyway to dispose angular2 app or component? I'm doing a mixed ASP.NET MVC and Angular 2 app which ASP.NET MVC loads partial views including Angular 2 App. Now I need a close button for each partial view to remove itself from the DOM and dispose loaded angular 2 inside the view to avoid memory leak. Is there anyway to kill angular 2 app ?

推荐答案

更新

.dispose()是destroy() (自beta.16起)

原始

自举组件时，将获得根组件(AppComponent)的ComponentRef.要对其进行处置，请调用其dispose()方法:

When you bootstrap a component, you get a ComponentRef of the root component (AppComponent). To dispose it call its dispose() method:

bootstrap(AppComponent, [ROUTER_PROVIDERS,
    provide(LocationStrategy, {useClass: HashLocationStrategy}])
    .then((ref) => {
      setTimeout(()=> {
        ref.dispose();
      }, 3000);
    });
  .catch(err => console.error(err));

(您可以在某个位置分配ref变量以供以后重用.这只是为了演示可以处理Angular应用程序.)

(You can assign the ref variable somewhere for later reuse. This is just to demonstrate that an Angular application can be disposed.)
