如何将窗口注入 Angular 2.1.0 [英] How to Inject Window into Angular 2.1.0

问题描述

在 Angular 2 的早期 RC 版本中，我能够通过添加

In the earlier RC releases of Angular 2 I was able to inject the window object by adding

{provide: Window, useValue: window}

到提供者数组.

自从升级到 angular 2 (2.1.0) 的最新稳定版本后，现在会引发控制台错误

Since upgrading to the latest stable release of angular 2 (2.1.0) this now throws a console error

compiler.umd.js:14268Uncaught 错误:无法解析 LoginComponent 的所有参数:(AuthService, UserMessagesService, ?).

compiler.umd.js:14268Uncaught Error: Can't resolve all parameters for LoginComponent: (AuthService, UserMessagesService, ?).

?在参数列表中是我试图注入 Window 对象的地方.

The ? in the parameter list is where I am trying to inject the Window object.

推荐答案

尝试:

@NgModule({
  declarations: [...],
  imports: [...],
  providers: [
   { provide: "windowObject", useValue: window}
  ]
})

export class HomeModule {}

在您的组件中:

constructor(@Inject("windowObject") window: Window})
