Question

我使用angular 4以及Webpack和Yarn作为包管理器。使用JIT开始我的项目并尝试使用ngtools / webpack转移到AOT。在尝试使用以下方法构建项目时：

yarn build

我收到错误：

ERROR in window is not defined

我已从项目中删除了所有窗口引用，以确保在我的项目中不会发生错误。我的结论是它发生在我正在加载的外部模块中。虽然因为错误信息似乎被打破了，但无法分辨出来。试图以各种不同的方式包括它，主要是这些问题： Expose jQuery to real Window object with Webpack，https://stackoverflow.com/a/28989476/2823310但目前对我没有任何作用。

我认为这段代码：

var globalWindow = {};
globalWindow.$ = globalWindow.jQuery = require("jquery");

new webpack.DefinePlugin({
      window: globalWindow
    })

是解决问题的方法，但它产生了更多相同的问题：

ERROR in document is not defined

如何在实际存在之前对窗口对象进行全局引用（AOT - 提前不应该真正知道真正的窗口对象）。有角度4和webpack的AOT可能还不够成熟吗？因为网上没有太多关于它的信息。

似乎与此主题有关： window is not defined using Angular4 + AoT + Webpack2 但没有回答。

Answer 1

在角度应用程序中，您需要注入窗口，因为在组件内部无法理解。你可以通过@Inject(WINDOW) private window: any

在构造函数中注入它

整个构造函数

@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.scss']
})
export class AppComponent implements OnInit {
  constructor(
    private router: Router,
    @Inject(WINDOW) private window: any
  ) {

  }

}

Answer 2

您只需在组件上方输入

即可

declare var window: any;

您没有输入支持，但您可以将窗口对象用作普通窗口。

使用AOT编译webpack 3时定义窗口
