如何使@HostListener 在 IE 11 中工作？

Question

我正在构建一个 Angular 应用程序。我正在使用 @HostListener，它在 firefox、safari 和 chrome 中运行良好，但是当我在 Internet Explorer 11 上运行它时，它不起作用。有没有办法使这项工作？代码如下所示。

@HostListener('window:scroll', ['$event']) onScrollEvent($event){
    console.log("hi");

}

上述内容在 safari、chrome 和 firefox 上滚动时将 hi 打印到控制台，但在 IE11 上不起作用。如何在 IE11 上进行这项工作？

我的 package.json 看起来像这样

})
