如何在 angular2（打字稿）上使用带有 jquery 的 js 库？

Question

我尝试使用 typescript 将 angular js 迁移到 angularjs2。

我不明白如何使用 js 库。我有 main app.component ，我想在其中初始化一些库，例如简单的行：

$('#home').height($(window).height());

并通过attribute data-spy="scroll" data-target="#header-navbar" data-offset="51"

初始化

Index.html

<body data-spy="scroll" data-target="#header-navbar" data-offset="51" class="pace-done">

    <pm-app>Loading App...</pm-app>

                }
            }
        });
        System.import('app/main')
            .then(null, console.error.bind(console));
    </script>

</body>

一般main.ts

import { bootstrap }    from 'angular2/platform/browser';

// Our main component
import { AppComponent } from './app.component';

bootstrap(AppComponent);

空 app.component.

为了使用 jQuery，您首先必须在 index.html 中导入，比你可以在组件

的构造函数中初始化你的代码

constructor(){
   .....
   $('#home').height($(window).height());
}

万一 IDE 显示错误，您可以像这样在 class 顶部声明任何类型的 $ :-

...some  code here 
declare var $ : any;

export class App{
..///code goes here
}
