我试图将一个Angular 2应用程序加载到Chrome的弹出窗口中。
在使用Angular 1.5之前，我已经完成了这个工作，但尝试使用Angular 2并发生错误。

我有把< base href =/> 标签放到我的popu.html中。但问题是vendor.js和main.js被Chrome加载（在被popup.html加载之前），所以没有HTML页面可以放置< base href = />>
只是想知道我可以如何解决这个问题。
Popup.html
<！doctype html>
< html>
< head>
< base href =/>
< meta charset =utf-8>
< title> FountainJS< / title>
< meta name =descriptioncontent =>
< meta name =viewportcontent =width = device-width>
< link href =../ styles / popup.css =stylesheet>
< / head>
< body>
< div style =width：200px; height：150px;>
< fountain-root> My Awesome Chrome Popup应该加载Angular 2 right< / fountain-root>
< script type =text / javascriptsrc =../ scripts / vendor.js>< / script>
< script type =text / javascriptsrc =../ scripts / main.js>< / script>
< / div>
< / body>
< / html>
您可以在代码中设置基本href， p>
从'@ angular / common'导入{APP_BASE_HREF};
$ b $ @NgModule（{
providers：[
{provide：APP_BASE_HREF，useValue：'/'}
]
}）
class AppModule {}
I am building a Chrome Browser Action Extension.
I am attempting to load an Angular 2 application into the Popup Window in Chrome.
I have done this before using Angular 1.5, but attempting with Angular 2 and getting an error.
Unhandled Promise rejection: No base href set. Please provide a value for the APP_BASE_HREF token or add a base element to the document. ; Zone: ; Task: Promise.then ; Value: Error: No base href set. Please provide a value for the APP_BASE_HREF token or add a base element to the document.(…) Error: No base href set. Please provide a value for the APP_BASE_HREF token or add a base element to the document.
I have put the <base href="/"> tag into my popu.html. But the problem is that vendor.js and main.js get loaded underneath by Chrome (and before being loaded by popup.html) and so there is no HTML page in which to put <base href="/">
Just wondering how I can resolve this issue.
Popup.html
<!doctype html>
<html>
<head>
<base href="/">
<meta charset="utf-8">
<title>FountainJS</title>
<meta name="description" content="">
<meta name="viewport" content="width=device-width">
<link rel="icon" type="image/png" href="http://fountainjs.io/assets/imgs/fountain.png"/>
<link href="../styles/popup.css" rel="stylesheet">
</head>
<body>
<div style="width: 200px; height: 150px;">
<fountain-root>My Awesome Chrome Popup should load with Angular 2 right Here</fountain-root>
<script type="text/javascript" src="../scripts/vendor.js"></script>
<script type="text/javascript" src="../scripts/main.js"></script>
</div>
</body>
</html>
You could set the base href in code instead
import { APP_BASE_HREF } from '@angular/common';
@NgModule({
providers: [
{ provide: APP_BASE_HREF, useValue: '/' }
]
})
class AppModule {}
