Template parse error: Unexpected closing tag

Question

我在我的应用程序中重新加载某些路线时遇到错误。第一次加载工作正常 http://localhost:8001，所有其他路由从那里开始工作。但是，如果我在其他路线上重新加载页面，我会在下面收到异常...

例如：

http://localhost:8001 有效
http://localhost:8001/application 有效
http://localhost:8001/application/ 无效
http://localhost:8001/application/add 无效

有人知道为什么会这样吗？

异常：

EXCEPTION: Template parse errors:
Unexpected closing tag "head" ("
  <link rel="stylesheet" href="/static/styles/default.css">
  <!-- endinject -->
[ERROR ->]</head>

<body>
"): RootRoute@12:0
Unexpected closing tag "html" ("
</body>

[ERROR ->]</html>"): RootRoute@38:0

root.route.ts:

@Component(...)
@RouteConfig([
  { path: '/', name: 'Root', component: DashboardComponent, useAsDefault: true },
  { path: '/application/...', name: 'Application', component: ApplicationRoute},
  { path: '/:unknown', redirectTo: ['/Root'] }
])
export class RootRoute {...}

application.route.ts:

@Component({ template: `<p>Dummy Template...</p>` })
export class Dummy {}

@Component(...)
@RouteConfig([
  { path: '/', name: 'Root', component: Dummy },
  { path: '/add', name: 'Add', component: Dummy }
])
export class ApplicationRoute extends RouteComponent {...}

index.html:

<!DOCTYPE html>

  <meta charset="utf-8">

//]]></script>

  <!-- endinject -->
</body>

</html>

更新：

我做了一些调试，发现错误是由 TemplateNormalizer, more specifically by HtmlParser.parse() 方法产生的。当我从 <head> 中删除 <meta> 标签时，错误就消失了。但没有其他事情发生 - 应用程序没有显示 - 即使 SystemJS 在后台加载了所有模块，也只呈现了 <div class="app-loader">...

我还注意到我的一项服务返回了奇怪的结果，原来我使用了相对 URL。这导致我将 <base href="/"> 添加到 header 并解决了所有问题......我不确定为什么，但它从 bootstrap.ts 中接缝 provide(APP_BASE_HREF, { useValue: '/' }) 被忽略有些地方...

Answer 1

将您的 application.route.ts 更改为：

@Component({ template: `<p>Dummy Template...</p>` })
export class Dummy {}

@Component(...)
@RouteConfig([
  { path: '/', name: 'Root', component: Dummy, useAsDefault: true },
  { path: '/add', name: 'Add', component: Dummy }
])
export class ApplicationRoute extends RouteComponent {...}

Answer 2

另见

https://angular.io/docs/ts/latest/guide/router.html

Add the base element just after the <head> tag. If the app folder is the application root, as it is for our application, set the href value exactly as shown here.

<base href="/">

或者添加

import {provide} from 'angular2/core';
import {APP_BASE_HREF} from 'angular2/router';

bootstrap(AppComponent, [
  ROUTER_PROVIDERS, 
  provide(APP_BASE_HREF, {useValue : '/' });
]);

在你的 bootstrap.

Answer 3

我正在处理 angular 5 并收到此错误，因为我将参数传递给 click 函数，例如迭代变量，这是错误的

 <td><a (click)="showReports({{row.site_id}})">{{row.site_name}}</a> </td>

所以我用

解决了这个问题

 <td><a (click)="showReports(row.site_id)">{{row.site_name}}</a> </td>
