我正试图找到一种方法将Twitter Card元数据放在我网站的/*** BookComponent ***/
@RouteConfig([
{path: "/books/:id", component: BookDetailComponent, as: "BookDetail"},
])
export class BookComponent {
}
/*** BookDetailComponent ***/
export class BookDetailComponent {
book:Book;
constructor(private bookService:BookService,
private routeParams:RouteParams) {
}
ngOnInit() {
let id = this.routeParams.get("id");
this.bookService.getBook(parseInt(id))
.subscribe(book => this.book = book.json());
}
}
标记内。目前无法访问它,所以是否可以将其添加到代码中的其他位置?
答案 0 :(得分:0)
这是无效的HTML,不推荐使用。为什么您无法访问<head>
?
