[英]Angular2: template work, but templateUrl not
我想將html內容放在文件中,以便更容易理解。 我有這個:
import { Component, OnInit } from '@angular/core';
import { CommentService } from '../services/Comment';
import { Comment } from '../class/Comment';
@Component({
template: '<ul class="comments"><li *ngFor="let comment of Comments_array"><h3>{{comment.text}}</h3><span>{{comment.author}}</span></li></ul>',
providers: [CommentService]
})
export class CommentsComponent implements OnInit {
Comments_array: Comment[];
constructor(private commentService: CommentService) { }
ngOnInit() {
this.commentService.get_all_comments().subscribe(
(data) => {
this.Comments_array = data;
console.log ( this.Comments_array );
},
(error) => {
console.error(<any>error);
});
}
}
在這一刻,效果很好,但如果我在templateUrl中更改模板:'template / comments'
和模板/評論有:
<ul class="comments"><li *ngFor="let comment of Comments_array"><h3>{{comment.text}}</h3><span>{{comment.author}}</span></li></ul
// 一樣..
我收到這些錯誤:

我應該改用UTF-8或其他東西?
錯誤stacktrace清楚地說它的模板解析錯誤,你錯過了關閉ul
標簽。
你必須關閉ul
元素,因為Angular 2檢查嚴格的HTML解析,同時在html
文件中有模板。
模板/ comments.html
<ul class="comments">
<li *ngFor="let comment of Comments_array">
<h3>{{comment.text}}</h3>
<span>{{comment.author}}</span>
</li>
</ul>
