Angular2异常:无法绑定到’ngFor’,因为它不是已知的本机属性

前端之家收集整理的这篇文章主要介绍了Angular2异常:无法绑定到’ngFor’,因为它不是已知的本机属性前端之家小编觉得挺不错的,现在分享给大家,也给大家做个参考。
我究竟做错了什么?
import {bootstrap,Component} from 'angular2/angular2'

@Component({
  selector: 'conf-talks',template: `<div *ngFor="talk of talks">
     {{talk.title}} by {{talk.speaker}}
     <p>{{talk.description}}
   </div>`
})
class ConfTalks {
  talks = [ {title: 't1',speaker: 'Brian',description: 'talk 1'},{title: 't2',speaker: 'Julie',description: 'talk 2'}];
}
@Component({
  selector: 'my-app',directives: [ConfTalks],template: '<conf-talks></conf-talks>'
})
class App {}
bootstrap(App,[])

错误

EXCEPTION: Template parse errors:
Can't bind to 'ngFor' since it isn't a known native property
("<div [ERROR ->]*ngFor="talk of talks">
我错过了在谈话前:
<div *ngFor="let talk of talks">

注意,as of beta.17使用#…来声明局部变量在结构化指令(如NgFor)中已被弃用。请改用let。
< div * ngFor =“#talk of talks”>现在变成< div * ngFor =“让谈话”>

原始答案:

我错过了#在面前说话:

<div *ngFor="#talk of talks">

这是很容易忘记#。我希望Angular异常错误消息,而是说:你再次忘记了#。
