Angular2 addArticle不是函數

Question

當單擊“提交”按鈕時，我在控制台中遇到此消息，並且是否有人可以幫助我如何將時刻從node_modules導入angula2項目！

我的app.component.html

<form class="ui large form segment">
  <h3 class="ui header">Add a Link</h3>
  <div class="field">
    <label for="title">Title:</label>
    <input name="title" #newtitle>
  </div>
  <div class="field">
    <label for="link">Link:</label>
    <input name="link" #newlink>
  </div>
  <div>
    <button (click) ="addArticle(newtitle, newlink)" class="ui positive button">Submit link</button>
  </div>

</form>

我的app.module.ts

export class AppModule { 
  addArticle(title: HTMLInputElement, link:HTMLInputElement): boolean{ 
    console.log('title: ${title.value} and link: ${link.value}'); 
    return false; 
  } 
 }

您已在app.module.ts中編寫了addArticle方法，應將其放在app.component.ts中

export class AppModule { 
  addArticle(title: HTMLInputElement, link:HTMLInputElement): boolean{ 
    console.log('title: ${title.value} and link: ${link.value}'); 
    return false; 
  } 
 } 

在app.component.html中使用addArticle方法時將其移動到app.component.ts

export class AppComponent {
  title = 'Okay, proceed .!';
  names = [];
 // myDate = Date;

  constructor(){
    this.names = ['Tuan','Mark','Kevin'];
  //  this.myDate = new Date();
  }
 addArticle(title: HTMLInputElement, link:HTMLInputElement): boolean{ 
        console.log('title: ${title.value} and link: ${link.value}'); 
        return false; 
      } 
}

暫時使用以下導入

import {MomentModule} from 'angular2-moment/module';

在npm install angular2-moment之后npm install angular2-moment .. http://ngmodules.org/modules/angular2-moment
