Angular2 addArticle 不是一个函数

Question

单击提交按钮时，我在控制台中遇到了这个消息，如果有人可以帮助我如何将时刻从node_modules导入到angula2项目！！

我的应用程序组件.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>

My app.module.ts

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

你已经在 app.module.ts 中编写了 addArticle 方法，你应该把它放在 app.component.ts 中

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

将 addArticle 方法移动到 app.component.ts，就像你在 app.component 中使用它一样.html

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; 
      } 
}

目前使用以下导入

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

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