遍历字符串数组-angular2 [英] Loop through array of strings - angular2

问题描述

还很基本，但是我无法弄清楚如何在angular2的html模板中显示字符串数组.

Yet very basic thing, but I am unable to figure out how to display array of strings in html template in angular2.

.html

<ul>
       <li *ngFor="#number of numberOptions">
          {{number}}
       </li>
</ul>

.ts

this.numberOptions= ["I", "II", "III", "IV", "V", "VI", "VII", "VIII", "IX", "X"];

上述技巧对我不起作用，文本编辑器显示ngFor中#number的错误.新版本是否已弃用?还是我在这里做错了什么?

The above trick is not working for me, text editor shows error for #number in ngFor. Is this deprecated in new versions? or am I doing anything wrong here?

推荐答案

您必须使用let声明变量number.

   <li *ngFor="let number of numberOptions">
      {{number}}
   </li>
