如何使用超赞字体在angular5视图中显示评论星标 [英] How to display review stars in angular5 view using font-awesome

问题描述

我在数据库中有评论星级值.物品的示例 2.5 . 我想使用font-awesome在模板中显示它.

I have the review stars value in the database. Example 2.5 for an item. I want to display this in the template using font-awesome.

<ul class="rating inline-ul">
    <li><i class="fa fa-star amber-text"></i></li>
    <li><i class="fa fa-star amber-text"></i></li>
    <li><i class="fa fa-star amber-text"></i></li>
   <li><i class="fa fa-star"></i></li>
   <li><i class="fa fa-star"></i></li>
</ul>

根据评论值显示星星的方式是什么?

What will be the way to display the stars in accordance with the review value?

我使用了* ngIf，但是用很多代码和如何表示半颗星似乎显得有些矫

I used *ngIf, but that seems like overkill with a lot code and possibly how to represent the half stars.

 <ul class="rating inline-ul" *ngIf="2.5">
        <li><i class="fa fa-star amber-text"></i></li>
        <li><i class="fa fa-star amber-text"></i></li>
        <li><i class="fa fa-star amber-half"></i></li>
        <li><i class="fa fa-star"></i></li>
        <li><i class="fa fa-star"></i></li>
  </ul>
