Angular Object.key-检索，仅从对象中获取一个属性 [英] Angular Object.key - Retrieve,get only one property from object

问题描述

我怎么只能从对象中检索一个属性?

How can i retrieve only one property from object?

在此示例中，我的对象具有2个属性:name和id

in this example i have object with 2 properties: name and id

   <div *ngFor="let post of objectKeys(_postArrayMatch.team1)">
      Team1: {{ _postArrayMatch.team1[post]}}
    </div>

我要排除ID，如何只显示name属性?

I want to exclude the id, how can i show only the name property?

我试图做这样的事情，但是那样行不通

I tried to do something like this, but it doesn't work that way

   <div *ngFor="let post of objectKeys(_postArrayMatch.team1)">
    Team1: {{ _postArrayMatch.team1[post].name}} 
 </div>

作为回应，我只是空了

推荐答案

如果只想显示一个元素，请不要使用*ngFor. ngFor用于在一个可迭代对象中循环多个元素.

If you want to show only one element, don't use *ngFor. ngFor is for looping over multiple elements in an iterable.

<div>
  Team1: {{ _postArrayMatch.team1.name}}
</div>
