如何在嵌套的 *ngFor angular 中将父键传递给子键

问题描述

我需要将父循环的键传递给另一个数组。但它不起作用。下面是我的代码

MirrorMakerMessageHandler

contact_settings_title 是另一个数组

<div  *ngFor="let con_settings of contact_settings | keyvalue">
 <h5 class="mt-0 task-header header-title">{{contact_settings_title.key}}</h5>
</div>

解决方法

<div  *ngFor="let con_settings of contact_settings | keyvalue">
 <h5 class="mt-0 task-header header-title">{{ contact_settings_title[key] }}</h5>
</div>
