如何在Angular中使用内容投影(又名包含) [英] How to use content projection (aka transclusion) in Angular

问题描述

我对角度4还是陌生的.

I am new to angular 4.

我对有角的4个嵌入式组件有疑问.

I have a doubt in angular 4 embedded components.

示例:

<hero-list>
    <hero></hero>
    <hero></hero>
</hero-list>

我想知道如何基于将组件嵌入另一个组件中的这种结构来创建视图.

I wanted to know how to create a view based on this structure that is embedding component inside another component.

推荐答案

您应该在hero-list-组件中使用<ng-content></ng-content>.这样您就可以在上面实现您的愿望.

You should use <ng-content></ng-content> in your hero-list-component. So you can realize your wish above.

hero-list.component.html

<div class="hero-list">
  <h1>Hero list</h1>
  <ng-content></ng-content>
</div>

现在您可以包装您的hero-item-组件，它们将被打印在hero-list组件内部.

And now you can wrap your hero-item-components and they will be printed inside of hero-listcomponent.

app.component.html

<hero-list>
  <hero-item></hero-item>
  <hero-item></hero-item>
</hero-list>

这是工作示例: https://stackblitz.com/edit/angular-nvpmtc
