角度7.1.4 HTML避免复制粘贴以重新构造

dom angular html

mackycheese21 · 技术社区 · 6 年前

所以我的HTML如下所示:

<div>
    <div>Lots of stuff that only appears in this component #1</div>
    <div>Lots of stuff that only appears in this component #2</div>
    <div>Lots of stuff that only appears in this component #3</div>
    <div>Lots of stuff that only appears in this component #4</div>
</div>

目前我正在研究CSS和布局,但这意味着我会不断地重新构建DOM:

<div>
    <div>
        <div>Lots of stuff that only appears in this component #1</div>
        Lots of stuff that only appears in this component #2
        <div>Lots of stuff that only appears in this component #3</div>
        Lots of stuff that only appears in this component #4
    </div>
</div>

或者类似的。

我看了看 ng-template 但这似乎只适用于 ngIf 和 ngSwitch .

我真正想要的是这样的东西,在这里我不需要每次布局更改时都重新复制所有内容。顺便说一句,假设我不能创建一个新组件并将其移动到那个新组件中。

<div>
    <div copyFrom="#1"></div>
    <div>
        <div copyFrom="#2"></div>
        <div copyFrom="#3"></div>
    </div>
    <div copyFrom="#4"></div>
</div>
<div no-display name="#1">Lots of stuff that only appears in this component #1</div>
<div no-display name="#2">Lots of stuff that only appears in this component #2</div>
<div no-display name="#3">Lots of stuff that only appears in this component #3</div>
<div no-display name="#4">Lots of stuff that only appears in this component #4</div>

有没有一种方法可以这样做,这样我就不必复制粘贴内容,而只需复制粘贴对内容的引用?

我用的是角7.1.4。

只是因为,因为我不知道你需要什么来帮助我,这是 ng --version :

Angular CLI: 7.1.4
Node: 11.6.0
OS: darwin x64
Angular: 7.1.4

你在找 NgTemplateOutlet

<div>
  <ng-container *ngTemplateOutlet="template1"></ng-container>
    <div>
      <ng-container *ngTemplateOutlet="template2"></ng-container>
      <ng-container *ngTemplateOutlet="template3"></ng-container>
    </div>
  <ng-container *ngTemplateOutlet="template4"></ng-container>
</div>

<ng-template #template1> ... </ng-template>
<ng-template #template2> ... </ng-template>
<ng-template #template3> ... </ng-template>
<ng-template #template4> ... </ng-template>
