是否可以重复使用 <ng-content></ng-content> 在组件模板中？ Angular2

Question

I am curious is there any way to reuse twice ng-content in component? Or to assign it to variable inside component constructor?

Something like:

 @Component({ selector: "component" }) @View({ template: `<ng-content></ng-content> and again <ng-content></ng-content>` }) 

Answer 1

There is also an other way of doing it with the help of ng-template

Wrap the ng-content inside ng-template and use ngTemplateOutlet with ng-container

Example:

<ng-container *ngIf="YourCondition" *ngTemplateOutlet="content"></ng-container>
<ng-container *ngIf="!YourCondition" *ngTemplateOutlet="content"></ng-container>

<ng-template #content><ng-content></ng-content></ng-template>

Use this as,

<my-component>Anything</my-component>

Answer 2

Yes, i also found this.

<my-component> <div content-a> A </div> </my-component>

and in component:

<ng-content select="[content-a]"></ng-content>
