我的组件模板中有以下内容:
<div *ngIf="user$ | async as user>...</div>
在上面div我想使用异步管道只订阅一次另一个observable,并user在整个模板中像上面一样使用它.例如,这样的事情是可能的:
<ng-template *ngIf="language$ | async as language>
<div *ngIf=" user$ | async as user>
<p>All template code that would use both {{user}} and {{language}} would go in between</p>
</div>
</ng-template>或者甚至可以在一个声明中合并？
