如何使用ngForTemplate包装模板? [英] How to wrap template using ngForTemplate?

问题描述

我尝试使用ngForTemplate作为自定义模板制作ListView组件

I try to make ListView component using ngForTemplate for custom templates

list-view.component.html

<div class="list-view">
    <template ngFor [ngForOf]="items" [ngForTemplate]="template">
    </template>
</div>

list-view.component.ts

@Component({
    selector: 'm-list-view',
    styleUrls: ['./list-view.component.less'],
    templateUrl: './list-view.component.html'
})

export class ListViewComponent {
    @Input() items: any[] = [];

    @ContentChild(TemplateRef)
    template: any;
}

当我这样使用它时:

<m-list-view [items]="categories">
    <template let-item="$implicit">
        **some HTML markup**
    </template>
</m-list-view>

结果是:

<m-list-view>
    <div class="list-view">
        **some HTML markup**
        **some HTML markup**
        **some HTML markup**
        ...
    </div>
</m-list-view>

但是我需要这个:

<m-list-view>
    <div class="list-view">
        <div class="list-view-item">**some HTML markup**</div>
        <div class="list-view-item">**some HTML markup**</div>
        <div class="list-view-item">**some HTML markup**</div>
        ...
    </div>
</m-list-view>

我该怎么做才能将每​​个列表视图项目模板包装在div.list-view-item中?

What should I do to wrap each list view item template in div.list-view-item?

推荐答案

更新Angular 5

ngOutletContext重命名为ngTemplateOutletContext

现在建议您使用以下语法:

It is now advised that you use the following syntax:

<div class="list-view">
  <div class="list-view-item" *ngFor="let item of items">
    <ng-container *ngTemplateOutlet="template; context: item">
    </ng-container>
  </div>
</div>

另请参见 https://github.com/angular/angular/blob/master/CHANGELOG.md#500-beta5-2017-08-29

原始

<div class="list-view">
  <div class="list-view-item" *ngFor="let item of items">
    <template [ngTemplateOutlet]="template" [ngOutletContext]="item"></template>
  </div>
</div>

另请参见 https://angular.io/docs/ts/latest/api/common/index/NgTemplateOutlet-directive.html
