Angular 4：ngComponentOutlet - 数据绑定

Question

我正在尝试将数据绑定到 Angular 4 中的 ng-container。 组件加载正常，但是当我添加 [componentData]="testing" 时出现错误

<ng-container *ngComponentOutlet="components.name"  [componentData]="testing">
</ng-container>

错误

Error: Template parse errors:
Can't bind to 'componentData' since it isn't a known property of 'ng-container'.
1. If 'componentData' is an Angular directive, then add 'CommonModule' to the '@NgModule.imports' of this component.
2. To allow any property add 'NO_ERRORS_SCHEMA' to the '@NgModule.schemas' of this component. ("'Textarea' ">
                                      <ng-container *ngComponentOutlet="widget.widgetComponent.component"  [ERROR ->][componentData]="testing">
                                      </ng-container>
                            </div>

真的不能绑定数据到ngComponentOutlet吗？

Answer 1

要解决此问题，您可以创建自定义组件

'custom-ng-container'

@Input() componentName : any;
@Input() componentData : any[];

HTML 看起来像

<ng-container *ngComponentOutlet="componentName" >

</ng-container>

你应该在你的父组件中使用

<custom-ng-container [componentName]="components.name"  [componentData]="testing"> </custom-ng-container>
