我正在尝试使用角度材质(7.0)选择列表as described here。
页面上的示例代码片段是
<mat-selection-list #shoes>
<mat-list-option *ngFor="let shoe of typesOfShoes">
{{shoe}}
</mat-list-option>
</mat-selection-list>
<p>
Options selected: {{shoes.selectedOptions.selected.length}}
</p>
使用TS文件中定义的typesOfShoes
,如其代码片段中所述:
export class HomeComponent implements OnInit {
typesOfShoes: string[] = ['Boots', 'Clogs', 'Loafers', 'Moccasins', 'Sneakers'];
constructor() {}
ngOnInit() {}
}
对我来说是有意义的,但是当我尝试编译时,我得到了错误
ERROR in: Can't bind to 'ngForOf' since it isn't a known property of 'mat-list-option'.
1. If 'mat-list-option' is an Angular component and it has 'ngForOf' input,
then verify that it is part of this module.
2. If 'mat-list-option' is a Web Component then add 'CUSTOM_ELEMENTS_SCHEMA'
to the '@NgModule.schemas' of this component to suppress this message.
etc.
我已经将MatListModule
导入到我的应用程序模块中。
我看不到与要导入的列表选项相关的其他模块。
这里我漏掉了什么?

在@NgModule()
中导入BrowserModule
(如果是子模块,则导入CommonModule
import { BrowserModule } from '@angular/platform-browser';
@NgModule({
imports: [BrowserModule],
})
