我正在尝试使用角材料(7.0)选择列表as described here。
页面上的示例代码段为
<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>
在TS文件中定义了typesOfShoes
,如其代码段所述:
export class HomeComponent implements OnInit {
typesOfShoes: string[] = ['Boots', 'Clogs', 'Loafers', 'Moccasins', 'Sneakers'];
constructor() {}
ngOnInit() {}
}
对我来说很有道理,但是当我尝试编译时,出现了错误:
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
导入了我的应用模块。
我没有其他与要导入的列表选项相关的模块。
我在这里想念什么?
答案 0 :(得分:0)
在BrowserModule
中导入CommonModule
(如果是子模块,则导入@NgModule()
:
import {BrowserModule} from '@angular/common';
@NgModule({
imports: [BrowserModule],
})
