最佳答案
确保您在 mat-option
中提供的阵列中有图像。 ;然后,创建一个图像标签并为其提供图像源。
相关 HTML :
<h4>Basic mat-select with images</h4>
<mat-form-field>
<mat-label>Favorite food</mat-label>
<mat-select>
<mat-option *ngFor="let food of foods" [value]="food.value">
<img src='{{food.img}}'> {{food.viewValue}}
</mat-option>
</mat-select>
</mat-form-field>
相关 TS :
import { Component } from '@angular/core';
export interface Food {
value: string;
viewValue: string;
img: string;
}
@Component({
selector: 'select-overview-example',
templateUrl: 'select-overview-example.html',
styleUrls: ['select-overview-example.css'],
})
export class SelectOverviewExample {
foods: Food[] = [
{ value: 'steak-0', viewValue: 'Steak', img: 'https://www.akberiqbal.com/favicon-32x32.png' },
{ value: 'pizza-1', viewValue: 'Pizza', img: 'https://www.akberiqbal.com/favicon-16x16.png' },
{ value: 'tacos-2', viewValue: 'Tacos', img: 'https://www.akberiqbal.com/favicon-96x96.png' }
];
}
