我需要显示位于对象数组中的数组质量.我尝试使用下面的代码在ngFor中调用它.我使用ngFor有什么问题吗?
import { Component} from '@angular/core'; @Component({ selector: 'my-app',template: `<table> <thead> <tr> <th>Name</th> <th>Quality1</th> <th>Quality2</th> </tr> </thead> <tbody> <tr *ngFor"let item of people"> <td>{{item.Name}}</td> <td *ngFor"let item of people.quality">item.quality1</td> <td *ngFor"let item of people.quality">item.quality2/td> </tr> </tbody> </table> }) export class AppComponent{ people: any = [{Name:"John",quality:[{quality1: "nice",quality2: "humble"}]},{Name:"Dave",quality:[{quality1: "kind",quality2: "caring"}]} ]; }
截至目前,只有名字出现在表格中,但我也希望质量出现.
解决方法
您可以使用< ng-container>将几个节点与* ngFor组合而不向DOM引入另一个元素:
<ng-container *ngFor"let item of people.quality"> <td>item.quality1</td> <td>item.quality2/td> </ng-container>
