我在项目中使用table
组件。在第四栏中,我使用chips
显示玩家姓名,如下图所示:
这是我的问题:,如果我在players
字符串中添加2个或更多这样的名称:
players: 'Dwayne Jhonson,Tom cruise'
两个名称都显示在与上图相同的chip
中,但是我希望每个名称都显示在separate chips
中。
类似这样的东西:
组件代码: HTML:
<table mat-table [dataSource]="dataSource" class="mat-elevation-z8">
<ng-container matColumnDef="position">
<th mat-header-cell *matHeaderCellDef> No. </th>
<td mat-cell *matCellDef="let element"> {{element.position}} </td>
</ng-container>
<ng-container matColumnDef="name">
<th mat-header-cell *matHeaderCellDef> Name </th>
<td mat-cell *matCellDef="let element"> {{element.name}} </td>
</ng-container>
<ng-container matColumnDef="weight">
<th mat-header-cell *matHeaderCellDef> Weight </th>
<td mat-cell *matCellDef="let element"> {{element.weight}} </td>
</ng-container>
<ng-container matColumnDef="players">
<th mat-header-cell *matHeaderCellDef> Players </th>
<td mat-cell *matCellDef="let element">
<mat-chip-list>
<mat-chip>{{element.players}} </mat-chip>
</mat-chip-list>
</td>
</ng-container>
<tr mat-header-row *matHeaderRowDef="displayedColumns"></tr>
<tr mat-row *matRowDef="let row; columns: displayedColumns;"></tr>
</table>
TS:
import {Component} from '@angular/core';
export interface PeriodicElement {
name: string;
position: number;
weight: number;
players: string;
}
const ELEMENT_DATA: PeriodicElement[] = [
{position: 1, name: 'Hydrogen', weight: 1.0079, players: 'Dwayne Jhonson,Tom cruise'},
{position: 2, name: 'Helium', weight: 4.0026, players: 'Kevin peterson, Brett Lee'},
{position: 3, name: 'Lithium', weight: 6.941, players: 'Sachin Tendulakar, Yuvraj Sing'},
];
@Component({
selector: 'table-basic-example',
styleUrls: ['table-basic-example.css'],
templateUrl: 'table-basic-example.html',
})
export class TableBasicExample {
displayedColumns: string[] = ['position', 'name', 'weight', 'players'];
dataSource = ELEMENT_DATA;
}

如果可以更改模型,请尝试此操作。
将symbol
属性声明为string
数组:
export interface PeriodicElement {
....
symbol: string[];
}
然后类似地更改您的数据:
const ELEMENT_DATA: PeriodicElement[] = [
{position: 1, name: 'Hydrogen', weight: 1.0079, symbol: ['Dwayne Jhonson','Tom cruise']},
{position: 2, name: 'Helium', weight: 4.0026, symbol: ['Kevin peterson', 'Brett Lee']},
...
]
最后在视图中,遍历符号元素以创建多个筹码:
<ng-container matColumnDef="symbol">
<th mat-header-cell *matHeaderCellDef> Players </th>
<td mat-cell *matCellDef="let element">
<mat-chip-list>
<span *ngFor="let symbols of element.symbol">
<mat-chip>{{symbols}} </mat-chip>
</span>
</mat-chip-list>
</td>
</ng-container>
如果不能更改模型 ,则需要创建一个函数,该函数将以symbol属性作为参数,并返回一个string
数组,其中strings
为由,
分割的原始字符串。然后,在视图中,您必须迭代该数组以生成芯片。
