如何以编程方式添加芯片，而不使用[(ngModel)]

<!-- 选择要添加的芯片 -->
<select (change)="selectChip($event.target.value)">
  <option value="chip1">芯片1</option>
  <option value="chip2">芯片2</option>
  <option value="chip3">芯片3</option>
</select>

<!-- 显示已添加的芯片列表 -->
<ul>
  <li *ngFor="let chip of addedChips">{{ chip }}</li>
</ul>

import { Component } from '@angular/core';

@Component({
  selector: 'app-chip',
  templateUrl: './chip.component.html',
  styleUrls: ['./chip.component.css']
})
export class ChipComponent {
  addedChips: string[] = [];

  selectChip(chip: string) {
    // 将选择的芯片添加到数组中
    this.addedChips.push(chip);
  }
}
