在Angular 7中删除选中复选框列表时，复选框不被勾选或取消勾选

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

@Component({
  selector: 'app-checkbox-list',
  template: `
    <div *ngFor="let item of items">
      <input type="checkbox" [(ngModel)]="item.checked" (change)="onCheckboxChange(item)">
      {{ item.name }}
    </div>
    <button (click)="deleteSelectedItems()">删除选中项</button>
  `
})
export class CheckboxListComponent {
  items = [
    { name: 'Item 1', checked: false },
    { name: 'Item 2', checked: false },
    { name: 'Item 3', checked: false }
  ];

  onCheckboxChange(item: any) {
    // 复选框状态变化时更新数据模型
    console.log(item.checked);
  }

  deleteSelectedItems() {
    // 删除选中项的逻辑
    this.items = this.items.filter(item => !item.checked);
  }
}
