如何在ionic 3中使用复选框删除多个项目

projects: any[] = [
  { id: 1, name: '项目1' },
  { id: 2, name: '项目2' },
  { id: 3, name: '项目3' },
  // 其他项目...
];

selectedProjects: any[] = [];

<ion-list>
  <ion-item *ngFor="let project of projects">
    <ion-label>{{ project.name }}</ion-label>
    <ion-checkbox [(ngModel)]="selectedProjects" value="{{ project }}"></ion-checkbox>
  </ion-item>
</ion-list>

<button ion-button (click)="deleteSelectedProjects()">删除选中项目</button>

deleteSelectedProjects() {
  for (let project of this.selectedProjects) {
    const index = this.projects.indexOf(project);
    if (index > -1) {
      this.projects.splice(index, 1);
    }
  }
  this.selectedProjects = []; // 清空选中的项目数组
}
