如何在ionic 3实时Firebase中从数据列表中删除特定数据

import { Injectable } from '@angular/core';
import { AngularFireDatabase, AngularFireObject } from '@angular/fire/database';

@Injectable()
export class FirebaseService {
  itemRef: AngularFireObject<any>;

  constructor(private db: AngularFireDatabase) {
    // 初始化Firebase配置
    const firebaseConfig = {
      // 在这里填写你的Firebase配置信息
    };

    // 初始化Firebase应用
    firebase.initializeApp(firebaseConfig);
  }

  // 其他Firebase操作方法...
}

deleteData(dataId: string): Promise<void> {
  return this.db.object(`/data/${dataId}`).remove();
}

import { Component } from '@angular/core';
import { FirebaseService } from '路径/firebase.service';

@Component({
  selector: 'app-your-component',
  templateUrl: 'your-component.html'
})
export class YourComponent {
  constructor(private firebaseService: FirebaseService) {}

  deleteData(dataId: string): void {
    this.firebaseService.deleteData(dataId)
      .then(() => {
        console.log('数据删除成功！');
      })
      .catch((error) => {
        console.error('数据删除失败：', error);
      });
  }
}
