显示我过滤的数据

--我试过的--

 getData(){
    this.firebaseService.getUsers()
    .subscribe(result => {
      this.items = result;
      this.id_order_filltered_items = result;
      this.phone_filtered_items = result;
      this.heure_filtered_items = result;
      this.NOMchauffeu_filtered_items = result;

    })
  }
 ngOnInit() {
    this.getData();
    console.log('hey',this.searchValue)
  }
searchByName(){
  let value = this.searchValue.toLowerCase();
  this.firebaseService.searchUsers(value)
  .subscribe(result => {
    this.NOMchauffeu_filtered_items = result;
    this.items = this.combineLists(result, this.phone_filtered_items);
  })

    return this.db.collection('commandes',ref =>
    ref.orderBy('phone').startAt(value)).snapshotChanges();
   }

我真的很感激帮助 我是 Firebase 的新手

我不完全确定你在尝试什么，但你可以尝试这样的事情（还没有测试过）

命令

export interface commandes{
    items ?: any;
    id_order_filltered_items ?:any
    phone_filtered_items ?: any
    heure_filtered_items ?: any
    NOMchauffeu_filtered_items?:any
  }

..

commandes: Commandes

 ngOnInit() {
    this.commandes = myService.searchUsersByAge(10).subscribe(x => {this.commandes = x; console.log('hey',this.commandes)} )
    
  }

我的服务

 searchUsersByAge(value){
          return this.db.collection<commandes>('commandes', ref =>
                 ref.orderBy('phone').startAt(value)).snapshotChanges();)}
