clearinterval在ngOnDestroy()中不起作用

Question

我的ngOndestroy正在调用其他路由导航,但它没有在方法中执行clearInterval.我哪里弄错了？它在后台运行,而我在其他组件中.

timer:any;

ngOnInit() {
  this.timer= this.interval();
};

 ngOnDestroy(){
    clearInterval(this.timer);
   console.log("Inside Destroy");


 }

interval(){
  setInterval(()=>{
    this.getData();
  },20000)
}
 getData(){
   this.dataservice.getdata()
      .subscribe(users=>{
      this.datas=users;
      console.log(this.datas);
    })
 }

Answer 1

你忘了返回间隔的实例.

interval(){
  return setInterval(()=>{
    this.getData();
  },20000)
}
