您需要在组件的ngOnDestroy挂钩方法中使用clearInterval方法.为此，您需要通过setInterval方法保存返回的值.

You need to use clearInterval method for this within the ngOnDestroy hook method of your component. For this you need to save the returned value by the setInterval method.

以下是示例:

ngOnInit() {
  this.battleInit();
  this.id = setInterval(() => {
    this.battleInit(); 
  }, 5000);
}

ngOnDestroy() {
  if (this.id) {
    clearInterval(this.id);
  }
}
