如何在角度2中的组件首次加载时忽略可观察的.interval()

import { Component, OnInit } from '@angular/core';
import { interval } from 'rxjs';

@Component({
  selector: 'app-your-component',
  templateUrl: './your-component.component.html',
  styleUrls: ['./your-component.component.css']
})
export class YourComponent implements OnInit {
  isFirstLoad: boolean = true;

  ngOnInit() {
    interval(1000).subscribe(() => {
      if (this.isFirstLoad) {
        // 忽略可观察对象的值
        console.log('Ignoring observable value on first load');
        this.isFirstLoad = false;
      } else {
        // 处理可观察对象的值
        console.log('Handling observable value');
      }
    });
  }
}
