尝试从Angular中的json数组获取特定数据时，我的方法只获取部分数据。

import { HttpClient } from '@angular/common/http';

constructor(private http: HttpClient) { }

getData() {
  return this.http.get('your-api-url');
}

dataArray: any[];

getData() {
  this.getData().subscribe((data: any[]) => {
    this.dataArray = data;
  });
}

getSpecificData(id: number) {
  return this.dataArray.find(item => item.id === id);
}

specificData: any;

ngOnInit() {
  this.getData();
  this.specificData = this.getSpecificData(1); // 传入特定的id值
}
