Question

我想用2个不同的JSON文件填充智能表。使用属性Observable.forkjoin（）但它不会绑定。我该怎么做？请帮帮我

service.ts

＆＃13;

import {Injectable} from '@angular/core';
import { Http, Response, Headers, RequestOptions } from '@angular/http';
import { Observable } from 'rxjs/Rx';
@Injectable()
export class SmartTablesService {
  constructor(private http: Http) {
    
        }
        
        smartTableData = [];
//data/article.json
loadData() {
  console.log('loadData');
  Observable.forkJoin(
  this.http.get('http://192.168.0.100:8000/medical'),
  this.http.get('http://192.168.0.100:8000/cost'))
  .subscribe((data) => {
          setTimeout(() => {
              
              var contactData = [];
              $.each(data.map(res => res.json()), function (key, value) {
      //alert(data);
                //  alert(value.year);
              var tempData = value;
              alert(tempData.year);


                

                  contactData.push(tempData);
              });
              //alert(tempData.year);
              this.smartTableData = contactData;
          }, 1000);
      });
}
getData(): Promise<any> {
  console.log("Promise");
  this.loadData();
  return new Promise((resolve, reject) => {
      setTimeout(() => {
          console.log(this.smartTableData);
          resolve(this.smartTableData);
      }, 3000);
  });
}
}
