import { Component } from '@angular/core';
import { IonicPage, NavController, NavParams } from 'ionic-angular';
import { EarthquakesProvider } from '../../providers/earthquakes/earthquakes';


@IonicPage()
@Component({
  selector: 'page-details',
  templateUrl: 'details.html',
  providers: [EarthquakesProvider]
})
export class DetailsPage {

   // public DateList: Array<Object>;

    item: any;
     id: number;
    constructor(public _navCtrl: NavController, public _earthquakes: EarthquakesProvider, public navParams: NavParams) {

         this.id = navParams.get('id');


    }
    ionViewDidLoad() {
        this.getEarthquakes(this.id);
}
    getEarthquakes(id) {
        this._earthquakes.loadEarthquakesdetails(id).subscribe(res => {
          
            
        });
    }
