我是Ionic的初学者2.我想在点击列表项后将Json数据从一个页面传递到另一个页面.列表中的项目来自json,并且具有与每个项目相关联的特定ID.所以我想在特定项目的点击事件之后传递特定的id.
这是json链接:
1. http://factoryunlock.in//products借助此链接,我将在列表中显示产品
但是现在我想展示那个特定项目的细节.所以我使用这个链接
http://factoryunlock.in/products/1
我想在特定项目的点击事件后更改该ID(在链接2产品/ 1中).
这是我的Listview代码(Second.ts).
import { Component } from '@angular/core'; import { IonicPage,NavController,NavParams } from 'ionic-angular'; import { EarthquakesProvider } from '../../providers/earthquakes/earthquakes'; import { DetailsPage } from '../details/details'; import { ChartsPage } from '../charts/charts'; @IonicPage() @Component({ selector: 'page-second',templateUrl: 'second.html',providers: [EarthquakesProvider] }) export class SecondPage { public DateList: Array<Object>; constructor(public _navCtrl: NavController,public _earthquakes: EarthquakesProvider) { this.getEarthquakes(); } public Listitem(l) { this._navCtrl.push(DetailsPage ); } public openModal() { this._navCtrl.push(ChartsPage); } getEarthquakes() { this._earthquakes.loadEarthquakess().subscribe(res => { this.DateList = res.data; }); } }
这是我的提供者控制器:
import { Injectable } from '@angular/core'; import { Http } from '@angular/http'; import 'rxjs/add/operator/map'; @Injectable() export class EarthquakesProvider { constructor(public _http: Http) { console.log('Hello Earthquakes Provider'); } loadEarthquakess() { return this._http.get('http://factoryunlock.in/sundar/public/api/v1/products') .map(res => res.json()); } loadEarthquakesdetails() { return this._http.get('http://factoryunlock.in/sundar/public/api/v1/products/1') .map(res => res.json()); }
这是我的details.ts代码
import { Component } from '@angular/core'; import { IonicPage,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; constructor(public _navCtrl: NavController,public _earthquakes: EarthquakesProvider) { this.getEarthquakes(); } getEarthquakes() { this._earthquakes.loadEarthquakesdetails().subscribe(res => { this.DateList = res.data; console.log(res.data); }); } }
这是我的详细信息视图快照
列表视图页面
public Listitem(id) { this._navCtrl.push(DetailsPage,{id: id}); }
提供者控制者
loadEarthquakesdetails(id) { return this._http.get(`http://factoryunlock.in/sundar/public/api/v1/products/${id}`) .map(res => res.json()); }
Details.ts代码
import { Component } from '@angular/core'; import { IonicPage,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 => { this.DateList = res.data; console.log(res.data); }); } }
