带有参数的模态创建

将参数传递给模态与将值传递给 NavController 的方式类似。为此，我们正在改变 home.html 中的列表，以便在单击列表项并将所需参数作为第二个参数传递给 create 方法时打开模式。

Home.html 中

 <ion-list>
    <ion-item *ngFor="let datum of data" (click)="openModalwithNavParams(datum)">
      <h1>{{datum.name}}</h1>
    </ion-item>
  </ion-list>

Home.ts

import {EditProfilePage} from '../edit-profile/edit-profile';

  openModalwithNavParams(data){
    let modalWithNavParams = this.modalCtrl.create(EditProfilePage,{Data: data});
    modalWithNavParams.present();
  }

与其他视图类似，我们使用 NavParams 来检索从上一个视图发送的数据。

编辑 Profile.html

<ion-header>
  <ion-toolbar>
    <ion-title>
      Login
    </ion-title>
    <ion-buttons start>
      <button (click)="dismiss()">
        <span primary showWhen="ios">Cancel</span>
        <ion-icon name="md-close" showWhen="android,windows"></ion-icon>
      </button>
    </ion-buttons>
  </ion-toolbar>
</ion-header>
<ion-content padding>
  <h2>Welcome {{name}}</h2>
  <ion-list>
    <ion-item>
      <ion-label>Email</ion-label>
      <ion-input type="text" value={{email}}></ion-input>
    </ion-item>
    <ion-item>
      <ion-label>Mobile</ion-label>
      <ion-input type="number" value={{mobile}}></ion-input>
    </ion-item>
    <ion-item>
      <ion-label>Nickname</ion-label>
      <ion-input type="text" value={{nickname}}></ion-input>
    </ion-item>
  </ion-list>
  <button full (click)="dismiss()">Close</button>
</ion-content>

编辑 Profile.ts

import { Component } from '@angular/core';
import { ViewController, NavParams } from 'ionic-angular';
@Component({
  templateUrl: 'build/pages/edit-profile/edit-profile.html',
})
export class EditProfilePage {
  viewCtrl;
  navParams;
  data;
  name;
  email;
  mobile;
  nickname;
  constructor(viewCtrl: ViewController, navParams: NavParams) {
    this.viewCtrl = viewCtrl;
    this.navParams = navParams;
    this.data = this.navParams.get('Data');
    this.name = this.data.name;
    this.email = this.data.email;
    this.mobile = this.data.mobile;
    this.nickname = this.data.nickname;
    
  }
  dismiss(){
    this.viewCtrl.dismiss();
  }
}
