1.8 ionic3入门——测滑菜单(side menu)中的界面跳转

(1)如1.3 所写,测滑菜单写在app.html,所以测滑菜单中的各个按钮的实现就在app.component.ts中写了,如果像其他普通界面一样在app.component.ts中引入NavController并在构造函数constructor中声明public navCtrl:NavController就会报错,那么,在app.html中正确进行界面跳转的方法为
(2)引入ViewChild和Nav

import { Component,ViewChild } from '@angular/core';
import { Platform,Nav} from 'ionic-angular';

(3)声明

  @ViewChild(Nav) nav: Nav;

(4)跳转

this.nav.push(SettingsPage);

(5)全部代码

import { Component,ViewChild } from '@angular/core';
import { Platform,Nav} from 'ionic-angular';
import { StatusBar } from '@ionic-native/status-bar';
import { SplashScreen } from '@ionic-native/splash-screen';

import { TabsPage } from '../pages/tabs/tabs';
import { LoginPage } from '../pages/login/login';
import { SettingsPage } from '../pages/settings/settings';

@Component({
  templateUrl: 'app.html'
})
export class MyApp {
  

   // 父组件中使用@ViewChild拿到子组件的变量和方法(父组件可调用子组件的方法和变量)
  // 这里引入的是app.html <ion-nav>
  @ViewChild(Nav) nav: Nav;

  rootPage:any = TabsPage;
  
  constructor(platform: Platform, statusBar: StatusBar, splashScreen: SplashScreen) {
    platform.ready().then(() => {
      statusBar.styleDefault();
      splashScreen.hide();
    });
  }

  push_mysettings(){
    this.nav.push(SettingsPage);
  }
}
