ionin3引入外部頁面或者h5文件

方法一:iframe

iframe 元素會創建包含另外一個文檔的內聯框架（即行內框架）。

常用的屬性：

舉個例子說明：

    <iframe  src="assets/chaxun/index.html" width="100%" height="100%" scrolling="yes"></iframe>

這個index.html是一個h5頁面。

缺點是：與ionic自身框架有很多地方衝突

第二種方法：Themeable Browser【不僅可以打開，還是設計樣式】

1.安裝

ionic cordova plugin add cordova-plugin-themeablebrowser
npm install --save @ionic-native/themeable-browser

2.在app.module中引入

import { ThemeableBrowser} from '@ionic-native/themeable-browser';
  providers: [
    StatusBar,
    SplashScreen,
    ThemeableBrowser,
    {provide: ErrorHandler, useClass: IonicErrorHandler}
  ]

3.使用

//引入
import { ThemeableBrowser} from '@ionic-native/themeable-browser';
//設置選項和路徑
  private options = {
    statusbar: {
      color: '#ffffffff'
    },
    toolbar: {
      height: 44,
      color: '#f0f0f0ff'
    },
    title: {
      color: '#003264ff',
      showPageTitle: true
    },
    backButton: {
      image: 'back',
      imagePressed: 'back_pressed',
      align: 'left',
      event: 'backPressed'
    },
    forwardButton: {
      image: 'forward',
      imagePressed: 'forward_pressed',
      align: 'left',
      event: 'forwardPressed'
    },
    closeButton: {
      image: 'close',
      imagePressed: 'close_pressed',
      align: 'left',
      event: 'closePressed'
    },
    customButtons: [
      {
        image: 'share',
        imagePressed: 'share_pressed',
        align: 'right',
        event: 'sharePressed'
      }
    ],
    menu: {
      image: 'menu',
      imagePressed: 'menu_pressed',
      title: 'Test',
      cancel: 'Cancel',
      align: 'right',
      items: [
        {
          event: 'helloPressed',
          label: 'Hello World!'
        },
        {
          event: 'testPressed',
          label: 'Test!'
        }
      ]
    },
    backButtonCanClose: true
  };
  url: string = 'http://www.baidu.com';
  constructor(public navCtrl: NavController,private themeableBrowser: ThemeableBrowser) {
    
  }
//Creates a browser instance
       let browser = this.themeableBrowser.create(this.url, '_self', this.options);
