# 背景 #

在使用Ionic开发APP时，为了在应用中打开或嵌入外部服务器页面，就需要用到浏览器插件，在Ionic官网的原生功能介绍中，提供了2种使用浏览的方式，分别为：  
Themeable Browser，官网地址：[https://ionicframework.com/docs/native/themeable-browser/][https_ionicframework.com_docs_native_themeable-browser]  
In App Browser，官网地址：[https://ionicframework.com/docs/native/in-app-browser/][https_ionicframework.com_docs_native_in-app-browser]

# 使用方式 #

下面我们就写一个demo，来使用这2个插件。  
首先先用一下指令创建一个ionic应用

ionic start test3 tabs

然后

cd test3

## 使用Themeable Browser ##

1、安装插件

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

2、在app.module.ts中导入，并加入到providers中

import {  ThemeableBrowser } from '@ionic-native/themeable-browser/ngx';
    
    @NgModule({ 
    	providers: [
    		ThemeableBrowser,
    	],
    })
    export class AppModule { }

具体如下图：

3、在页面中使用Themable Browser

3.1 在页面的ts文件头部导入Themable Browser

import {  ThemeableBrowser, ThemeableBrowserOptions, ThemeableBrowserObject } from '@ionic-native/themeable-browser/ngx';

3.2 在页面的ts文件中的构造方法中注入ThemeableBrowser

constructor(private themeableBrowser: ThemeableBrowser) {  }

3.3 在页面的ts文件中写一个处理方法

public buttonClick() { 
      const options: ThemeableBrowserOptions = { 
         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
       }
    
       const browser: ThemeableBrowserObject = this.themeableBrowser.create('https://www.baidu.com', '_self', options);
    
     }

3.4 在页面的html文件中添加一个按钮，并把上面写的方法绑定到click事件上，如下：

<ion-button (click)="buttonClick()">Test ThemeableBrowser</ion-button>

## 使用In App Browser ##

在Ionic中使用In App Browser的方式与使用ThemeableBrowser的方式很类似，下面介绍一下。  
1、安装插件

ionic cordova plugin add cordova-plugin-inappbrowser
    npm install @ionic-native/in-app-browser

2、在app.module.ts中导入，并加入到providers中

import {  InAppBrowser } from '@ionic-native/in-app-browser/ngx';
    
    @NgModule({ 
    	providers: [
    		InAppBrowser,
    	],
    })
    export class AppModule { }

具体如下图：

3、在页面中使用In App Browser

3.1 在页面的ts文件头部导入In App Browser

import {  InAppBrowser } from '@ionic-native/in-app-browser/ngx';

3.2 在页面的ts文件中的构造方法中注入InAppBrowser

constructor(private iab: InAppBrowser) {  }

3.3 在页面的ts文件中写一个处理方法

public buttonClick2() { 
        this.iab.create('https://www.baidu.com', '_self', 'location=no');
    }

3.4 在页面的html文件中添加一个按钮，并把上面写的方法绑定到click事件上，如下：

<ion-button (click)="buttonClick2()">Test In-App-Browser</ion-button>

      public buttonClick() { 
        console.log('test!!!');
        
        const options: ThemeableBrowserOptions = {

      public buttonClick2() { 
        this.iab.create('https://www.baidu.com', '_self', 'location=no');
      }
    }

3、html文件代码

          Tab 1
        </ion-title>
      </ion-toolbar>

4、点击 TEST IN-APP-BROWSER按钮，如下图：

# 总结 #

默认超链接打开浏览器的方式其实是开启了另一个应用，当屏幕滑动执行返回操作时不会回到第一个页面，而ThemeableBrowser和InAppBrowser都可以实现返回时自动回到第一个页面，但是ThemeableBrowser能够对浏览器的导航栏，菜单，标题等进行精确设定，相比InAppBrowser功能更强一些。
