Introduction of InAppBrowser :

Here we learn “How to use InAppBrowser Plugin in ionic4“, in which we check opening any browser in our app.

Output Example –

Benefits of using InAppBrowser:

• Generally if we want to open any site then we leave the app, so this is solution of that problem.
• Users can view web pages without leaving app.
• This plugin provide a web browser view within your app, so user don’t feel bad.
• Syntax –

Syntax: var ref = cordova.InAppBrowser.open(url, target, options);
Example: var ref = cordova.InAppBrowser.open(‘http://apache.org’, ‘_blank’, ‘location=yes’);

Explanation of code –

• ref: Reference to the InAppBrowser window when the target is set to ‘_blank’. (InAppBrowser)
• url: The URL to load (String). Call encodeURI() on this if the URL contains Unicode characters.
• target: The target in which to load the URL, an optional parameter that defaults to (String).
• _self: Opens in the Cordova WebView if the URL is in the white list, otherwise it opens in the InAppBrowser.
• _blank: Opens in the InAppBrowser.
• _system: Opens in the system’s web browser.
• options: Options for the InAppBrowser. Optional, defaulting to: location=yes. (String)
• The options string must not contain any blank space, and each feature’s name/value pairs must be separated by a comma. Feature names are case insensitive.
• location: Set to yes or no to turn the InAppBrowser’s location bar on or off
• The InAppBrowser window behaves like a standard web browser, and can’t access Cordova APIs. For this reason, the InAppBrowser is recommended
• The InAppBrowser provides by default its own GUI controls for the user (back, forward, done).

Follow these steps for opening InAppBrowser Plugin.

Step 1:

Firstly we need to install the ionic cordova plugin.

npm install @ionic-native/in-app-browser

Step 2:

Here we are going to import the plugin, open app.module.ts and import the in-app browser.

import { InAppBrowser } from '@ionic-native/in-app-browser/ngx';
providers: [
StatusBar,
SplashScreen,
{provide: ErrorHandler, useClass: IonicErrorHandler},
InAppBrowser,
]</strong></span>

Step 3:

Now open the file where you want to implement this, for me it’s home.html

<button ion-button full color="primary (click)="openInAppBrowser(link)">open browser</button>

Step 4:

Now open home.ts

import { InAppBrowser,InAppBrowserOptions } from '@ionic-native/in-app-browser/ngx';
export class BrowserPage {
options : InAppBrowserOptions = {
location : 'no',<span style="color: #3366ff;"> //Or 'yes'</span>
presentationstyle : 'pagesheet',<span style="color: #3366ff;">//use for back to the app</span>
};
constructor(private iab: InAppBrowser){}
openInAppBrowser(url){
const browser = this.iab.create(url,'_blank',this.options);</pre>
<code>browser.executeScript(...); <span style="color: #3366ff;">//use to execute additional script</span>
browser.insertCSS(...); <span style="color: #3366ff;">//use to execute additional css</span>
browser.on(<span class="hljs-string">'loadstop'</span>).subscribe(<span class="hljs-function"><span class="hljs-params">event</span> =></span> {
   browser.insertCSS({ code: <span class="hljs-string">"body{color: red;"</span> });
});//<span class="hljs-string">loadstop - </span>identify when browser closed</code>
} }
