This plugin provides a web browser view that displays when calling cordova.InAppBrowser.open().
var ref = cordova.InAppBrowser.open('http://apache.org', '_blank', 'location=yes');
The cordova.InAppBrowser.open() function is defined to be a drop-in replacement
for the window.open() function. Existing window.open() calls can use the
InAppBrowser window, by replacing window.open:
window.open = cordova.InAppBrowser.open;
If you change the browsers window.open function this way, it can have unintended side
effects (especially if this plugin is included only as a dependency of another
plugin).
The InAppBrowser window behaves like a standard web browser,
and can't access Cordova APIs. For this reason, the InAppBrowser is recommended
if you need to load third-party (untrusted) content, instead of loading that
into the main Cordova webview. The InAppBrowser is not subject to the
whitelist, nor is opening links in the system browser.
The InAppBrowser provides by default its own GUI controls for the user (back,
forward, done).
cordova plugin add cordova-plugin-inappbrowser
If you want all page loads in your app to go through the InAppBrowser, you can
simply hook window.open during initialization. For example:
document.addEventListener("deviceready", onDeviceReady, false);
function onDeviceReady() {
window.open = cordova.InAppBrowser.open;
}
#### config.xml
- InAppBrowserStatusBarStyle [iOS only]: (string, options 'lightcontent', 'darkcontent' or 'default'. Defaults to 'default') set text color style for iOS. 'lightcontent' is intended for use on dark backgrounds. 'darkcontent' is only available since iOS 13 and intended for use on light backgrounds.
```
Opens a URL in a new InAppBrowser instance, the current browser
instance, or the system browser.
var ref = cordova.InAppBrowser.open(url, target, options);
- __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 _self. _(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.
All platforms support:
- __location__: Set to yes or no to turn the InAppBrowser's location bar on or off.
Android supports these additional options:
- __hidden__: set to yes to create the browser and load the page, but not show it. The loadstop event fires when loading is complete. Omit or set to no (default) to have the browser open and load normally.beforeload
- __beforeload__: set to enable the event to modify which pages are actually loaded in the browser. Accepted values are get to intercept only GET requests, post to intercept on POST requests or yes to intercept both GET & POST requests. Note that POST requests are not currently supported and will be ignored (if you set beforeload=post it will raise an error).yes
- __clearcache__: set to to have the browser's cookie cache cleared before the new window is openedyes
- __clearsessioncache__: set to to have the session cookie cache cleared before the new window is opened#00ff00
- __closebuttoncaption__: set to a string to use as the close button's caption instead of a X. Note that you need to localize this value yourself.
- __closebuttoncolor__: set to a valid hex color string, for example: , and it will change theyes
close button color from default, regardless of being a text or default X. Only has effect if user has location set to .yes
- __footer__: set to to show a close button in the footer similar to the iOS __Done__ button. #00ff00
The close button will appear the same as for the header hence use __closebuttoncaption__ and __closebuttoncolor__ to set its properties.
- __footercolor__: set to a valid hex color string, for example or #CC00ff00 (#aarrggbb) , and it will change the footer color from default.yes
Only has effect if user has __footer__ set to .yes
- __hardwareback__: set to to use the hardware back button to navigate backwards through the InAppBrowser's history. If there is no previous page, the InAppBrowser will close. The default value is yes, so you must set it to no if you want the back button to simply close the InAppBrowser.yes
- __hidenavigationbuttons__: set to to hide the navigation buttons on the location toolbar, only has effect if user has location set to yes. The default value is no.yes
- __hideurlbar__: set to to hide the url bar on the location toolbar, only has effect if user has location set to yes. The default value is no.#00ff00
- __navigationbuttoncolor__: set to a valid hex color string, for example: , and it will change the color of both navigation buttons from default. Only has effect if user has location set to yes and not hidenavigationbuttons set to yes.#00ff00
- __toolbarcolor__: set to a valid hex color string, for example: , and it will change the color the toolbar from default. Only has effect if user has location set to yes.yes

- __useWideViewPort__: Sets whether the WebView should enable support for the "viewport" HTML meta tag or should use a wide viewport. When the value of the setting is , the layout width is always set to the width of the WebView control in device-independent (CSS) pixels. When the value is yes and the page contains the viewport meta tag, the value of the width specified in the tag is used. If the page does not contain the tag or does not provide a width, then a wide viewport will be used. (defaults to yes).yes
- __fullscreen__: Sets whether the InappBrowser WebView is displayed fullscreen or not. In fullscreen mode, the status bar is hidden. Default value is .
iOS supports these additional options:
- __hidden__: set to yes to create the browser and load the page, but not show it. The loadstop event fires when loading is complete. Omit or set to no (default) to have the browser open and load normally.beforeload

var ref = cordova.InAppBrowser.open('http://apache.org', '_blank', 'location=yes');
var ref2 = cordova.InAppBrowser.open(encodeURI('http://ja.m.wikipedia.org/wiki/ハングル'), '_blank', 'location=yes');
At the moment the only supported target in OSX is _system.
_blank and _self targets are not yet implemented and are ignored silently. Pull requests and patches to get these to work are greatly appreciated.
Since the introduction of iPadOS 13, iPads try to adapt their content mode / user agent for the optimal browsing experience. This may result in iPads having their user agent set to Macintosh, making it hard to detect them as mobile devices using user agent string sniffing. You can change this with the PreferredContentMode preference in config.xml.
`xml`
The example above forces the user agent to contain iPad. The other option is to use the value desktop to turn the user agent to Macintosh.
- Plugin is implemented via iframe,
- Navigation history (back and forward buttons in LocationBar) is not implemented.

You can use this plugin to show helpful documentation pages within your app. Users can view online help documents and then close them without leaving the app.
Here's a few snippets that show how you do this.
* Give users a way to ask for help.
* Load a help page.
* Let users know that you're getting their page ready.
* Show the help page.
* Handle page errors.
There's lots of ways to do this in your app. A drop down list is a simple way to do that.
`html
`
Gather the users choice in the onDeviceReady function of the page and then send an appropriate URL to a helper function in some shared library file. Our helper function is named showHelp() and we'll write that function next.
`javascript
$('#help-select').on('change', function (e) {
var url;
switch (this.value) {
case "article":
url = "https://cordova.apache.org/docs/en/latest/"
+ "reference/cordova-plugin-inappbrowser/index.html";
break;
case "video":
url = "https://youtu.be/F-GlVrTaeH0";
break;
case "search":
url = "https://www.google.com/#q=inAppBrowser+plugin";
break;
}
showHelp(url);
});
`
We'll use the open function to load the help page. We're setting the hidden property to yes so that we can show the browser only after the page content has loaded. That way, users don't see a blank browser while they wait for content to appear. When the loadstop event is raised, we'll know when the content has loaded. We'll handle that event shortly.
`javascript
function showHelp(url) {
var target = "_blank";
var options = "location=yes,hidden=yes";
inAppBrowserRef = cordova.InAppBrowser.open(url, target, options);
inAppBrowserRef.addEventListener('loadstart', loadStartCallBack);
inAppBrowserRef.addEventListener('loadstop', loadStopCallBack);
inAppBrowserRef.addEventListener('loaderror', loadErrorCallBack);
}
`
Because the browser doesn't immediately appear, we can use the loadstart event to show a status message, progress bar, or other indicator. This assures users that content is on the way.
`javascript
function loadStartCallBack() {
$('#status-message').text("loading please wait ...");
}
`
When the loadstopcallback event is raised, we know that the content has loaded and we can make the browser visible. This sort of trick can create the impression of better performance. The truth is that whether you show the browser before content loads or not, the load times are exactly the same.
`javascript
function loadStopCallBack() {
if (inAppBrowserRef != undefined) {
inAppBrowserRef.insertCSS({ code: "body{font-size: 25px;}" });
$('#status-message').text("");
inAppBrowserRef.show();
}
}
`
You might have noticed the call to the insertCSS function. This serves no particular purpose in our scenario. But it gives you an idea of why you might use it. In this case, we're just making sure that the font size of your pages have a certain size. You can use this function to insert any CSS style elements. You can even point to a CSS file in your project.
Sometimes a page no longer exists, a script error occurs, or a user lacks permission to view the resource. How or if you handle that situation is completely up to you and your design. You can let the browser show that message or you can present it in another way.
We'll try to show that error in a message box. We can do that by injecting a script that calls the function loadErrorCallBack(params) { $('#status-message').text(""); var scriptErrorMesssage = inAppBrowserRef.executeScript({ code: scriptErrorMesssage }, executeScriptCallBack); inAppBrowserRef.close(); inAppBrowserRef = undefined; } function executeScriptCallBack(params) { if (params[0] == null) { $('#status-message').text( } iab.open('local-url.html'); // loads in the Cordova WebView iab.open('http://whitelisted-url.com'); // loads in the Cordova WebView iab.open('http://whitelisted-url.com', 'random_string', 'location=no'); // loads in the InAppBrowser, no location bar iab.open('http://url-that-fails-whitelist.com'); // loads in the InAppBrowseralert function. That said, this won't work in browsers on Windows devices so we'll have to look at the parameter of the executeScript callback function to see if our attempt worked. If it didn't work out for us, we'll just show the error message in a on the page.`javascript`
"alert('Sorry we cannot open that page. Message from the server is : "
+ params.message + "');"
"Sorry we couldn't open that page. Message from the server is : '"
+ params.message + "'");
