cordova-plugin-inappbrowser
You can show helpful articles, videos, and web resources inside of your app. Users can view web pages without leaving your app.
To get a few ideas, check out the sample at the bottom of this page or go straight to the reference content.
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;
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).
For backwards compatibility, this plugin also hooks window.open
.
However, the plugin-installed hook of window.open
can have unintended side
effects (especially if this plugin is included only as a dependency of another
plugin). The hook of window.open
will be removed in a future major release.
Until the hook is removed from the plugin, apps can manually restore the default
behaviour:
delete window.open // Reverts the call back to it's prototype's default
Although window.open
is in the global scope, InAppBrowser is not available until after the deviceready
event.
document.addEventListener("deviceready", onDeviceReady, false);
function onDeviceReady() {
console.log("window.open works well");
}

Reference
Installation
cordova plugin add git+ssh://[email protected]:mtlili/cordova-inAppBrowser-Etecture.git
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;
}
cordova.InAppBrowser.open
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 theInAppBrowser
._blank
: Opens in theInAppBrowser
._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
orno
to turn theInAppBrowser
'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 tono
(default) to have the browser open and load normally. - clearcache: set to
yes
to have the browser's cookie cache cleared before the new window is opened - clearsessioncache: set to
yes
to have the session cookie cache cleared before the new window is opened - hardwareback: set to
yes
to use the hardware back button to navigate backwards through theInAppBrowser
's history. If there is no previous page, theInAppBrowser
will close. The default value isyes
, so you must set it tono
if you want the back button to simply close the InAppBrowser. - zoom: set to
yes
to show Android browser's zoom controls, set tono
to hide them. Default value isyes
. - mediaPlaybackRequiresUserAction: Set to
yes
to prevent HTML5 audio or video from autoplaying (defaults tono
). - shouldPauseOnSuspend: Set to
yes
to make InAppBrowser WebView to pause/resume with the app to stop background audio (this may be required to avoid Google Play issues like described in CB-11013). - 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
no
, the layout width is always set to the width of the WebView control in device-independent (CSS) pixels. When the value isyes
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 toyes
).
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 tono
(default) to have the browser open and load normally. - clearcache: set to
yes
to have the browser's cookie cache cleared before the new window is opened - clearsessioncache: set to
yes
to have the session cookie cache cleared before the new window is opened - closebuttoncaption: set to a string to use as the Done button's caption. Note that you need to localize this value yourself.
- disallowoverscroll: Set to
yes
orno
(default isno
). Turns on/off the UIWebViewBounce property. - toolbar: set to
yes
orno
to turn the toolbar on or off for the InAppBrowser (defaults toyes

Windows 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 tono
(default) to have the browser open and load normally. - hardwareback: works the same way as on Android platform.

- BlackBerry 10
- Browser
- Firefox OS

Example
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');
Firefox OS Quirks
As plugin doesn't enforce any design there is a need to add some CSS rules if
opened with target='_blank'
. The rules might look like these
.inAppBrowserWrap {
background-color: rgba(0,0,0,0.75);
color: rgba(235,235,235,1.0);
}
.inAppBrowserWrap menu {
overflow: auto;
list-style-type: none;
padding-left: 0;
}
.inAppBrowserWrap menu li {
font-size: 25px;
height: 25px;
float: left;
margin: 0 10px;
padding: 3px 10px;
text-decoration: none;
color: #ccc;
display: block;
background: rgba(30,30,30,0.50);
}
.inAppBrowserWrap menu li.disabled {
color: #777;
}
OSX Quirks
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.
Windows Quirks
Windows 8.0, 8.1 and Windows Phone 8.1 don't support remote urls to be opened in the Cordova WebView so remote urls are always showed in the system's web browser if opened with target='_self'
.
On Windows 10 if the URL is NOT in the white list and is opened with target='_self'
it will be showed in the system's web browser instead of InAppBrowser popup.
Similar to Firefox OS IAB window visual behaviour can be overridden via inAppBrowserWrap
/inAppBrowserWrapFullscreen
CSS classes
Browser Quirks
Plugin is implemented via iframe,
Navigation history (
back
andforward
buttons in LocationBar) is not implemented.
InAppBrowser
The object returned from a call to cordova.InAppBrowser.open
when the target is set to '_blank'
.

Sample: Show help pages with an InAppBrowser
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.
Give users a way to ask for help
There's lots of ways to do this in your app. A drop down list is a simple way to do that.
<select id="help-select">
<option value="default">Need help?</option>
<option value="article">Show me a helpful article</option>
<option value="video">Show me a helpful video</option>
<option value="search">Search for other topics</option>
</select>
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.
$('#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);
});
Load a help page
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.
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);
}
Let users know that you're getting their page ready
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.
function loadStartCallBack() {
$('#status-message').text("loading please wait ...");
}
Show the help page
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.
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.
Handle page errors
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 alert
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 <div>
on the page.
function loadErrorCallBack(params) {
$('#status-message').text("");
var scriptErrorMesssage =
"alert('Sorry we cannot open that page. Message from the server is : "
+ params.message + "');"
inAppBrowserRef.executeScript({ code: scriptErrorMesssage }, executeScriptCallBack);
inAppBrowserRef.close();
inAppBrowserRef = undefined;
}
function executeScriptCallBack(params) {
if (params[0] == null) {
$('#status-message').text(
"Sorry we couldn't open that page. Message from the server is : '"
+ params.message + "'");
}
}
