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 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;
}

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 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 the value below:

  • location: Set to yes or no to turn the InAppBrowser's location bar on or off.

  Android only:

  • 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.
  • 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
  • zoom: set to yes to show Android browser's zoom controls, set to no to hide them. Default value is yes.
  • hardwareback: set to yes 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.
  • mediaPlaybackRequiresUserAction: Set to yes to prevent HTML5 audio or video from autoplaying (defaults to no).
  • 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).

  iOS only:

  • 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 or no (default is no). Turns on/off the UIWebViewBounce property.
  • 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.
  • 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
  • toolbar: set to yes or no to turn the toolbar on or off for the InAppBrowser (defaults to yes)
  • enableViewportScale: Set to yes or no to prevent viewport scaling through a meta tag (defaults to no).
  • mediaPlaybackRequiresUserAction: Set to yes to prevent HTML5 audio or video from autoplaying (defaults to no).
  • allowInlineMediaPlayback: Set to yes or no to allow in-line HTML5 media playback, displaying within the browser window rather than a device-specific playback interface. The HTML's video element must also include the webkit-playsinline attribute (defaults to no)
  • keyboardDisplayRequiresUserAction: Set to yes or no to open the keyboard when form elements receive focus via JavaScript's focus() call (defaults to yes).
  • suppressesIncrementalRendering: Set to yes or no to wait until all new view content is received before being rendered (defaults to no).
  • presentationstyle: Set to pagesheet, formsheet or fullscreen to set the presentation style (defaults to fullscreen).
  • transitionstyle: Set to fliphorizontal, crossdissolve or coververtical to set the transition style (defaults to coververtical).
  • toolbarposition: Set to top or bottom (default is bottom). Causes the toolbar to be at the top or bottom of the window.

  Windows only:

  • 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.
  • fullscreen: set to yes to create the browser control without a border around it. Please note that if location=no is also specified, there will be no control presented to user to close IAB window.
  • hardwareback: works the same way as on Android platform.

Supported Platforms

• Amazon Fire OS
• Android
• BlackBerry 10
• Firefox OS
• iOS
• OSX
• Windows 8 and 8.1
• Windows Phone 7 and 8
• Browser

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 and forward buttons in LocationBar) is not implemented.

InAppBrowser

The object returned from a call to cordova.InAppBrowser.open when the target is set to '_blank'.

Methods

• addEventListener

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 + "'");
    }

}
