blackberry.polarmobile.childbrowser

This extension for the BlackBerry WebWorks SDK for Tablet OS provides a "child browser" mechanism for displaying external webpages within WebWorks applications.

Webpages hosted within this child browser run within a WebKit instance that is completely isolated and independent from the WebKit instance being used to host your core WebWorks app.

Installation

Clone this repository into a folder called blackberry.polarmobile.childbrowser/ within the bbwp/ext/ folder of your WebWorks SDK installation.

Compatibility

This extension has been tested with the BlackBerry WebWorks SDK for TabletOS v2.1.0.6.

Usage

Configuration

In the config.xml file of your WebWorks app, include the following feature element:

<feature id="blackberry.polarmobile.childbrowser" />

Code Sample

var browser = blackberry.polarmobile.childbrowser;

// view http://polarmobile.com
browser.loadURL("http://polarmobile.com");

// get the URL of the browser's current location
browser.getLocation();

// refresh the current page
browser.refresh();

// clear all cookies
browser.clearCookies();

// automatically close the browser in 10 seconds from now
setTimeout(function(){ browser.close(); }, 10000);

Basic Async Code Sample

var browser = blackberry.polarmobile.childbrowser;
var url = "http://twitter.com/gogibbons";
browser.loadURLAsync(
    url,
    function (result)
    {
        console.log("The current url is: " + result.data);
    },
    function ()
    {
        console.log("The browser has been closed");
    });

Async Code Sample Showing How To Obtain Facebook Credentials

var browser = blackberry.polarmobile.childbrowser;
var appID = "<insert numeric app ID here>";
var redirect = "https://www.facebook.com/connect/login_success.html";

var path = 'https://www.facebook.com/dialog/oauth?display=wap&scope=publish_actions,read_stream&';
var queryParams = ['client_id=' + appID, 'redirect_uri=' + redirect, 'response_type=token'];
var query = queryParams.join('&');
var url = path + query;
var browserIsOpen = true;
browser.loadURLAsync(
    url,  // URL to open in browser
    function (result){
        var url = result.data;
        if (url.substring(0, redirect.length) == redirect)
        {
            var fbAccessToken = url.match(/access_token=([^&]+)/)[1];
            localStorage.setItem('fbAccessToken', fbAccessToken);
            browserIsOpen = false;
            browser.close();
            browser.clearCookies();
            alert("You authenticated with Facebook");
        }
    },
    function ()
    {
        if (browserIsOpen)
        {
            alert("You closed the browser before we authenticated you!");
        }
    });
