The PhoneGap JavaScript library adds new properties to the window global object. One of them is the device property. The device property holds a reference for an object that describes the device. The following code sample shows how simple it is to use this object in order to get detailed information about the device.

<!DOCTYPE html>
<html>
    <head>
        <meta charset="utf-8" />
        <meta name="format-detection" content="telephone=no" />
        <meta name="viewport" content="user-scalable=no, initial-scale=1, maximum-scale=1, minimum-scale=1, width=device-width, height=device-height, target-densitydpi=device-dpi" />
        <link rel="stylesheet" type="text/css" href="css/index.css" />
        <title>Hello World</title>
    </head>
    <body>
    	<div id="msg">...</div>
        <script type="text/javascript" src="cordova.js"></script>
        <script type="text/javascript">
        	function onDeviceReady() 
        	{
        		var str = "<h1>information about the device</h1>";
        		str += "<h2>device.name="+device.name+"</h2>";
        		str += "<h2>device.version="+device.version+"</h2>";
        		str += "<h2>device.platform="+device.platform+"</h2>";
        		str += "<h2>device.uuid="+device.uuid+"</h2>";
        		str += "<h2>device.phonegap="+device.phonegap+"</h2>";
        		document.getElementById("msg").innerHTML = str;
        	}
        	document.addEventListener('deviceready', onDeviceReady, false);       	
        </script>
    </body>
</html>
