简单的范例:
function checkConnection() {
	var networkState = navigator.network.connection.type;
	
	var states = {};
	states[Connection.UNKNOWN]  = 'Unknown connection';
	states[Connection.ETHERNET] = 'Ethernet connection';
	states[Connection.WIFI]     = 'WiFi connection';
	states[Connection.CELL_2G]  = 'Cell 2G connection';
	states[Connection.CELL_3G]  = 'Cell 3G connection';
	states[Connection.CELL_4G]  = 'Cell 4G connection';
	states[Connection.NONE]     = 'No network connection';
	
	alert('Connection type: ' + states[networkState]);
}
	
checkConnection();

<script type="text/javascript" charset="utf-8" src="phonegap.js"></script> 	
<script type="text/javascript" charset="utf-8">  

	// 等待加载PhoneGap
	document.addEventListener(“deviceready“, onDeviceReady, false);  

	// PhoneGap加载完毕,可以安全调用PhoneGap方法
	function onDeviceReady() { 
		checkConnection(); 
	}  

	function checkConnection() { 
		var networkState = navigator.network.connection.type; 		 

		var states = {}; 
		states[Connection.UNKNOWN]  = 'Unknown connection';
