使用PHONEGAP可访问性API检测手机是否在线/离线

Question

嗨,谢谢,提前,

我知道Phonegap有一个可达性API,我想知道如何使用它来检测手机是否连接到网络.

我发现的是:http://github.com/phonegap/mobile-spec/blob/master/tests/network.tests.js

我只是不知道如何使用它,或者它是否适合我的需要.

再次感谢.

使用最新更新,检查设备是否在线的方法已更改 - 请查看http://docs.phonegap.com/phonegap_connection_connection.md.html#Connection上的API文档.

以下是他们用作示例的代码:

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

// Wait for PhoneGap to load
// 
document.addEventListener("deviceready", onDeviceReady, false);

// PhoneGap is loaded and it is now safe to make calls PhoneGap methods
//
function onDeviceReady() {
    checkConnection();
}

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]);
}

</script>
