Question

我目前正在研究sencha touch 2项目我希望在不杀死应用程序实例的情况下显示消息“无法访问Internet”如何使用sencha touch 2或通过phonegap实现此目的

Answer 1

你可以检查与phonegap的连接，如下所示

navigator.network.connection.type示例

<script type="text/javascript" charset="utf-8" src="cordova-2.0.0.js"></script>
<script type="text/javascript" charset="utf-8">

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

// Cordova is loaded and it is now safe to make calls Cordova 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>

对话框将报告网络状态。
