Question

嘿我想在cordova上检查我的网络状态。当我的状态是 4g，3g，没有网络时，我的应用会提供正确的警报，但是在wifi上它表示连接未知。

        function init() {
            document.addEventListener("deviceready", onDeviceReady, false);
        }

        function onDeviceReady() {
            checkConnection();
        }
        function checkConnection() {
            var networkState = navigator.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.CELL]     = 'Cell generic connection';
            states[Connection.NONE]     = 'No network connection';

            alert('Connection type: ' + states[networkState]);
        }
    </script>

<body onload="init()">

        </div>
    </div>
</body>

有趣的是，我已经尝试了关于API文档的完整示例（即使我的代码与示例几乎相同） http://cordova.apache.org/docs/en/3.1.0/cordova_connection_connection.md.html#Connection

这里也发生了同样的错误。以防我分享我的设备信息。

我的手机：Sony Xperia Z. 型号：C6603 Android版本：4.2.2 编号：10.31.A.2.67

当wifi打开时，Cordova应用程序显示“连接类型未知”
