Cordova NetworkState在状态更新后不会更改

Question

我有以下代码。如果我启动wifi功能关闭（在我的选项卡上），我收到了警报。到现在为止还挺好。但是，如果我打开wifi然后，我仍然得到警报，我没有连接。

有什么想法吗？

    //Kontrolle, ob benötigtes Netzwerk vorhanden ist
    function checkNetwork()
    {
        network()

        if (networkState != 'none')
        {
            networkState = '';
            writeDataToFile();
        }
        else
        {
            alert('Bitte die Internetverbindung checken');
            networkState = '';
            checkNetwork()
        }
    }

    //Welches Netzwerk ist gerade vorhanden
    function network()
    {
        networkState = navigator.connection.type;

        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]);
    }
