Question

我使用了Phonegap网站的这个模型，但他没有发出显示连接状态的警报。我想打开InAppBrowser我创建它如果它显示通过3G或wifi连接的互联网，如果没有它会发出警告警告用户。

    <script type="text/javascript" charset="utf-8">

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

    // device APIs are available
    //
    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]);
        }
