Question

请帮忙。我有以下无限运行的功能：

    // Check the connection state of the device
    function checkConnection() {

        var networkState = "";
        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';

        if (states[networkState] === 'No network connection') {
            noNetworkAlertCreate();
        } else {
            noNetworkAlertRemove();
        }

        checkConnection();
    }

设备准备就绪后，会调用此功能：

    // Device is ready let's do this
    function onDeviceReady() {
        checkConnection();
    }

该函数已正确循环，但连接状态在某种程度上不会随每个循环更新。如果状态首次注册为WIFI，则在再次运行时不会更新，并且即使已禁用WIFI，也会再次注册为WIFI。

有什么建议吗？

非常感谢

ondeviceready只会在cordova满载时触发一次。当“在线”和“离线”等不同事件发生时，您需要调用相同的功能。：

// Device is ready let's do this
function onDeviceReady() {
    checkConnection();
}

document.addEventListener("deviceready", onDeviceReady, false);
document.addEventListener("online", checkConnection, false);
document.addEventListener("offline", checkConnection, false);
