Answer 1

您是否在deviceReady事件发生后打电话给CheckConnection？

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

在checkConnection中，只需使用 navigator.network.connection.type而不是navigator.connection.type，因为https://issues.apache.org/jira/jira/browse/cb-1807
