Answer 1

deviceReady活动结束后你打电话给checkConnection 吗？

document.addEventListener("deviceready", onDeviceReady, false);

function onDeviceReady() {
    checkConnection();
}

在checkConnection中使用navigator.network.connection.type而不是navigator.connection.type因为https://issues.apache.org/jira/browse/CB-1807

Answer 2

这似乎是cordova 2.2.0中的一个错误
