Same code works fine with iOS 10.3.3 on iPhone 5C, so I doubt the issue is with
the code.
Nevertheless the test I use is:
{code:javascript}
if ((window.device && window.device.platform === 'browser' &&
!window.navigator.onLine) || ('Connection' in window &&
window.navigator.connection.type === window.Connection.NONE)) {
// query data from IndexedDB
window.alert('offline');
} else {
// query data from Restful API with $.ajax and cache relevant data in
IndexedDB
window.alert('online');
}
{code}
Note that with 3G but without Wifi:
{code:javascript}
window.alert(
'platform: ' + window.device.platform +
'\nonLine: ' + window.navigator.onLine +
'\ntype: ' + window.navigator.connection.type +
// Note: there used to be window.navigator.network.isReachable function -
@see
https://www.neotericdesign.com/articles/2011/3/checking-the-online-status-with-phonegap-jquery
// '\nreachable: ' + ($.isFunction(window.navigator.network.isReachable) ?
window.navigator.network.isReachable() : 'N/A') +
// '\neffective: ' + window.navigator.connection.effectiveType +
'\nOffline test: ' + (('Connection' in window &&
window.navigator.connection.type === window.Connection.NONE) || (window.device
&& window.device.platform === 'browser' && !window.navigator.onLine))
);
{code}

> When an iPhone (SE) with iOS 11.2 is disconnected from WIFI *+but connected
> to a CELL network+* (Vodafone UK) either;
> * by being out of reach of a WIFI network, or
> * by forgetting the WIFI network in iOS settings or
> * by disabling WIFI in the iOS control panel:

> # A cordova/phonegap app reports navigator.connection.type ===
> Connection.NONE instead of Connection.CELLxxx
> # Upon launching such cordova/phonegap app an offline event is triggered
>
