Question

I am using phonegap to develop one of my iPhone app. In the index.html page I am implementing a small javascript code just to check if the Internet is available or not inside the onBodyLoad() function as below:

function onBodyLoad() {                                       
    if (!navigator.onLine) {   
         alert('offline');     
    }

    document.addEventListener("deviceready",onDeviceReady,false);
    //alert("here!");   
}

This just work fine but I want to exit from the application when user taps the “Ok” button of that alert message.

I tried the add navigator.device.exitApp() after the alert but did not work.

How can I exit from the application after tapping the “OK” button from the alert message?

Thanks

Answer 1

navigator.device.exitApp() is not supported on iOS as Apple is pretty down on apps closing themselves.

It is possible I believe by setting the UIApplicationExitsOnSuspend boolean to YES in your applications info plist (in a PhoneGap application this is in Supporting Files -> -info.plist).
