    Lightbulb Detecting iPhone buttons

    I want to build small real-time application in Sencha Touch 2 for iPhone 4S. I need to build a timer in JavaScript which has to be displayed on all pages. My question is: is it possible for Sencha Touch 2 to detect events coming from pressed iPhone buttons? I would like to detect when iPhone lost focus in my application, so I could send some data to the server before it has happened.


    I would like to detect when iPhone is closing the application (pressing home button) or when I am pressing the upper button (iPhone goes to locked screen mode). I doubt if it is possible to detect in JavaScript, but maybe is there any work around?

    Default

    The browser doesn't expose any events when this happens AFAIK
