Question

I have a phonegap app that requires I capture the back button. This works swimmingly but when I am at the main screen and the back button is pressed I want to call the original event handler and let the app close or do whatever comes naturally to the platform with such a press. I know I can tell the app to quit but understand this is bad form for iPhone apps.

No matter what I try (and I have tried many things) I cannot get the original handler to fire. Any advice?

In my code I have a switch statement inside my backbutton event handler that directs the app as needed to the effect of:

switch blahBlah
{
    case 'this' :
        doThis() ;
        break;
    case 'main' :
        // What do I do here that is well behaved for all platforms??? 
        break;
    default:
        doFoo() ;
} 

Answer 1

Detect whenever you land on the main screen and remove your custom event handler.

document.removeEventListener( "backbutton", function(){}, false );

and add the event listener on the other pages (or sections).

document.addEventListener( "backbutton", OverrideBackButton, false );

Hope that helps.
