Windows Phone PhoneGap app back button issue

Question

I am developing Windows Phone PhoneGap app. When clicking hardware back button, It is going to the previous page using history.go(-1); But when I am in initial page and click the back button It is navigating to the same page instead of killing the application. Any help is appreciated.

Answer 1

To configure back button you can use these functions:

// for exit app
navigator.app.exitApp();

// for back hsitory use
navigator.app.backHistory()

complete code :

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

function onDeviceReady(){
    document.addEventListener("backbutton", function(e){
       if($.mobile.activePage.is('#home')){
           e.preventDefault();
           navigator.app.exitApp();
       }
       else {
           navigator.app.backHistory()
       }
    }, false);
}
