The event fires when the user presses the back button.
document.addEventListener("backbutton", yourCallbackFunction, false);
To override the default back-button behavior, register an event listener for the backbutton
event, typically by calling document.addEventListener
once you receive the deviceready
event. It is no longer necessary to call any other method to override the back-button behavior.
document.addEventListener("backbutton", onBackKeyDown, false); function onBackKeyDown() { // Handle the back button }
