jquery mobile backbutton to quit App for specific Page


Tag: cordova,jquery-mobile

I had a look around and can't seem bind the backbutton to a specific page for Android phone in Phonegap/JQM.

I am trying to only allow the backbutton to trigger navigation.notification.confirm to prompt the logout at 1 specific page. But it either doesnt prompt it or prompt it every single page.

This below doesn't trigger

$(document).on( 'pageinit','homepage',function onLoad(){
                document.addEventListener('deviceready', deviceReady, false);
        function deviceReady() {
            document.addEventListener('backbutton', backButtonCallback, false);

        function backButtonCallback() {
            navigator.notification.confirm('Do you want to exit the app? If not, use the top left button to go to Previous Page',confirmCallback);
        function confirmCallback(buttonIndex) {
            if(buttonIndex == 1) {
            return true;
        else {
            return false;

This doesn't trigger either

function onLoad(){
                document.addEventListener('deviceready', deviceReady, false);
        function deviceReady() {
            document.addEventListener('backbutton','#homepage' backButtonCallback, false);

        function backButtonCallback() {
            navigator.notification.confirm('Do you want to exit the app? If not, use the top left button to go to Previous Page',confirmCallback);
        function confirmCallback(buttonIndex) {
            if(buttonIndex == 1) {
            return true;
        else {
            return false;


If you are using Jquery Mobile 1.4.5 getActivePage() can be handy. $.mobile.activePage was deprecated in JQM 1.4.0 (see Changes since 1.4.0 beta #deprecation).

//handle Back button
function onDeviceReady() {
    // Register the event listener
    document.addEventListener("backbutton", onBackKeyDown, false);
    console.log('Device ready - register onBackKeyDown()');                

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

function onBackKeyDown() {
    var active_page = $( ":mobile-pagecontainer" ).pagecontainer( "getActivePage" );
    var id'id');
    if (id==='homepage') {
        if (confirm('Do you want to exit the app? If not, use the top left button to go to Previous Page?')==true){

This code will exit app only if activePage id is homepage.

Tell me if code works for you.
