javascript - jQuery Mobile - Android Back button prompt confirmation -

i have jquery mobile app (about 7 html pages). want change button functionality in android (using eclipse phonegap). tried @overwrride won't work properly.

i on every page, when button hit, prompt: "are sure want exit?" yes , no options.

now have script exits app completely.

<script type="text/javascript">   document.addeventlistener("deviceready", ondeviceready, false);   function ondeviceready() {     document.addeventlistener("backbutton", onbackkeydown, false);   }   function onbackkeydown() {     navigator.app.exitapp();   } </script> 

is there way have inside function onbackkeydown() jquery window popup , have if condition, click yes execute navigator.app.exitapp(); or cancel if hit no?

i new this, appreciate help!

thanks.

if understand question right, :

document.addeventlistener("deviceready", ondeviceready, false); function ondeviceready() {       document.addeventlistener("backbutton", onbackkeydown, false); //listen user clicking on button }  function onbackkeydown(e) {     e.preventdefault();     navigator.notification.confirm("are sure want exit ?", onconfirm, "confirmation", "yes,no"); // prompt user choice }  function onconfirm(button) {       if(button==2){ //if user selected no, nothing         return;     }else{         navigator.app.exitapp(); // otherwise quit app.     } }
