Data/Parameters manipulation between page transitions
It is possible to send a parameter/s from one page to another during page transition. It can be done in few ways.

Solution 1:
You can pass values with changePage:
$.mobile.changePage('page2.html', { dataUrl : "page2.html?paremeter=123", data : { 'paremeter' : '123' }, reloadPage : true, changeHash : true });
And read them like this:
$(document).on('pagebeforeshow', "#index", function (event, data) {
var parameters = $(this).data("url").split("?")[1];;
parameter = parameters.replace("parameter=","");
alert(parameter);
});

index.html
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8" />
<meta name="viewport" content="widdiv=device-widdiv, initial-scale=1.0, maximum-scale=1.0, user-scalable=no" />
<meta name="apple-mobile-web-app-capable" content="yes" />
<meta name="apple-mobile-web-app-status-bar-style" content="black" />
<title>

$(document).on('pagebeforeshow', "#index",function () {
$(document).on('click', "#changePage",function () {
$.mobile.changePage('second.html', { dataUrl : "second.html?paremeter=123", data : { 'paremeter' : '123' }, reloadPage : false, changeHash : true });
});
});
$(document).on('pagebeforeshow', "#second",function () {
var parameters = $(this).data("url").split("?")[1];;
parameter = parameters.replace("parameter=","");
alert(parameter);
});

Solution 2:
Or you can create a persistent javascript object for a storage purpose. As long ajax is used for page loading (and page is not reloaded in any way) that object will stay active.
var storeObject = {
firstname : '',
lastname : ''
}

Solution 3:
You can also access data from the previous page like this:
$('#index').live('pagebeforeshow', function (e, data) {
alert(data.prevPage.attr('id'));
});
prevPage object holds a complete previous page.
Solution 4:
As a last solution we have a nifty HTML implementation of localStorage. It only works with HTML5 browsers (including Android and iOS browsers) but all stored data is persistent through page refresh.
if(typeof(Storage)!=="undefined") {
localStorage.firstname="Dragan";
localStorage.lastname="Gaic";
}
