If you prefer, you can tell jQuery Mobile to keep previously-visited pages in the DOM instead of removing them. 

1. $.mobile.page.prototype.options.domCache = true;

1. <div data-role="page" id="cacheMe" data-dom-cache="true">

1. pageContainerElement.page({ domCache: true });

1.             // Prevent pages from being cached
               $( document ).on("mobileinit", function(){
                   $( document ).on('pagehide', 'div[data-role="page"]',
                   function (event, ui) {
                           $(event.currentTarget).remove();
                   });
               });
