Caching pages in the DOM
\nTo keep all previously-visited pages in the DOM, set the domCache option on the page plugin to true, like this:
\n$.mobile.page.prototype.options.domCache = true;
\nAlternatively, to cache just a particular page, you can add the data-dom-cache=”true” attribute to the page’s container:
\n<div data-role=”page” id=”cacheMe” data-dom-cache=”true”>
\nYou can also cache a page programmatically like this:
\npageContainerElement.page({ domCache: true });
\nThe drawback of DOM caching is that the DOM can get very large, resulting in slowdowns and memory issues on some devices. If you enable DOM caching, take care to manage the DOM yourself and test thoroughly on a range of devices.<\/p>\n
