Big update: In starting markup, pages should now be identified with the attribute data-role="page". This allows us to then add ui-page programatically, hiding all non-active pages, and apply ui-page-active to one page at a time to show it. mobile.js is updated to find pages by this attribute now, instead of ui-page class. fixes issue 32 2010-09-18 16:20:35 +00:00			`<div data-role="page">`
updated markup to use data-role attrs in place of classes for header/content/footer 2010-09-21 14:58:54 +00:00			`<div data-role="header">`
