How to change page in jQuery mobile (1.4 beta)?

Question

As of jQuery Mobile 1.4, $.mobile.changePage() is deprecated and replaced with:

$(":mobile-pagecontainer").pagecontainer("change", "target", { options });

Shortened…

$.mobile.pageContainer.pagecontainer("change", "target", { options });

Even shorter…⁽¹⁾

$("body").pagecontainer("change", "target", { options });

Note: target is #page_id or URL.

Demo

⁽¹⁾ <body> is pageContainer by default, unless $.mobile.pageContainer is modified on mobileinit.
