title: How do I load an mbox content without inserting into the dom
body: <p>I'm trying to interface with Adobe Test &amp; Target because I want to load JSON rather than markup through my mbox. I want to load some mbox content into javascript and manually add it to the DOM. I have searched all over for full documentation of the mbox.js but I can't find anything other than the very basics. It describes how to use <code>mboxDefine()</code> and <code>mboxUpdate</code> to target a specific dom element. Is there a function that just returns the content?
