The FullHTML plugin allows you to access the HTML code of an element, including the element itself. This plugin is read-only - you cannot set the full html of an object, only read it.
An example is, with the following code: <div id="myDiv"><b>some</b><i>text</i></div>
<div id="myDiv"><b>some</b><i>text</i></div>
Using the built-in html() you would be presented with: <b>some</b><i>text</i>
<b>some</b><i>text</i>
With this plugin, fullhtml() you would be presented with: <div id="myDiv"><b>some</b><i>text</i></div>
