Description

NOTE: You must load your lzx with the lzt=history wrapper HTML to use LzHistory.

The LzHistory service manages interaction with the browser history and back button. Save state as often as you like, and advance the history when a new 'page' of values is required.

 <form>
     <input type="button" value="0" onclick="lzSetCanvasAttribute('foo', 0)"/> 
     <input type="button" value="1" onclick="lzSetCanvasAttribute('foo', 1)"/> 
 </form>
