I have a hosted web app for LG WebOS TV.  
I am using plain Javascript and JQuery and HTML5

The webostv.js version, I am referencing is webOSTVjs-1.2.7/webOSTV.js and webOSTVjs-1.2.7/webOSTV-dev.js

The jquery version  
1.10.2/jquery.min.js  
1.8.5/jquery-ui.min.js  
3.3.2/jquery-confirm.min.js

My app works on WebOS4.0 and above.

My app does not work on WebOS 3.5 and below
