jquery - Javascript works before turned into a wordpress template -

so tested theme static html/css/js before turning wordpress theme , worked perfectly. it's on wordpress it's throwing error in js file (line 593):

uncaught typeerror: cannot set property 'mynode' of undefined

directly after line

//add data mindmap var root = $('body>ul>li').get(0).mynode = $('body').addrootnode($('body>ul>li>a').text(), { 

here full js. haven't changed since uploading , making theme wordpress.

it came here: https://github.com/kennethkufluk/js-mindmap

any ideas? new js/jquery still :) thanks!!!
