Tree menu written in JavaScript

The tutorial of helping customer home (www.bkjia.com) suddenly burst into a whim today. It may be too long to write something with js. As a result, jsTree is coming out. He said that his Shanzhai is based on limited js levels and that he can write something that he can play with himself. It really needs to be used in projects, but also needs to be further processed and transformed. Let's talk about the Code:

<! DOCTYPE html PUBLIC "-// W3C // dtd xhtml 1.0 Transitional // EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> 





Tip: the code can be modified before running!

Only the most important display actions are designed, and style customization and loading are not performed. In the future, maybe I will extend the live rewrite.
