One, the reason for expansion

Ztree uses a flat method of data loading, that is, the ID (self-ID), PID (parent ID) way, referring to http://www.ztree.me/v3/demo.php#_102, so the extension Easyui tree also use this way of the people;

Ii. Basic Methods

1, Loading extension files

2, instantiate the tree in JS

Third, the specific method (easyui1.4.1 test is available)

1, Load Extension JS

2, instantiation

JSON file:
