Modify the automatic selection of child nodes for the parent node of the mztreeview authorization Node

A previous project used mztreeview when authorizing the user node. Recently, some colleagues told me that the information displayed when modifying the user permission is always incorrect, this is because he only wants to grant some permissions to a certain node of a person, but he always selects all permissions. It should be true if he has something. As soon as the parent node is selected, all child nodes are automatically selected. Looking at JS CodeThen, I found row 312 under system/web/UI/webcontrols/mztreeview. JS:

Set: Node. Checked = Node. parentnode. Checked | Node. checked;

Changed:Node. Checked=Node. checked;

Solve the problem.
