Today there is a feature in the system that requires you to click a button to remove the check box in front of the tree node and make it unselected. I searched the Internet for a long time, and then I checked the API by myself. Finally I found a solution.
This is handled differently in extjs3.x and 4.x versions. In the 3.x version, you can do this:
This cancels the check state of the node and removes the check from the page.
The method in ExtJs4 is as follows:
This also works!
Practice is the mother of true knowledge, encounter problems are not afraid of difficult, do not retreat, will always be solved.

node.attributes.checked=false;
node.getUI().toggleCheck(false);
This cancels the check state of the node and removes the check from the page.
The method in ExtJs4 is as follows:
node.raw.checked=false;
node.set("checked",false);
This also works!
