Extjs changes the check status of the tree node and clicks the button to remove the check box_extjs

There is a place in today's system that requires a function to remove the checkbox in front of a tree node after clicking a button, leaving it unselected. After searching online for a long time, and then checking the API myself, I finally found a solution. I will post the method below.

The processing methods in Extjs 3.x and 4.x versions are different. In version 3.x, you can do this:

Copy code The code is as follows:

node.attributes.checked=false;
node.getUI().toggleCheck(false);

In this way, you can cancel the check status of the node and remove the check mark on the page. The method of

in ExtJs4 is as follows:

Copy the code The code is as follows:

node.raw.checked=false;
node.set("checked",false);

This can also achieve the same effect!

Practice brings true knowledge. If you encounter problems, don’t be afraid of difficulties or shrink back. You will always be able to solve them.
