Please pass the parent node element to the 'reload' method.

Code:

var p = ...  // get your parent node
$('#tt').tree('reload', p.target);  // reload the parent node

var selectedNode = $('#tree').tree('getSelected');
$('#tree').tree('update', {
   target: selectedNode.target,
   state: 'closed'

Please open this example http://www.jeasyui.com/tutorial/tree/tree2_demo.html and then run the code below in your browser's console.

Code:

$('#tt').tree('reload',$('#tt').tree('getRoot').target);

You will see the root node is reloaded successfully.

yes root node is reloaded but if you add new node to node 2 in this page and want to reload node 2 to show children it is not work
because state is open ;

Please notice that you are loading tree nodes from remote server. If you call 'append' method to append tree nodes. These appended nodes will not be saved to your server. You must do some saving action to let the server return the correct data back to the browser.

that is right
 i add node in remote server (ajax ) and want reload just this node to see children,i will not reload root node because
1)my tree have more than 200,000 record  and it is bad performance
2)it is not good   for user that add node to level 3 and root node refresh and user will again open root again open level 2 to see node that create from client

How do you add new nodes to the tree? In fact you can call 'append' method to append new nodes to a specified node and then post these added nodes to your server. At any time you also can call 'reload' method to refresh the children nodes of a parent node.

If your issue continues, please provide an example or a link page to demonstrate your issue.
