I have question to EasyUI developers from the same area: Can we get possibility to use the same JSON data format for Tree as we use for TreeGrid?

Using 'loadFilter' function and you will be able to change any data to the standard data format for tree.

Here is the example shows how to use 'loadFilter' function. <ul class="easyui-tree" data-options="data:treedata,loadFilter:treeFilter"></ul>
var treedata = [ {"id":1,"name":"All Tasks","begin":"3/4/2010","end":"3/20/2010","progress":60,"iconCls":"icon-ok"}, {"id":2,"name":"Designing","begin":"3/4/2010","end":"3/10/2010","progress":100,"_parentId":1,"state":"closed"}, {"id":21,"name":"Database","persons":2,"begin":"3/4/2010","end":"3/6/2010","progress":100,"_parentId":2}, {"id":22,"name":"UML","persons":1,"begin":"3/7/2010","end":"3/8/2010","progress":100,"_parentId":2}, {"id":23,"name":"Export Document","persons":1,"begin":"3/9/2010","end":"3/10/2010","progress":100,"_parentId":2}, {"id":3,"name":"Coding","persons":2,"begin":"3/11/2010","end":"3/18/2010","progress":80}, {"id":4,"name":"Testing","persons":1,"begin":"3/19/2010","end":"3/20/2010","progress":20} ]; function treeFilter(rows){ for(var i=0; i<rows.length; i++){ rows[i]['text'] = rows[i]['name']; } var nodes = []; // get the top level nodes for(var i=0; i<rows.length; i++){ var row = rows[i]; if (!row._parentId){ nodes.push(row); rows.splice(i,1); i--; } } var toDo = []; for(var i=0; i<nodes.length; i++){ toDo.push(nodes[i]); } while(toDo.length){ var node = toDo.shift(); // the parent node // get the children nodes for(var i=0; i<rows.length; i++){ var row = rows[i]; if (row._parentId == node.id){ if (node.children){ node.children.push(row); } else { node.children = [row]; } toDo.push(row); rows.splice(i,1); i--; } } } return nodes; }

With 5 loop statements, the code performance will be reduced?
