jsonengineとExt.treeを使ったデモ

デモはこちら。http://uchjava.appspot.com/samples/extjs/samples/tree.html




コードはこんな感じ。

Ext.onReady(function() { 
 
 var treePanel = new Ext.tree.TreePanel( { 
  dataUrl      : '/_je/testTree',
  requestMethod: 'GET',
  nodeParameter: null,
  root: { 
   nodeType: 'async',
   text    : '/',
   id      : 'xxx' 
  } 
 });
 
 // event override 
 treePanel.on("beforeload", function(node){ 
  this.loader.baseParams.cond = 'node.eq.' + node.id;
 });
 
 // render the tree 
 treePanel.render(Ext.getBody());
 treePanel.getRootNode().expand();
 
});
