This is my EXTJS code:

Ext.onReady(fu开发者_开发知识库nction(){
var treeLoader=new Ext.tree.TreeLoader({
                dataUrl:'json.php'
                                      });
var rootNode=new Ext.tree.AsyncTreeNode({
             text:'Root'
                                       });
var tree=new Ext.tree.TreePanel({
         renderTo:'treecontainer',
         loader:treeLoader,
          root:rootNode
                               });
});

HTML code:

<html>
<head>
 <meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<title>Tree Formation </title>
<link rel=stylesheet" type="text/css" href="ext-all.css" />
<script src="ext-base.js"> </script>
<script src="ext-all.js"> </script>
</head>
<body>
<script src="tree.js"> </script>
<title id="title">Tree Formed</title>
</body>
<div id="treecontainer" style="height:300px;width:200px;">
</div>
<html>

Json.php:

 [
      {id:'1',text:'No Children',leaf:true},
      {id:'2'.text:'Has Children',
           children:[{
                       id:'3',
                       text:'Youngster',
                       leaf:true
                     }]
      }

After executing the above code,it's displaying with only 'Root' as done,rest not displaying.When i click on that 'Root' Error encountered as "ACCESS IS DENIED" at LINE 7,CHAR 20287 in ext-base.js.Can u tell me what it's ....? ]

Looks like you don't have the correct path to your Json.php file, or you don't have read access.
