treegrid example doesn't work
I'm trying to run the treegrid example but it only gives me the grid with no data in it!
this is my default.aspx:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>My tree grid</title>
<!-- Ext -->
<link rel="stylesheet" typ开发者_StackOverflow中文版e="text/css" href="ExtJs4/resources/css/ext-all.css" />
<script type="text/javascript" src="ExtJs4/bootstrap.js"></script>
<script type="text/javascript" src="ExtJs4/ext-all.js"></script>
<!-- example code -->
<script type="text/javascript" src="Scripts/treepanel.js"></script>
</head>
<body>
<h1>My tree grid</h1>
<div id="tree-div"> </div>
this is my treepanel.js
Ext.Loader.setConfig({ enabled: true }); //
Ext.Loader.setPath('Ext.ux', '../ux');
Ext.require([
'Ext.tip.QuickTipManager',
'Ext.container.Viewport',
'Ext.layout.*',
'Ext.form.Panel',
'Ext.form.Label',
'Ext.grid.*',
'Ext.data.*',
'Ext.tree.*',
'Ext.selection.*',
'Ext.tab.Panel'
]);
Ext.onReady(function ()
{
Ext.define('Task', {
extend: 'Ext.data.Model',
fields: [
{name: 'task', type: 'string'},
{name: 'user', type: 'string'},
{name: 'duration', type: 'string'}
]
});
var store = Ext.create('Ext.data.TreeStore', {
model: 'Task',
proxy: {
type: 'ajax',
url: 'treegrid.json'////
},
folderSort: true
});
//Ext.ux.tree.TreeGrid is no longer a Ux. You can simply use a tree.TreePanel
var tree = Ext.create('Ext.tree.Panel', {
title: 'Core Team Projects',
width: 500,
height: 300,
renderTo: 'tree-div',
rootVisible:true,
store: store,
autoload:true,
columns: [{xtype: 'treecolumn', text: 'Task', dataIndex: 'task' },{text: 'Assigned To', dataIndex: 'user'}]
});
});
am I doing something wrong here? I have no error msg from my firebug...so why isn't it working?
if I can't run an example how am I going to do more..I'm frustrated with this.
not sure, but the "autoLoad: true" is now on the panel, but shouldn't it be on the store?
Install PHP and do the following in IIS:
- click on the new site
- click on MIME types
- right click in open space > Add > File name extension: "json" ... MIME Type: "application/x-javascript"
