help running simple Ext JS example? - extjs

I downloaded Ext JS 4.0.2a and I'm trying to do the Ext JS tutorial. I go the "essentials" example working, so I'm pretty sure I'm set up right. I'm trying to do the grid example here ...
http://www.sencha.com/learn/legacy/Tutorial:Getting_Productive
... but I can't get the grid to display.
My ExtStart.html looks like this:
<html>
<head>
<title>Introduction to Ext 2.0: Starter Page</title>
<!-- Include Ext and app-specific scripts: -->
<script type="text/javascript" src="../adapter/ext/ext-base.js"></script>
<script type="text/javascript" src="../ext-all-debug.js"></script>
<script type="text/javascript" src="ExtStart.js"></script>
<!-- Include Ext stylesheets here: -->
<link rel="stylesheet" type="text/css" href="../resources/css/ext-all.css">
<link rel="stylesheet" type="text/css" href="ExtStart.css">
</head>
<body>
<div id="grid-example"></div>
</body>
</html>
and my ExtStart.js is exactly like on the tutorial site like this:
Ext.onReady(function() {
// sample static data for the store
var myData = [['Apple',29.89,0.24,0.81,'9/1 12:00am'],
['Ext',83.81,0.28,0.34,'9/12 12:00am'],
['Google',71.72,0.02,0.03,'10/1 12:00am'],
['Microsoft',52.55,0.01,0.02,'7/4 12:00am'],
['Yahoo!',29.01,0.42,1.47,'5/22 12:00am']
];
// create the data store
var ds = new Ext.data.ArrayStore({
fields: [
{name: 'company'},
{name: 'price', type: 'float'},
{name: 'change', type: 'float'},
{name: 'pctChange', type: 'float'},
{name: 'lastChange', type: 'date', dateFormat: 'n/j h:ia'}
]
});
// manually load local data
ds.loadData(myData);
// create the colum Manager
var colModel = new Ext.grid.ColumnModel([
{header: 'Company', width: 160, sortable: true, dataIndex: 'company'},
{header: 'Price', width: 75, sortable: true, dataIndex: 'price'},
{header: 'Change', width: 75, sortable: true, dataIndex: 'change'},
{header: '% Change', width: 75, sortable: true, dataIndex: 'pctChange'},
{header: 'Last Updated', width: 85, sortable: true,
renderer: Ext.util.Format.dateRenderer('m/d/Y'), dataIndex: 'lastChange'}
]);
// create the Grid
var grid = new Ext.grid.GridPanel({
store: ds,
colModel: colModel,
height: 300,
width: 600,
title: 'My First Grid'
});
// render the grid to the specified div in the page
grid.render('grid-example');
});
Any ideas what I could be doing wrong? Sadly stumped. :(

You are using ExtJS4 but are referring to a legacy documentation.
There have been quite a few changes to the components and how they need to be wired together between the version that document was written for and version 4 that you are using.
Here is the array grid (and other) example(s) for ExtJS 4. -
HTML
Javascript code
For example, you are using Ext.grid.GridPanel. This is no longer valid. (Use Ext.grid.Panel instead)

You're store array of data is double nested, instead it should be ['1','4']. So only the one option was showing. I made a fiddle to demonstrate the combobox working.

So, what have I done to your code?
Changed the page to use an HTML5 setup - is this necessary? I just threw it in there, you'll have to decide
The type of store you're using is really an array store, so I changed the type
I changed your use of 'new' to the create method, which is advised in Ext JS
I removed some properties you had in place to simplify the code- by all means add these back in now you have a working example
Crucially, you should ensure the data you are supplying matches the data you are interpreting, the record model you are using, and the grid columns you're feeding. To simplify things I removed your reader (not particularly necessary to define given such a simple setup) so you only have the fields specified on the store mapped to whichever columns you want in the grid.

ExtJS 4 and XSS in textfield

I did a little test regarding XSS attacks in ExtJS4. My HTML page looks like this:
<html>
<head>
<link rel="stylesheet" type="text/css" href="ext-all.css"/>
<script type="text/javascript" src="ext-all-dev.js"></script>
<script type="text/javascript" src="testExtXSS.js"></script>
</head>
<body>
<div id="myDiv"></div>
</body>
</html>
and testExtXSS.js looks like this:
Ext.onReady(function() {
var formPanel = Ext.create('Ext.form.Panel', {
frame: true,
title: 'Form Fields',
width: 340,
bodyPadding: 5,
fieldDefaults: {
labelAlign: 'left',
labelWidth: 90,
anchor: '100%'
},
items: [
{
xtype: 'textfield',
name: 'textfield1',
fieldLabel: '<script>alert(document.cookie)</script>Text field',
value: '<script>alert(document.cookie)</script>Text field'
}
]
});
formPanel.render('myDiv');
});
I expected the script tag in fieldLabel to be executed but it was not. When I looked at the HTML elements using Firebug and Chrome Developer Tools I could see the script element in the HTML tree.
Can anyone explain to me how ExtJS inserts this into the DOM and why it is not executed.
Thanks and best regards,
Ronald
This is because the ext template is injected using innerHTML, which is the fastest approach, but comes with a drawback that scripts don't get executed.
But you can just use update() method for Ext.dom.Element:
...
{
xtype: 'textfield',
name: 'textfield1',
fieldLabel: '<script>alert(1)</script>Text field',
value: 'some val',
listeners: {
render: function(cmp) {
cmp.getEl().update(cmp.getEl().dom.innerHTML, true);
}
}
}
...

ExtJS 4.1 Rowexpander and Grid. Expand the specified item.extjs grid Rowexpander

Good day!
Need help ExtJS 4.1
There is a ComboBox. There is a Grid. Grid plugged plug rowexpander.
ComboBox and Grid take data from one array.
The purpose of the script: after selecting an item in the ComboBox - open the corresponding rowexpander in the grid.
That is, The user selects in ComboBox «Alcoa Inc» and in the field of Grid row with the name of the company «Alcoa Inc» rowexplander is disclosed.
Problem: I can not turn to the records in the table and call the event expandbody / collapsebody
After selecting a ComboBox'e I get the id of the selected item, which corresponds to the id record in Grid, but also how to use it, what would appeal - I can not understand.
grid.getView (). getNode (0) - got so appeal, but it's not something that would help me.
PS So far, the variables are declared as window.grid and window.simpleCombo to simplify debugging
The script:
Ext.Loader.setConfig({
enabled: true

Tell me the solution, the second day of the "struggling against the wall."
[opt] specify pluginId instead of id
use getPlugin() or grid.plugins[0] and "native" .toggleRow()
plugins: [{
ptype: 'rowexpander',
pluginId: 'atata',
rowBodyTpl : [
'<p>Company: <b>{company}</b></p>',
'<p><b>$ {price}</b></p>'
]
}],
function open_some_plus(val) {
grid.getPlugin('atata').toggleRow(val)
}
This code works:
//val = 5 for example
var store = grid.getStore();
var expander = grid.plugins[0];
var page = grid.store.currentPage;
var record = store.getAt(val);
expander.toggleRow(val);

Ext JS Charts shows Y-axis label in wrong / reverse order

Below is the code corresponding to the screenshot that I added. If you refer to the data fields at the beginning of the code, you will see that the Labels on the Y-axis shows wrong.
and importing these libs, which is the same import in the sample chars that I found in this official chart preview link (the zip file is at the end of the article, and the bar chart in it is also wrong!!!):
<link rel="stylesheet" type="text/css" href="../../resources/css/ext.css" />
<script type="text/javascript" src="../../ext-core.js"></script>
<script type="text/javascript" src="../../ext-chart.js"></script>
<script type="text/javascript" src="Bar3.js"></script>
Then I imported the following libs (the same libs that they import in this sample):
<link rel="stylesheet" type="text/css" href="ext-all.css" />
<script type="text/javascript" src="ext-all.js"></script>
<script type="text/javascript" src="Bar3.js"></script>
I got the correct result.
Ext.onReady(function () {
var chart;
var store1 = new Ext.data.JsonStore({
fields:['name', 'data1'],
data: [
{name:'Jan', data1: 2000},{name:'Feb', data1: 1800},
{name:'Mar', data1: 1500},{name:'Apr', data1: 1000}
]});
chart = new Ext.chart.Chart({
renderTo: Ext.get('graphDiv'),

autoScroll: true,

});
});
A known bug of extjs 4.0.0! Just an upgrade to 4.1.x will solve the problem.
