How can I manipulate contents of an extjs panel as I can a DOM element?

In the following extJS page, when I click the button, the content of the HTML Div "buttonInfo" changes correctly.

I want to also change the contents of the panel that I created with extJS.

However, when I change the contents of the panel as I do the div, the whole panel is simply replaced.

How can I change the contents of my panel object from within my button's click handler?

before:

alt text

after:

alt text

<!DOCTYPE html>
<html>
    <head>
        <meta http-equiv="Content-Type" content="text/html; charset=utf-8">
        <link rel="stylesheet" type="text/css" href="ext/resources/css/ext-all.css">
        <style type="text/css">
            body {
                padding: 20px;
            }
            div#infoBox {
                margin: 10px 0 0 0;
                width: 190px;
                height: 100px;
                background-color: lightblue;
                padding: 10px;
            }
            div#content {
                margin: 10px 0 0 0;
            }
            div.x-panel-body {
                padding: 10px;

            Ext.onReady(function(){

                Ext.get('buttonInfo').on('click', function(){
                    Ext.get('infoBox').update('This is the <b>new</b> content.');
                    Ext.get('panel1').update('new info');
                    //Ext.get('panel1').html = 'new info111'; //doesn't work
                    //panel1.html = 'new info222'; //doesn't work
                });

                new Ext.Panel({
                    id: 'panel1',
                    renderTo: 'content',
                    width: '210px',
                    title: 'Extended Info',
                    html: 'original text',
                    collapsible: true
                });

            });

Ext.get gives you the dom object, use Ext.getCmp instead so that it returns the Ext object back, then you can use the update method on the panel:

Try:

Ext.getCmp('panel1').update('new info');

Hope it helps.

Try:

var Data = 'new info'; panel1.overwrite(panel1.body, Data); panel1.doComponentLayout();
