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?

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'; //开发者_如何学Godoesn't work
});
new Ext.Panel({
id: 'panel1',
renderTo: 'content',
width: '210px',
title: 'Extended Info',
html: 'original text',
collapsible: true
});
});
</script>
</head>
<body>
<button id="buttonInfo">
Show Info
</button>
<div id="infoBox">
</div>
<div id="content-wrapper">
<div id="content"></div>
</div>
</body

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();
加载中,请稍侯......
