本文介绍如何使用 ExtJS 构建一个 AJAX 加载内容的窗口，并通过 JavaScript 对加载的内容进行操作，实现页面元素高亮效果。

<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
<title>Ext JS in Action Chapter 01 | Hello World Window</title>
<link rel="stylesheet" type="text/css" href="./ext3/resources/css/ext-all.css" />
<script type="text/javascript" src="./ext3/adapter/ext/ext-base.js"></script>
<script type="text/javascript" src="./ext3/ext-all-debug.js"></script>
<script type="text/javascript">
	Ext.BLANK_IMAGE_URL = './ext3/resources/images/default/s.gif'; 
</script>
<script type="text/javascript" src="./helloWorld.js"></script>
</head>
<body>

</html>

function buildWindow() {

	var win = new Ext.Window({
		id     : 'myWindow',
		title  : 'My first Ext JS Window',
		width  : 300,
		height : 150,
		layout : 'fit',
		autoLoad : {
			url     : 'sayHi.html',
			scripts : true
		}
	});
	win.show();
}

Ext.onReady(buildWindow);

<div id='fxDiv'>Hello from the <b>world</b> of AJAX!</div>
<script type='text/javascript'>

function highlightWindow() {
	var win   = Ext.getCmp('myWindow');
	var winBody = win.body;
	winBody.highlight();
}

highlightWindow.defer(1000);

</script>

scripts:true就是执行里面的JavaScript,highlightWindow.defer(1000);的意思就是延迟一秒钟调用highlightWindow函数
