<script>
Ext.onReady(function()
{
Ext.MessageBox.alert("hello","Hello,easyjf open source");
});
</script>

</html>
进一步，我们可以在页面上显示一个窗口，代码如下：
<script>
Ext.onReady(function()
{
var win=new Ext.Window({title:"hello",width:300,height:200,html:'<h1>Hello,easyjf open source</h1>'});
win.show();
});
</script>
在浏览hello.html，即可得在屏幕上显示一个窗口，如图xxx所示。
