<link  rel="stylesheet" href="theme-graphite-all.css">
<script src="ext-all.js"></script>   
<script>Ext.onReady(function () { /*---------------------------------------------------------------------------------*/

     Ext.create('Ext.panel.Panel', {  /*--创建，等于var aPanel = new Ext.panel.Panel({ */
            renderTo: 'helloWorldPanel',
            height: 200,
             600,
            title: 'Hello world',
            html: 'First Ext JS Hello World Program'
      });

}); </script><!------------------------------------------------------------------------------------------------------->

<div id="helloWorldPanel" />  <!--调用-->

     Ext.create('Ext.Panel', {     //定义
          renderTo: Ext.getBody(),
            height: 200,
             600,
            title: 'Hello world',
            html: 'First Ext JS Hello World Program'
      });

这个只能window类才特有

Ext.create('Ext.window.Window', {
    title: 'Hello',
    height: 200,
     400,
    layout: 'fit',
    items: {  // Let's put an empty grid in just to illustrate fit layout
        xtype: 'grid',
        border: false,
        columns: [{header: 'World'}],                 // One header just for show. There's no data,
        store: Ext.create('Ext.data.ArrayStore', {}) // A dummy empty data store
    }
}).show();

<link  rel="stylesheet" href="theme-graphite-all.css">
<script src="ext-all.js"></script>   
<script>
         Ext.onReady(function() {

Ext.create('Ext.Button', {
    text: 'Click me点我呀',
   renderTo: 'aButton',
    handler: function() {
        alert('You clicked the button!');
    }
});

         });
</script>

 <body>
         <div id="aButton" />
