<meta charset="UTF-8">
<title>extjs example</title>
<script type="text/javascript" src="../js/ext/adapter/ext/ext-base.js"></script>
<script type="text/javascript" src="../js/ext/ext-all.js"></script>
<link rel="stylesheet" type="text/css" href = "../js/ext/resources/css/ext-all.css"/>

  html: '<div>这里是窗体内容</div>',
  resizable: true,
  modal: true,

  maximizable: true,
  minimizable: true
});
win.show();
});
</script>


2、表单(FormPanel)

<script type="text/javascript">
         Ext.onReady(function () {

             });
             var win = new Ext.Window({

                 modal: true,
                 closable: true,
                 maximizable: true,
                 minimizable: true,
                 items: form
