用html很好实现的功能，却在extjs中，如此蛋疼。。。

废话不说，先上代码：

 <form id="form_tKEim7ks" title="修改登录ID" bodyStyle="padding:5px 5px 0" url="editLogonId.dt" hidden="'$!{type}'!='logon'">
  <items>
	<container id="container_aj8Htzdm" layout="hbox" margin="5">

			beforerender:function(me,opt){
				Ext.apply(Ext.form.field.VTypes, {
					mobile: function (val, field) {
						var mobile=  /^[0-9]{11}$/;
						return mobile.test(val);
					},
					mobileText: '非法手机号码'
				});
			}
		  }]]></listeners>

					  change:function(me,newv,oldv,opt){

						items.each(function(item,index,length){

实现功能如下图：
所有这一切都是纠结的radiogroup惹得祸
