新件一个JS文件

// JavaScript Document
Ext.namespace('CRM.Panels');
CRM.Panels.UserDetail = Ext.extend(Ext.Panel,{
     350,
  height:120,

//把新建的自定义组件注册为一种xtype
Ext.reg('UserDetail',CRM.Panels.UserDetail);
/*使用：
items:[

    region:'west',
    xtype:'UserDetail',
    data: userData[0],

    }   
]*/

在页面上：

<script language="javascript">
 var userData = [
    {ID:1,FirstName:'Zhang',LastName:'Jinshan',Email:'zjs@qq.com',Phone:'123456',City:'ZhangPing'},
    {ID:2,FirstName:'Wang',LastName:'wu',Email:'wjf@qq.com',Phone:'123456',City:'ZhangPing'}
 ];
 Ext.onReady(function(){
  var userDetail = new CRM.Panels.UserDetail({
      applyTo:'body',
   title:'User Detail',
   data:userData[0]
  });
    updateContact = function(event, el, data){
         userDetail.update(data.data);//调用更新数据
  }
  Ext.get('xt').on('click',updateContact,this,{data:userData[1]});
  Ext.get('alert').on('click',function(){
            userDetail.UAlert();
            });
 })
</script>

<button id="xt">点击</button>
