新件一个JS文件

 

// JavaScript Document
Ext.namespace('CRM.Panels');
CRM.Panels.UserDetail = Ext.extend(Ext.Panel,{
     width:350,
  height:120,
  data:{
       ID: 0,
    FirstName: '',
    LastName: '',
    Email: '',
    City: '',
    Phone:''
  },
  split:true,
  tpl: new Ext.XTemplate([
    '<div>编号:{ID}</div>',
       '<div>姓名:{FirstName}-{LastName}</div>',
    '<div>电话:{Phone}</div>',
    '<div>城市:{City}</div>',
    '<div>邮箱:{Email}</div>'
  ]),
  initComponent:function(){
        CRM.Panels.UserDetail.superclass.initComponent.call(this);
    if(typeof this.tpl === 'string'){
        this.tpl = new Ext.XTemplate(this.tpl); 
    }
    this.addEvents('UAlert');//注册新事件
    this.addListener({//侦听函数 www.2cto.com
         UAlert: { //注册的新事件
       fn:this.onAlert,//调用onAlert方法
       scope: this
      }  
    });
  },
  //////////////
  onAlert: function(){
    alert('注册的新事件');
  },
  UAlert:function(){
    this.fireEvent('UAlert');
  },
  /////////////////////
  onRender: function(ct, position){
          CRM.Panels.UserDetail.superclass.onRender.call(this, ct, position);
    if(this.data){
        this.update(this.data);
    }
  },
  update: function(data){
   this.data = data;
   this.tpl.overwrite(this.body, this.data);
  // this.fireEvent('update',this.data);
  }
});

//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],
    title:'User Detail'
    }   
]*/

 

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>
<button id="alert">注册的新事件</button>
