Extjs自定义组件
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.zzzyk.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>
