5. 支持构造方法
添加类Person5.js 代码如下：
Ext.namespace("Ext.china_hongzk");
Ext.china_hongzk.Person = function(_cfg){
Ext.apply(this,_cfg);
};
Ext.china_hongzk.Person.print = function(_name,_sex){
var _person = new Ext.china_hongzk.Person({name:_name,sex:_sex});
_person.print();
}
Ext.apply(Ext.china_hongzk.Person.prototype,{
print:function(){
alert(String.format("xingming:{0},xingbie:{1}",this.name,this.sex));
}
});<html xmlns="http://www.w3.org/1999/xhtml" >
