4. 支持类静态方法
添加类Person4.js 代码如下：
Ext.namespace("Ext.china_hongzk");
Ext.china_hongzk.Person = Ext.emptyFn; // Ext.emptyFn 等同于function(){};
Ext.china_hongzk.Person.print = function(_name,_sex){ //定义print类静态方法
var _person = new Ext. china_hongzk.Person();
_person.name = _name;
_person.sex = _sex;
_person.print(); //print类实例方法
}
Ext.apply(Ext.china_hongzk.Person.prototype,{
name: "",
sex: "",
print:function(){
alert(String.format("xingming:{0},xingbie:{1}",this.name,this.sex));
}
});
