Person类是父类：
1 Ext.namespace("Ext.dojochina");
2 //EXT的构造方法
3 Ext.dojochina.Person = function(_cfg) {
4 Ext.apply(this, _cfg);
5 };
6
7 //实例方法
8 Ext.apply(Ext.dojochina.Person.prototype, {
9 job:"无",
10 print:function(){
11 alert(String.format("姓名:{0}, 性别:{1},角色:{2}", this.name, this.sex, this.job));
12 }
13 });
Student类是继承自Person类的，只是job=Student
1 Ext.namespace("Ext.dojochina");
2 //构造函数
3 Ext.dojochina.Student = function(_cfg) {
4 Ext.apply(this, _cfg);
5 };
6 //继承的写法
7 Ext.extend(Ext.dojochina.Student,Ext.dojochina.Person,{
8 job:"学生"
9 });
