extjs面向对象设计
Ext.namespace('Ext.practise');
//给person类添加了name属性，并赋值
Ext.apply(Ext.practise.Person.prototype,{
name:'a'
});
//{}表示一个类
//[]表示一个数组//类的实例方法
Ext.apply(Ext.practise.Person.prototype,{
name:'a',
sex:'b',
print:function(){
alert(String.format("姓名:{0},性别:{1}",this.name,this.sex));
}
});
varperson=newExt.practise.Person();
person.name="a";
person.sex="b";
person.print();//类的静态方法
Ext.practise.Peron.print=function(_name,_sex){
varperson=newExt.practise.Peron();
person.name=_name;
person.sex=_sex;
person.print();
};//构造方法
Ext.practise.Peron=function(_cfg){
Ext.apply(this,_cfg);
};
Ext.practise.Peron=function(_name,_sex){
varperson=newExt.practise.Peron({name:_name,sex:_sex});
person.print();
};
Ext.apply(Ext.practise.Peron.prototype,{
print:function(){
alert(String.format("姓名:{0},性别:{1}",this.name,this.sex));
}
});var p = new Ext.practise.Peron({name : "a",sex:"b"});p.print();
//类继承
Ext.practise.Peron=function(_cfg){//_cfg父类
Ext.apply(this,_cfg);
};
Ext.apply(Ext.practise.Peron.prototype,{
job:"worker",
print:function(){
alert("name:{0},sex:{1},job:{2}",this.name,this.sex,this.job);
}
});Ext.practise.man = function(_cfg){//子类
Ext.apply(this,_cfg);
};Ext.extend(Ext.practise.man,Ext.practise.Peron,{job:"teacher"});
//类重写
Ext.extend(Ext.practise.man,Ext.practise.Peron,{
