复制代码 代码如下:
var orchard = function (){ //基类型构造函数代理 静态方法都在代理函数上
this.constructor && this.constructor.apply(this,arguments);
};
orchard.extend = function() {
var parentobj = this;
var parameters = parentobj.parameters ?
parentobj.parameters.concat(_.toarray(arguments)) : _.toarray(arguments);
var thisobj = function(){ //继承类型构造函数代理
var newparameters = parameters.concat(_.toarray(arguments));
this.constructor && this.constructor.apply(this,newparameters);
};
_.extend(thisobj,parentobj);
_.extend(thisobj.prototype,parentobj.prototype);
thisobj.parameters = parameters;
thisobj.base = thisobj.prototype.base = parentobj; //基类型的代理函数
thisobj.supper = thisobj.prototype.supper = parentobj.prototype; //基类型的构造函数 类成员都在构造函数上
return thisobj;
};
orchard.define = function(object){
if(typeof object === undefined) object = {constructor: function(){}};
this.prototype = object.constructor;
this.prototype.constructor = this.prototype;
for(var name in this.base)
if(typeof this[name] === undefined)
this[name] = this.base[name];
for(var name in this.supper)
if(typeof this.prototype[name] === undefined)
this.prototype[name] = this.supper[name];
for(var i = 0; i _.extend(this.prototype,arguments[i]);
this.prototype.base = this.base;
this.prototype.supper = this.supper;
this.supper = undefined;
delete this.supper;
return this;
};
orchard.definenew = function(){
var newclass = this.extend();
return define.apply(newclass,arguments);
};
调用：
复制代码 代码如下:
var person = orchard.definenew({
constructor: function(name){
this.name = name;
},
say: function(){ return hello, i'm + name;}
});
var aben = person.extend(aben);
aben.define({
constructor: function(){
this.supper.apply(this,arguments);
}
});
var aben = new aben();
alert(aben.say());
思路就是这样的，代码没验证过。分享的思路，大家自己看着办。哈哈~~
