JS模式：又一个简单的工厂模式
运行下面代码
<!DOCTYPE html>
<html>
<head>
<title></title>
</head>
<body>
<script>
function Car(options){
this.doors = options.doors || 4;
this.state = options.state || "brand new";
this.color = options.color || "silver";
};
function Truck(options){
this.state = options.state || "used";
this.wheelSize = options.wheelSize || "large";
this.color = options.color || "blue";
};
function VehicleFactory(){};
VehicleFactory.prototype.vehicleClass = Car;
VehicleFactory.prototype.createVehicle = function( options ){
if(options.vehicleType == "car"){
this.vehicleClass = Car;
}else{
this.vehicleClass = Truck;
};
return new this.createVehicle(options);
};
var carFactory = new VehicleFactory({
vehicleType : 'truck',
state : 'like new',
color : 'red',
wheelSize : 'small'
});
console.log( carFactory instanceof VehicleFactory);
console.log( carFactory );
function TruckFactory(){};
TruckFactory.prototype = new VehicleFactory();
TruckFactory.prototype.vehicleClass = 'truck';
var truckFactory = new TruckFactory();
console.log( truckFactory instanceof TruckFactory);
//抽象 工厂模式---->_->
var AbstractVehicleFactory = (function(){
//定义车辆的类型，用来存储数据
var types = {};
return {
registerVehicle : function(type,vehicle){
types[type] = vehicle;
},
getVehicle : function(type,customizatoins){
var vehicle = types[type];
return (vehicle) ? new topics[type](customizations) : null;
}
}
})();
</script>
</body>
