本文實例講述了js簡單工廠模式用法。分享給大家供大家參考。具體實現方法如下：
<!DOCTYPE html><html><head><title>簡單工廠模式</title></head><body><script> //簡單工廠模式 var BicycleShop = function(){}; BicycleShop.prototype ={ sellBicycle : function(model){ var bicycle = null; switch(model){ case 'The Speedster': bicycle = new Speedster(); break; case 'The lowride': bicycle = new Lowride(); break; case 'The Comfort Cruise': bicycle = new ComfortCruise(); break; }; Interface.ensureImplements(bicycle,Bicycle); bicycle.assemble(); bicycle.wash(); return bicycle; } }; var AcmeBicycleShop = function(){}; extent(AcmeBicycleShop, BicycleShop); AcmeBicycleShop.prototype.createBicycle = function(model){ var bicycle = null; switch(model){ case 'The speedster': bicycle = new AcmeSpeedster(); break; case 'The Lowrider': bicycle = new AcmeLowrider(); break; case 'The Flatlander': bicycle = new AcmeFlatlander(); break; case 'The Comfort Cruiser': default : bicycle = new AcmeComfortCruiser(); }; Interface.ensureImplements(bicycle,Bicycle); return bicycle; }; //工廠模式適用與一個 fn 根據參數不同，創建不同的對象</script></body></html>希望本文所述對大家的javascript程序設計有所幫助。
