javascript设计模式 – 原型模式原理与应用实例分

var Dialog = function(){
 this.init = function(arg){
 this.element = arg.element;
 this.name = arg.name;
 }
 this.show = function(){
 console.log(this.name + ' is show -> ' + this.element);
 }
};
var createDialog = function(arg){
 var _dialog = function(){};
 _dialog.prototype = new Dialog();
 
 var resDia = new _dialog();
 resDia.init(arg);
 return resDia;
 
}
var notice = createDialog({name:'notice',element:'<div>notice</div>'});
var toast = createDialog({name:'toast',element:'<div>toast</div>'});
var warnin = createDialog({name:'warnin',element:'<div>warnin</div>'});
 
notice.show(); //notice is show -> <div>notice</div>
toast.show(); //toast is show -> <div>toast</div>
warnin.show(); //warnin is show -> <div>warnin</div>
