var __fns = {};function define(name,fn){	__fns[name] = fn;}function require(names,callback){	var fns = [];	$(names).each(function(i,name){		fns.push(__fns[name]);	});	callback.apply(window,fns);}

    需要留意的是，在使用的时候，require当中的参数是函数，也就是说可以进行new操作的，而不是已经new过后的实例。

    示例用法：

//预约时间	function ServiceOrderTime(orderTime){		this.userAddress = orderTime.userAddress;//小区街道		this.userAddressNo = orderTime.userAddressNo;//楼宇门派号		this.lngLatPoi = orderTime.lngLatPoi;		this.scheduleTime = orderTime.scheduleTime;		this.serviceIntention = orderTime.serviceIntention;		this.orderDay = new OrderDay();		this.orderDay.fromTimelong(this.scheduleTime);		this.orderTime = new OrderTime();		this.orderTime.fromTimelong(this.scheduleTime);	}	ServiceOrderTime.prototype.toJson = function(){		return {			userAddress : this.userAddress,			userAddressNo : this.userAddressNo,			lngLatPoi : this.lngLatPoi,			scheduleTime : this.scheduleTime,			serviceIntention : this.serviceIntention,			travelToNewCost : this.travelToNewCost		};	}	ServiceOrderTime.prototype.stringify = function(){		return this.lngLatPoi + '-' + this.scheduleTime + '-' + this.serviceIntention;	}	ServiceOrderTime.prototype.eq = function(other){		if ( other ) { 			return this.lngLatPoi == other.lngLatPoi && this.scheduleTime == other.scheduleTime && this.serviceIntention == other.serviceIntention; 		}		return false;	}	ServiceOrderTime.prototype.travelCost = function(lnglatPoi,callback){		var me = this;		getTimeCost(this.lngLatPoi,lnglatPoi,function(mins){			me.travelToNewCost = mins;			callback(mins);		});	}	ServiceOrderTime.prototype.getLngLatPoi = function(callback){		var me = this;		AMapUtils.getAddressPoi(me.userAddress, {			successCB : function(location) {				var theLnglatPoi = location.geocodes[0].location;				me.lngLatPoi = theLnglatPoi.lng + ',' + theLnglatPoi.lat;				callback();			},			errorCB : function(){				me.lngLatPoi = null;//查询出错				callback();			}		});	}	//到处到特定的作用域中	define('ServiceOrderTime',ServiceOrderTime);

require(["ServiceOrderTime","ServiceOrderTimes","Stylist","ServiceOrder"],function(ServiceOrderTime,ServiceOrderTimes,Stylist,ServiceOrder){	//prepare data	var serviceOrder = new ServiceOrder();	。。。});
