laydate如何根据开始时间或者结束时间限制范围

$(window).load(function(){//初始化时间控件
 var cartimeDate = laydate.render({
 elem: '#cartime' //用车时间
 ,type: 'datetime'
 ,format: 'yyyy-MM-dd HH:mm'
 ,done:function(value, date){
 returntimeDate.config.min=getDateArray(date);//重点
 }
 });

 var returntimeDate = laydate.render({
 elem: '#returntime' //预计回车时间
 ,type: 'datetime'
 ,format: 'yyyy-MM-dd HH:mm'
 ,done:function(value, date){
 cartimeDate.config.max=getDateArray(date);//重点
 }
 });

 function getDateArray(date){//获取时间数组
 var darray={};
 darray.year=date.year;
 darray.month=date.month - 1;
 var day=date.date;
 if(date.hours == 23 && date.minutes == 59 && date.seconds == 59){
 day = day + 1;
 }else{
 darray.hours = date.hours;
 darray.minutes = date.minutes;
 darray.seconds = date.seconds;
 }
 darray.date=day;
 return darray;
 }

 });
