laydate根据开始时间或者结束时间限制范围 laydate怎样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;
    }

  });
