laydate 限制结束日期不能大于起始日期

时间选择器在选择的时候，同时配置了另一个时间选择器内的参数

  <div class="form-group">
     <label for="exampleInputName2">停留时间:</label>
     <input type="text"  class="form-control" name="open"  id="start_time" placeholder="点击选择开始时间" required>
  </div>
  <div class="form-group">
     <label for="exampleInputEmail2">到</label>
     <input type="text" class="form-control"  name="close" id="end_time" placeholder="点击选择结束时间" required>
  </div>

<script src="{{asset('/js/laydate.js')}}"></script>

<script>
    var startDate = laydate.render({
        elem: '#start_time',
        type: 'datetime',
        format: 'yyyy-MM-dd HH:mm:ss',
        done: function(value, date){
            endDate.config.min ={
                year:date.year,
                month:date.month-1,
                date: date.date,
                hours: 0,
                minutes: 0,
                seconds : 0
            };
        }
    });
    var endDate = laydate.render({
        elem: '#end_time',
        type: 'datetime',
        format: 'yyyy-MM-dd HH:mm:ss',
        done: function(value,date){
            startDate.config.max={
                year:date.year,
                month:date.month-1,//注意是month-1，写在date上的话你后边的日期选择不了
                date: date.date,
                hours: 0,
                minutes: 0,
                seconds : 0
            }
        }
    });
