图标触发laydate日期

Question

这是我的代码，最后点击#beginTimeIcon图标触发 start 的日期，点击#endTimeIcon图标触发 end 的日期,现在不知道该怎么做了，，我用的是最新版laydate

var start = laydate.render({
        elem: '#beginTime',
        min: '1900-1-1 00:00:00',
        max: '2099-6-16 23:59:59',
        trigger: 'click', //采用click弹出
        done: function(value, date, endDate){
            end.config.min = {
                year: date.year,
                month: date.month - 1,
                date: date.date,
                hours: date.hours,
                minutes: date.minutes,
                seconds: date.seconds
            }; //开始日选好后，重置结束日的最小日期
            end.config.value = {
                year: date.year,
                month: date.month - 1,
                date: date.date,
                hours: date.hours,
                minutes: date.minutes,
                seconds: date.seconds
            }; //将结束日的初始值设定为开始日
        }
    });
    var end = laydate.render({
        elem: '#endTime',
        min: '1900-1-1 00:00:00',
        max: '2099-6-16 23:59:59',
        trigger: 'click', //采用click弹出
        done: function(value, date, endDate){
            start.config.max = {
                year: date.year,
                month: date.month - 1,
                date: date.date,
                hours: date.hours,
                minutes: date.minutes,
                seconds: date.seconds
            }; //结束日选好后，重置开始日的最大日期
        }
    });

    $("#beginTimeIcon").on("click",function () {
        laydate.render(start);
    });
