上程式碼

        $('.datetime').each(function () {
            dateBind(this)
        });

        function dateBind(this_){
            laydate.render({
                elem: this_
                , type: 'month'
                , closeStop: this_
                , trigger: 'click'

            });
        }
 

如需二次電泳那麼必須 獲取到 lay-key這個屬性

var num = 0;
        $('.add-min').on('click','.add-experience',function(){
            let dom = $('.experience').eq(0);
            let html = dom.clone(true);
            //刪除
            let html2 = '<a href="javascript:;" class="del-experience"><i class="layui-icon layui-icon-close-fill font-size-40"></i></a>
 
';
            $(html).append(html2);

            //時間日期
            if(num == 0){
                num = $('.experience').eq(-1).find('.datetime').eq(-1).attr('lay-key');
            }
            $(html).find('.datetime').each(function () {
                num = parseInt(num)+1;
                $(this
 
).attr('lay-key',num);
                dateBind(this)
                console.log(num)
            });

            $(this).parent().before(html);
            form.render(null, 'form-test');
        })
