对象初始化完成后，通过对象修改format后不生效 

var startDate = laydate.render({
                elem: '#startDate', //指定元素 #startDate是一个input
                type: 'date',
                format: 'yyyy年MM月dd日',
                isInitValue: true, //是否允许填充初始值，默认为 true
                done: function(value, date, endDate) {
                    /*回调里修改了type 和format 发现type的修改生效了，但是formar的修改没有生效，看源码发现是没有更新this.format、that.EXP_IF和that.EXP_SPLIT。（PS:这里只是举例，实际项目中是通过别的按钮触发改变type和format 事件的。） */
                    startDate .config.type = 'month';
                    startDate .config.format = 'yyyy年MM月';
                }
            });
