格式化日期 返回yyyy-mm-dd hh:mm:ss的形式

   function formDate(data) {
            // 判断参数date是否是日期对象
            if (!(data instanceof Date)) {
                console.error('data不是日期对象')
                return;
            }
            var year = data.getFullYear(),
                month = data.getMonth() + 1,
                day = data.getDate(),
                hour = data.getHours(),
                minute = data.getMinutes(),
                second = data.getSeconds()
            month = (month < 10) ? '0' + month : month;
            day = (day < 10) ? '0' + day : day;
            hour = (hour < 10) ? '0' + hour : hour;
            minute = (minute < 10) ? '0' + minute : minute;
            second = (second < 10) ? '0' + second : second;

            return year + '-' + month + '-' + day + ' \r' + hour + ':' + minute + ':' + second
        }
