'0' + month : month;day = day < 10 ? '0' + day : day;hours = hours < 10 ? '0' + hours : hours;minutes = minutes < 10 ? '0' + minutes : minutes;seconds = seconds < 10 ? '0' + seconds : seconds;// 星期数组const weekdays = ['星期日', '星期一', '星期二', '星期三', '星期四', '星期五', '星期六'];// 格式化日期时间this.datetimeStr = year + "年" + month + "月" + day + "日 " + weekdays[weekday] + " " + hours + ":" + minutes + ":" + seconds;}}}
