1.new Date( ) 输出
Fri Mar 06 15:18:29 GMT+0800 (中国标准时间)
2.date.getTime() 得到时间戳 输出
1583479672091
3.date.setTime(); 设置时间 （时间戳）
4.date.getDate()、date.getMonth() 输出
年月日
5.将中国标准时间转化未年月日（-03-13）
getTime(time) {var date = new Date(time);var day = ("0" + date.getDate()).slice(-2);//格式化月，如果小于9，前面补0var month = ("0" + (date.getMonth() + 1)).slice(-2);//拼装完整日期格式var today = date.getFullYear() + "-" + month + "-" + day;return today;},
5.将中国标准时间转化为两个相隔一周的时间
getThirtyTime() {const end = new Date();const start = new Date();start.setTime(start.getTime() - 3600 * 1000 * 24 * 7);this.searchForm.orderTime = [this.getTime(start), this.getTime(end)];},
重要例子如下
<el-form-item label="时段："><el-button type="primary" @click="today" plain>今天</el-button><el-button type="primary" @click="yestoday" plain>昨天</el-button><el-button type="primary" @click="weekly" plain>近7天</el-button><el-button type="primary" @click="month" plain>近30天</el-button></el-form-item>today() {const end = new Date();const start = new Date();start.setTime(start.getTime());this.searchForm.orderTime = [this.getTime(start), this.getTime(end)];},yestoday() {//const end = new Date();const start = new Date();start.setTime(start.getTime() - 3600 * 1000 * 24 * 1);this.searchForm.orderTime = [this.getTime(start), this.getTime(start)];},weekly(){const end = new Date();const start = new Date();start.setTime(start.getTime() - 3600 * 1000 * 24 * 7);this.searchForm.orderTime = [this.getTime(start), this.getTime(end)];},month(){const end = new Date();const start = new Date();start.setTime(start.getTime() - 3600 * 1000 * 24 * 30);this.searchForm.orderTime = [this.getTime(start), this.getTime(end)];},getTime(time) {var date = new Date(time);var day = ("0" + date.getDate()).slice(-2);//格式化月，如果小于9，前面补0var month = ("0" + (date.getMonth() + 1)).slice(-2);//拼装完整日期格式var today = date.getFullYear() + "-" + month + "-" + day;return today;},getThirtyTime() {const end = new Date();const start = new Date();start.setTime(start.getTime() - 3600 * 1000 * 24 * 7);this.searchForm.orderTime = [this.getTime(start), this.getTime(end)];},
