详解vue如何获取当前系统时间

// 标准时间格式转化为年月日时分秒
export function ssDateTimeFn(timestamp) {
  if (!timestamp) {
    return timestamp
  }
  // timestamp是整数，否则要parseInt转换,不会出现少个0的情况
  const time = new Date(timestamp)
  const year = time.getFullYear()
  const month = time.getMonth() + 1
  const date = time.getDate()
  const hours = time.getHours()
  const minutes = time.getMinutes()
  const seconds = time.getSeconds()
  return year + '-' + add0(month) + '-' + add0(date) + ' ' + add0(hours) + ':' + add0(minutes) + ':' + add0(seconds)
}

import {
  ssDateTimeFn
} from '@/utils/commonss' // 公共事件引入使用

ssDateTimeFn(new Date())

// 标准时间格式转化为年月日时分
function mmDateTimeFn(timestamp) {
  if (!timestamp) {
    return timestamp
  }
  // timestamp是整数，否则要parseInt转换,不会出现少个0的情况
  const time = new Date(timestamp)
  const year = time.getFullYear()
  const month = time.getMonth() + 1
  const date = time.getDate()
  const hours = time.getHours()
  const minutes = time.getMinutes()
  // const seconds = time.getSeconds()
  return year + '-' + add0(month) + '-' + add0(date) + ' ' + add0(hours) + ':' + add0(minutes)
}

// 年月日 不带时分
function dateFormat(timestamp) {
  if (!timestamp) {
    return timestamp
  }
  // timestamp是整数，否则要parseInt转换,不会出现少个0的情况
  const time = new Date(timestamp)
  const year = time.getFullYear()
  const month = time.getMonth() + 1
  const date = time.getDate()
  return year + '-' + add0(month) + '-' + add0(date)
}
