常用过滤器

1、计算某个日期距当前时间多少分钟/时/天

/**
 * @param {number} time
 */
export function timeAgo(time) {
  const between = Date.now() / 1000 - Number(time)
  if (between < 3600) {
    return pluralize(~~(between / 60), ' minute')
  } else if (between < 86400) {
    return pluralize(~~(between / 3600), ' hour')
  } else {
    return pluralize(~~(between / 86400), ' day')
  }
}

2、首字母大写

/**
 * Upper case first char
 * @param {String} string
 */
export function uppercaseFirst(string) {
  return string.charAt(0).toUpperCase() + string.slice(1)
}

3、秒时间戳转 yyyy-MM-dd HH:mm:ss

/**
 * 
 * @param {*} originVal 传进来的时间戳
 * @returns yyyy-MM-dd HH:mm:ss
 */
export function timeStampFormat(originVal) {
  const dt = new Date(originVal * 1000)
  const y = dt.getFullYear()
  const m = (dt.getMonth() + 1 + '').padStart(2, '0')
  const d = (dt.getDate() + '').padStart(2, '0')

  const hh = (dt.getHours() + '').padStart(2, '0')
  const mm = (dt.getMinutes() + '').padStart(2, '0')
  const ss = (dt.getSeconds() + '').padStart(2, '0')
  return `${y}-${m}-${d} ${hh}:${mm}:${ss}`
}

4、国际时间2018-11-04T08:00:00.000+0000  转 yyyy-MM-dd HH:mm:ss

 /**

 *

 * @param {*} date

 * @returns

 */

export function dateTimeFormat(date) {
  const json_date = new Date(date).toJSON()
  console.log(json_date)
  return new Date(+new Date(json_date) + 8 * 3600 * 1000).toISOString().replace(/T/g, ' ').replace(/\.[\d]{3}Z/, '')
}

5、国际时间 2018-11-04T08:00:00.000+0000 转日期 yyyy-MM-dd

/**
 *
 * @param {*} date 
 * @returns 
 */
export function dateTimeFormatData(date) {
  const d = new Date(date)
  return d.getFullYear() + '-' + (d.getMonth() + 1 < 10 ? '0' + (d.getMonth() + 1) : d.getMonth() + 1) + '-' + (d.getDate() < 10 ? '0' + d.getDate() : d.getDate())
}
