JS 格式化时间字符串

// 格式时间字符串
formatDateTimeStr(date, type) {
  if (date === '' || !date) {
    return ''
  }
  var dateObject = new Date(date)
  var y = dateObject.getFullYear()
  var m = dateObject.getMonth() + 1
  m = m < 10 ? ('0' + m) : m
  var d = dateObject.getDate()
  d = d < 10 ? ('0' + d) : d
  var h = dateObject.getHours()
  h = h < 10 ? ('0' + h) : h
  var minute = dateObject.getMinutes()
  minute = minute < 10 ? ('0' + minute) : minute
  var second = dateObject.getSeconds()
  second = second < 10 ? ('0' + second) : second
  if (type === 1) { // 返回年月日
    return y + '-' + m + '-' + d
  } else if (type === 2) { // 返回年月日 时分秒
    return y + '-' + m + '-' + d + ' ' + h + ':' + minute + ':' + second
  }
},
