JS毫秒数格式化为yyyy-MM-dd hh:mm:ss.S字符串

longDataToStr(longTypeDate) {
      var date = new Date(longTypeDate)
      var y = date.getFullYear()
      var m = date.getMonth() + 1
      m = m < 10 ? ('0' + m) : m
      var d = date.getDate()
      d = d < 10 ? ('0' + d) : d
      var h = date.getHours()
      h = h < 10 ? ('0' + h) : h
      var minute = date.getMinutes()
      var second = date.getSeconds()
      var Millisecond = date.getMilliseconds()
      minute = minute < 10 ? ('0' + minute) : minute
      second = second < 10 ? ('0' + second) : second
      return y + '-' + m + '-' + d + ' ' + h + ':' + minute + ':' + second + '.' + Millisecond
    }
