34 前端生成32位UUID

// 生成32位uuid
    uuid2() {
      var s = []
      var hexDigits = '0123456789abcdef'
      for (var i = 0; i < 32; i++) {
        s[i] = hexDigits.substr(Math.floor(Math.random() * 0x10), 1)
      }
      s[14] = '4' // bits 12-15 of the time_hi_and_version field to 0010
      s[19] = hexDigits.substr((s[19] & 0x3) | 0x8, 1) // bits 6-7 of the clock_seq_hi_and_reserved to 01
      s[8] = s[13] = s[18] = s[23]
      var uuid = s.join('')
      return uuid
    }

效果如下：
