Vue使用 uuid

 created() {
    this.uuid()
    this.imgurl="http://www.ironbox1.com/j/code/image?deviceId="+this.text
  },
  methods: {
    // 获取uuid
    uuid() {
      var s = [];
      var hexDigits = "0123456789abcdef";
      for (var i = 0; i < 36; 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("");
      this.text = uuid
      console.log(this.text)
  },
  }
