前端生成uuid

 //uuid
 static 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("");
     return uuid;
 }
