随机生成uuid

export const GenerateUuid = () => {
let s: string[] = [],
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
// @ts-ignore
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] = ‘-’;

let uuid = s.join(‘’);

return uuid;
