The RFC-compliant UUID generator for JavaScript.
See RFC 4122 http://www.ietf.org/rfc/rfc4122.txt.
Generates RFC 4122 compliant UUIDs.
Version 4 UUIDs (UUIDs from random numbers) and version 1 UUIDs (time-based UUIDs) are available.
UUID object allows a variety of access to the UUID including access to the UUID fields.
Low timestamp resolution of JavaScript is compensated by random numbers.
Load src/uuid.js to get full functionality. If you only need UUID.generate() method, dist/uuid.core.js satisfies your needs.
// the simplest way to get an UUID (as a hexadecimal string)
document.writeln(UUID.generate()); // "0db9a5fa-f532-4736-89d6-8819c7f3ac7b"
// create a version 4 (random-numbers-based) UUID object
var objV4 = UUID.genV4();
// create a version 1 (time-based) UUID object
var objV1 = UUID.genV1();
// create an UUID object from a hexadecimal string
var uuid = UUID.parse("a0e0f130-8c21-11df-92d9-95795a3bcd40");
// UUID object as a string
document.writeln(uuid.toString()); // "a0e0f130-8c21-11df-92d9-95795a3bcd40"
document.writeln(uuid.hexString); // "a0e0f130-8c21-11df-92d9-95795a3bcd40"
document.writeln(uuid.bitString); // "101000001110000 ... 1100110101000000"
document.writeln(uuid.urn); // "urn:uuid:a0e0f130-8c21-11df-92d9-95795a3bcd40"
// compare UUID objects
document.writeln(objV4.equals(objV1)); // false
// show version numbers
document.writeln(objV4.version); // 4
document.writeln(objV1.version); // 1
// get UUID field values in 3 different formats by 2 different accessors
document.writeln(uuid.intFields.timeLow); // 2699096368

document.writeln(uuid.hexFields.timeHiAndVersion); // "11df"
document.writeln(uuid.intFields.clockSeqHiAndReserved); // 146
document.writeln(uuid.bitFields.clockSeqLow); // "11011001"
document.writeln(uuid.hexFields.node); // "95795a3bcd40"
document.writeln(uuid.intFields[0]); // 2699096368
