JavaScript generation uuid (Method 2)

You can create a UUID directly online, preview it,

This site is good, you can choose the UUID version, you can also directly remove the underline, easy to use Ah, haha

On creation of a UUID object, set it ' s initial valuefunction UUID () {this.id = This.createuuid ();} When asked what's this Object is, lie and return it ' s valueUUID.prototype.valueOf = function () {return this.id;}; UUID.prototype.toString = function () {return this.id;};////INSTANCE Specific methods//uuid.prototype.createuuid = function () {////Loose Interpretation of the specification DCE 1.1:remote Procedure call//since JavaScript do ESN ' t allow access to internal systems, the last bits per//Of the node section was made up using a series of random num    Bers (6 octets long).    var dg = new Date (1582, 10, 15, 0, 0, 0, 0);    var dc = new Date ();    var t = dc.gettime ()-dg.gettime ();    var tl = uuid.getintegerbits (t,0,31);    var TM = uuid.getintegerbits (t,32,47); var THV = uuid.getintegerbits (t,48,59) + ' 1 ';    Version 1, security version is 2 var csar = Uuid.getintegerbits (Uuid.rand (4095), 0,7);   var CSL = Uuid.getintegerbits (Uuid.rand (4095), 0,7); Since detection of anything about the Machine/browser are far from buggy,//include some more random numbers here    If NIC or an IP can is obtained reliably, that should is put in//here instead. var n = uuid.getintegerbits (Uuid.rand (8191), 0,7) + uuid.getintegerbits (Uuid.rand (8191), 8,15) + UUID.

Calling method: UUID.prototype.createUUID ()
