如何在js获取UUID

1.ent_UUID.js

function UUID(){
    this.id = this.createUUID();
}
UUID.prototype.valueOf = function(){ return this.id; };
UUID.prototype.toString = function(){ return this.id; };
UUID.prototype.createUUID = function(){
    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);
    var n = UUID.getIntegerBits(UUID.rand(8191),0,7) + 
            UUID.getIntegerBits(UUID.rand(8191),8,15) + 
            UUID.getIntegerBits(UUID.rand(8191),0,7) + 
            UUID.getIntegerBits(UUID.rand(8191),8,15) + 
            UUID.getIntegerBits(UUID.rand(8191),0,15); // this last number is two octets long
    return tl + tm  + thv  + csar + csl + n; 
};
 
UUID.getIntegerBits = function(val,start,end){
 var base16 = UUID.returnBase(val,16);
 var quadArray = new Array();
 var quadString = '';
 var i = 0;
 for(i=0;i

2.在jsp页面引入

3.在需要调用的js页面直接调用即可

var m_id = UUID.prototype.createUUID();
