Js/JQuery生成不重复的UUID
javascript代码
function guid () {
return 'xxxxxxxx-xxxx-4xxx-yxxx-xxxxxxxxxxxx'.replace(/[xy]/g, function (c) {
var r = Math.random() * 16 | 0
var v = c === 'x' ? r : (r & 0x3 | 0x8)
return v.toString(16)
})
}
去除横线
function guidShort () {
return guid ().replace("-","");
}
显示结果
UUID完整:4915d2f4-2e83-47d6-bc76-e321caeff812
UUID不含-:f5e53a50fda8-4c8d-a4fb-04821ac932d0
