Javascript中生成 Guid

写一个在JS中生成Guid的函数 var emptyGuid='00000000-0000-0000-0000-000000000000'

function newGuid() { return emptyGuid.replace(/0+/g, function (o) {return Math.random().toString(16).substr(2, o.length)})}

让Guid中只包含10进制数字:

var emptyGuid='00000000-0000-0000-0000-000000000000'

function newGuid() { return emptyGuid.replace(/0+/g, function (o) {return Math.random().toString().substr(2, o.length)})}
