I need to have a script that generates random numbers and letters with a form that looks like this:

M3KRT-CKKYV-YH4G4-YXP42-46FMT

Prefer jQuery, or javascript. I know how to generate number when the button is click using the .click() method in jQuery. But I can not find out how to actually make the code :(

像这样：在JavaScript中创建GUID / UUID？

Modified this example a little:

Create GUID / UUID in JavaScript?

And came up with this:

function S5() {
    return (((1 + Math.random()) * 0x100000) | 0).toString(16).substring(1);
}
function guid() {
    return (S5() + "-" + S5() + "-" + S5() + "-" + S5() + "-" + S5()).toUpperCase();
}
