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

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 :(

Answer 3

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();
}

Answer 4

Try this out...

function createGuid () {
  for (var i=5, out=[]; i--;) {
    out.push((Math.random()*58786559+1679615|0).toString(36));
  }
  return out.join('-').toUpperCase();
}

alert(createGuid());
