What would be the best approach to creating a 8 character random password containing a-z, A-Z and 0-9?

Absolutely no security issues, this is merely for prototyping, I just want data that looks realistic.

I was thinking a for (0 to 7) Math.random to produce ASCII codes and convert them to characters. Do you have any other suggestions?

I would probably use something like this:

function generatePassword() {

    var length = 8,

        charset = abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789,

        retVal = ;

    for (var i = 0, n = charset.length; i < length; ++i) {

        retVal += charset.charAt(Math.floor(Math.random() * n));

    }

    return retVal;

}

That can then be extended to have the length and charset passed by a parameter.
