Example #9: generating password with fake progress

Of course generating a random password is done in less than a millisecond. But you want to simulate heavy computational things going on – just for a nice user experience.

Given that you have a method which adds one random character at a time to an input value,
var alphabet = '012345689abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ';
function addRandomChar() {
  return $(this).val() + alphabet[Math.floor(Math.random() * alphabet.length)];
then you can use that to build our password generator.

Enter your new password, please:
