When I type a password in the password field greater than 8 characters the input disappears not the hint. Fix it.

//Problem: Hints are shown even when form is valid
//Solution: Hide and show them at appropriate times

//Hide hints
$("form span").hide();

function passwordEvent(){
    //Find out if password is valid  
    if($(this).val().length > 8) {
      //Hide hint if valid
      $("form span").hide();
    } else {
      //else show hint
      $("form span").next().show();
    }
}


//When event happens on password input
$("#password").focus(passwordEvent).keyup(passwordEvent);

//When event happens on confirmation input
  //Find out if password and confirmation match
    //Hide hint if match
    //else show hint
