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

What am I missing??

js/app.js 
//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($("form span").val().length > 8) {
      //Hide hint if valid
      $("form span").next().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
index.html 
<!DOCTYPE html>

    <title>Sign Up Form</title>
    <link rel="stylesheet" href="css/style.css" type="text/css" media="screen" title="no title" charset="utf-8">

    <form action="#" method="post">

            <input id="username" name="username" type="text">

        <p>
            <label for="password">Password</label>
            <input id="password" name="password" type="password">
            <span>Enter a password longer than 8 characters</span>
        </p>
        <p>
            <label for="confirm_password">Confirm Password</label>
            <input id="confirm_password" name="confirm_password" type="password">
            <span>Please confirm your password</span>
        </p>
        <p>
            <input type="submit" value="SUBMIT">

$("form span") is referring to all the <span> elements that are inside the form element. So when you add the .next() method to it, it looks for the element that comes next to the span.

You need to direct it to the $("#password") element, so that the next element is the <span>Enter a password longer than 8 characters</span> which you want to be hidden.

Update your code as following and it will do just fine. Hope this helps!

//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($("form span").val().length > 8) {
      //Hide hint if valid
      $("#password").next().hide();
    } else {
      //else show hint
      $("#password").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
