I need help

Challenge Task 1 of 1

On line 51 on app.js, use the focus and keyup event handlers to execute the confirmPasswordEvent. Important: The code you write in each task should be added to the code written in the previous task.

i dont know what to do

js/app.js 
//Problem: Hints are shown even when form is valid
//Solution: Hide and show them at appropriate times
var $password = $("#password");
var $confirmPassword = $("#confirm_password");

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

function isPasswordValid() {
  return $password.val().length > 8;
}

function arePasswordsMatching() {
  return $password.val() === $confirmPassword.val();
}

function canSubmit() {
  return isPasswordValid() && arePasswordsMatching();
}

function passwordEvent(){
    //Find out if password is valid  
    if(isPasswordValid()) {
      //Hide hint if valid
      $password.next().hide();
    } else {
      //else show hint
      $password.next().show();
    }
}

function confirmPasswordEvent() {
  //Find out if password and confirmation match
  if(arePasswordsMatching()) {
    //Hide hint if match
    $confirmPassword.next().hide();
  } else {
    //else show hint 
    $confirmPassword.next().show();
  }
}

function enableSubmitEvent() {
  $("#submit").prop("disabled", !canSubmit());
}

//When event happens on password input
$password.focus(passwordEvent).keyup(passwordEvent).keyup(confirmPasswordEvent).keyup(enableSubmitEvent);

//When event happens on confirmation input
$con.focus(confirmPasswordEvent).keyup(confirmPasswordEvent);

Look at the last line of the app.js file. $con is suppose to be $confirmPassword.

Correct Answer ...

$confirmPassword.focus(confirmPasswordEvent).keyup(confirmPasswordEvent).keyup(enableSubmitEvent);

//Problem: Hints are shown even when form is valid //Solution: Hide and show them at appropriate times var $password = $("#password"); var $confirmPassword = $("#confirm_password");

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

function isPasswordValid() { return $password.val().length > 8; }

function arePasswordsMatching() { return $password.val() === $confirmPassword.val(); }

function canSubmit() { return isPasswordValid() && arePasswordsMatching(); }

function passwordEvent(){ //Find out if password is valid
if(isPasswordValid()) { //Hide hint if valid $password.next().hide(); } else { //else show hint $password.next().show(); } }

function confirmPasswordEvent() { //Find out if password and confirmation match if(arePasswordsMatching()) { //Hide hint if match $confirmPassword.next().hide(); } else { //else show hint $confirmPassword.next().show(); } }

function enableSubmitEvent() { $("#submit").prop("disabled", !canSubmit()); }

//When event happens on password input $password.focus(passwordEvent).keyup(passwordEvent).keyup(confirmPasswordEvent).keyup(enableSubmitEvent);

//When event happens on confirmation input //$confirmPassword.keyup(enableSubmitEvent);

// Correct Answer line 51

$confirmPassword.focus(confirmPasswordEvent).keyup(confirmPasswordEvent).keyup(enableSubmitEvent);

enableSubmitEvent();
