2,040 PointsReturn true - form validation
Hi, I am not sure what "true" means? Is it word true or?
Here is my code, thanks
//Problem: Hints are shown even when form is valid
//Solution: Hide and show them at appropriate times
var $password = $("#password");
var $confirmPassword = $("#confirm_password");
var $username = $("#username");
//Hide hints
$("form span").hide();
function isUsernamePresent() {
if($username.val().lenght > 0) {
return "true"; // ????
}
}
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());
}
function usernameEvent() {
if(isUsernamePresent()) {
$username.next().hide();
} else {
$username.next().show();
}
}
//When event happens on password input
$password.focus(passwordEvent).keyup(passwordEvent).keyup(confirmPasswordEvent).keyup(enableSubmitEvent);
//When event happens on confirmation input
$confirmPassword.focus(confirmPasswordEvent).keyup(confirmPasswordEvent).keyup(enableSubmitEvent);
$username.focus(usernameEvent).keyup(usernameEvent).keyup(enableSubmitEvent);
enableSubmitEvent();

return true;
You should remove the " ".

Python Web Development Techdegree Student 38,322 PointsOh sorry - I maybe have miss-understood your question.
You need to write the function like this:
function isUsernamePresent() {
return $username.val().length > 0;
}
