それぞれのフィールドの下にエラー メッセージを表示し、フォームの下に成功メッセージを表示したいと考えています。成功メッセージを取得できますが、フィールドが空であってもエラーメッセージが表示されません。以下は私のコードです:-
contact.html
<!DOCTYPE html>
<html>
<head>
<link rel="stylesheet" media="screen" href="styles.css" >
<script type="text/javascript" src="my.js"></script>
<script src="http://code.jquery.com/jquery-latest.js"></script>
<script>
$(document).ready(function(){
$('#submit').click(function(e){
e.preventDefault();
$.post("send.php", $("#mycontactform").serialize(), function(response) {
$('#success').html(response);
//$('#success').hide('slow');
});
return false;
});
});
</script>
<script type="text/javascript">
function validateRoleForm() {
var name = document.getElementById('name').value;
if (name == "" || name == null) {
$('#errortext1').html('please enter name.');
return false;
}
else if{
var name = document.getElementById('email').value;
if (name == "" || name == null) {
$('#errortext2').html('please enter email.');
return false;
}
else if{
var name = document.getElementById('message').value;
if (name == "" || name == null) {
$('#errortext3').html('please enter message.');
return false;
}
else {
$('#success').html('Mail sent');
return true;
}
}
</script>
</head>

私を助けてください。どこが間違っているのかわかりませんか？
