Why Messages Shown On Loading Form

When I have this form loading its loading both messages when I told it to hide it and don't know why. I looked inside the source code of the form and it's not saying the jquery function is involved.

Code:
<script type="text/javascript">
$(document).ready(function() {
$('div.message message-error').hide();
$('div.message message-success').hide();
$("input.submit").click(function() {
$('div.message message-error').hide();
var divisionname = $("input#divisionname").val();
if (divisionname == "") {
$("div.message message-error").show();
$("input#name").focus();
return false;
} .....
