How can i process this form alone

I have this function on an html form, the form script there is this
<script type="text/javascript">
var conf = {
isVip:false,
isMem:false
};
</script>
and here is the the button, the button is to process two form in the html,
here is the button.
<li class="current">
<a href="#" onclick="submitAction('process.php')">Ãâ·ÑÓÊÏäµÇ¼</a>
</li>
<li>
<a href="#" onclick="submitAction('process.php')"><span
class="vip"></span>VIPSubmit</a>
</li>
<a href="#" class="loginBtn"
Here is the form
<form name="vip_login" method="post" action="process.php">
<input tabindex="1" id="vipname" type="text" class="username"
name="username" value=""/><span class="vipDomain">@name.com</span>
<input tabindex="2" id="vippassword" type="password"
class="password" name="password" value=""/>
My question is, how do i make the btn to process my form alone and send
data to external process.php function.
