Style a button as a link

I have an invisible form that I want the user to submit with a link, keeping the illusion that it's not a form. I know you could submit the form with javascript (onclick="document.formName.submit();), but then if the user doesn't have javascript enabled, I'd still have to use a noscript tag and they'd see it as a form button. The solution is to style the button with CSS. something like:

.sublink {
color: #00f;
background-color: transparent;
text-decoration: underline;
border: none;
cursor: pointer;
}

Then the html would be:

<input type="submit" class="sublink" value="Click this">
