[jQuery] Using a button that doesn't submit?

[jQuery] Using a button that doesn't submit?


Hi, all...
I'm using some jQuery to add file fields to a page.
I'm using a button to trigger the jQuery.
<button>Add New Image Field</button>
In IE6 and IE7 the button just adds fields like I want,
however, in FF2, the button submits the form.
How can I use the button with form submission?
I found plenty of info on Google about submitting a form
without a button, nothing on using a button in a form
with causing submission...
