Returning to anchor point after form submit

Does anyone know how to do the following? I’m not even sure if it is
possible without Ajax…

I have a form for a contact’s details. The form also contains fields
for 1 or more associated telephones. The form has a “real” submit
button, as well as other submit buttons that are used to add/remove
telephone fields.

When the user clicks the “add another telephone” button in the form,
the edit view is rendered, and from the user’s point of view, the
screen scrolls all the way back to the top. Is there a way, after
submitting the form, to render the form but jump to an anchor within
the page (so the screen remains centered on the telephone)? Without

Thanks in advance,
