I've finally got back to this. I just cannot get it to do anything
other than submit the form. When I click the 'Preview' button, the
form submits, I get a success message, and go back to the index page -
which is exactly what happens if I submit the form using the regular
Submit button.
I'd really appreciate any help - I'm new to Ajax, so I'm sure I'm just
doing something stupid, but I don't know where to start looking for
it.
Thanks!

Here's what I have so far:
PAGES_CONTROLLER.PHP:
class PagesController extends AppController {
var $helpers = array('Html', 'Form', 'Javascript', 'Time', 'Fck',
'Ajax');
... $uses, some functions etc ...
function admin_edit($id = null) {
$this->checkSession();
$this->layout = 'admin';
if (!$id && empty($this->data)) {
$this->Session->setFlash('Invalid page requested',
'flash_failure');
$this->redirect('/admin/pages/index');
exit();
}
if (!empty($this->data)) {
if ($this->Page->save($this->data)) {
$this->Session->setFlash('Changes saved', 'flash_success');
$this->redirect('/admin/pages/index');
exit();
}else {
$this->Session->setFlash('Unable to save changes. Please correct
errors below', 'flash_failure');
}
}else {
$pagelist = $this->Page->find('list', array('conditions' =>
array('visible' => 1, 'parent_id' => 0, 'title !=' => 'Home')));
$this->set('pagelist', $pagelist);
if (empty($this->data)) {
$this->data = $this->Page->read(null, $id);
}
}
}
function admin_preview($id = null) {
if (!empty($this->data)) {
$this->Page->save($this->data);
$page = $this->Page->read(null, $id);
}else if (isset($id)) {
$page = $this->Page->read(null, $id);
}else {
return null;
}
$this->set('page', $page);
$this->render('view');
}
}
IN VIEWS/PAGES/ADMIN_EDIT.PHP (I've left out a few divs, inputs etc.
to make it shorter):
<div class="pages form">
<?php echo $form->create('Page');?>
<fieldset>
<?php
echo $form->input('id');
echo '<div class="input textarea">';
echo $form->label('Content') . '<br/>';
echo $form->input('content', array('type' => 'textarea', 'rows' =>
20, 'cols' => 50, 'label' => ''));
echo $fck->load('Page/content', 'Cake');
echo '</div>';
echo '<input type="submit" value="Preview Page" id="preview_btn" /
>';
echo '<input type="submit" value="Save Changes" />';
echo '</form>';
?>
</fieldset>
</div>
<div id="page_modal"><div id="page_modal_content"></div></div>
<script language="text/javascript">
$('#preview_btn').click(function(e) {
$(this).parents('form').ajaxSubmit({
url: '/admin/pages/preview',
error: function(XMLHttpRequest, textStatus, errorThrown)
{
alert(textStatus);
},
success: function(responseText){
$
('#page_modal').jqmShow().find('#page_modal_content').html(responseText);
}
});
e.preventDefault();
});
</script>
