Here is a way to globally replace all the cancel links on the confirm delete node pages...
<?php
function MYMODULE_form_alter($form_id, &$form) {
// ...code...
if ($form_id == 'node_delete_confirm') {
_MYMODULE_form_alter_node_delete_confirm($form);
}
// ...code...
}
function _MYMODULE_form_alter_node_delete_confirm(&$form) {
if (is_array($form['actions']['cancel'])) {
// convert the html from the link into an xml object to get at its attributes
$o = simplexml_load_string($form['actions']['cancel']['#value']);
// replace the link with a new button
// NOTE: jQuery is added afterwards to convert the button type from a submit to a button
$form['actions']['cancel'] = array(
'#type' => 'button',
'#value' => 'Cancel',
'#attributes' => array(
'onClick' => "window.location = '" . urldecode($o['href']) . "';",
),
'#suffix' => "
<script type='text/javascript'>
$(document).ready(function(){
$('form#node-delete-confirm input#edit-cancel').attr('type', 'button');
});
</script>"
);
}
}
?>
