Simple and secure way of confirming a deletion

Connected to WebmasterWorld JS Forum:

This method submits a form (the action directs to the delete page) and the onsubmit event confirms the action with the user. WARNING: This method will still delete if JavaScript is disabled!

<script type="text/javascript">
function confirmDelete() { 
  return confirm("Are you sure you want to delete?");   
} 
</script>
<form action="confirm_delete_action.php" onsubmit="return confirmDelete();"> 
  <div> 
    <input type="submit" name="delete" value="Delete"> 
  </div> 
</form>
</script>

Perhaps a slightly more secure solution is to do everything in JavaScript, including the redirect. But if someone takes a look at the code they can then see the intended action and bypass the confirmation anyway - but then it is still a deliberate action. This is not a good solution, as it relies on JavaScript being enabled in the browser for it to work.

function performDelete(DestURL) {
	var ok = confirm("Are you sure you want to delete?");  
	if (ok) {location.href = DestURL;}
	return ok;
} 
<a href="nojs.html" onclick="performDelete('confirm_delete_action.php'); return false;">Delete</a>

Need to send a confirmation to the destination (delete) page that it has been confirmed
