For the reasons detailed below, `onClick' (or `onclick' in XHTML) is the 
wrong event-handler attribute (and `click' is the wrong event) to use here.

You are still wrong about which language can be used where, and you really 
do not know what JavaScript is.

However, more important to notice is that the drawback of a client-side only 
solution in the client-server model – assuming this is the case here – is 
that – rather obviously – it does not work without client-side support.  
There is the NoScript extension, for example, to prevent client-side scripts 
from running, as many people have used client-side scripting for rather 
dubious purposes.

The client-side dialog – in fact, any client-side code – should augment a 
server-side generated solution (to reduce the number of roundtrips to the 
server, thus enhancing user experience and reducing server/network load);
with few exceptions, it should not replace it.  This can be done easily, for 
example:

  <form action="delete-dialog.php"
        onsubmit="return window.confirm('Delete?')">
    <input type="submit" value="Delete">
  </form>

The best solution regarding this approach is a server-side framework which 
provides the classes to generate the forms (here: both for submitting the 
deletion request and confirming it) and the client-side code, so that the 
data only needs to be maintained in one place.
