This has been discussed a few times. The right way would be to use
event propagation as intended, for example:
<t:removerowlink><span id="confirmRemoval">Remove</span></t:removerowlink>
Then add a handler for the nested element:
Event.observe($('confirmRemoval'), 'click', function(event) {if
(!confirm('are you sure to want to remove?')) event.stop();});
to stop the event from being propagated to the actionlink handler.
Since you are dealing with rows, the problem is with gathering all the
ids of nested elements. If you used a button inside the link instead,
you could just use its onclick handler:
<t:removerowlink><button onclick="javascript:return confirm('blab
la?')">Remove</button></t:removerowlink>
