when you click on the text only one click event is created and it
bubbles up through the dom. So it first is triggered on the span and
then bubbles up to the a and so on. You need to actually cancel the
event if you want it to stop bubbling. In prototype you can use the
Event.stop() function.
<a href="#" id="link"><span id="linkSpan">Observed</span></a>
<script>
$('link').observe("click", function(e) {alert("You clicked a link!");});
$('linkSpan').observe("click", function(e) { if ( confirm('stop span
click event?') ) { Event.stop(e); return false; }});
</script>
Hope that helps!
