Hi,
One of the few good things about those old-style handlers is that
they're attributes, so finding the links is easy:
var hookedlinks = $$('a[onclick]');
Then if your goal is to remove the handler:
var n;
for (n = hookedlinks.length - 1; n >= 0; --n) {
hookedlinks[n].onclick = null;
}
Or you can have more fun, I wrote this up a while back to convert DOM0
handlers into modern ones and optionally put some pre-condition logic
in place prior to firing the DOM0 handler:
* * * * (also at http://pastie.org/573599)
function wrapDom0Handler(elm, evtname) {
var propname, dom0handler;
// Grab the current DOM0 handler for the event
propname = "on" + evtname;
dom0handler = elm[propname];
// Clear it
elm[propname] = null;
// Hook up your handler
elm.observe(evtname, function(event) {
var rv;
alert("TODO: Your optional precondition logic goes here");
// Chain to the DOM0 handler, if any
if (Object.isString(dom0handler)) {
rv = eval(dom0handler);
}
else if (Object.isFunction(dom0handler)) {
rv = dom0handler.call(elm, event);
}
if (!Object.isUndefined(rv) && !rv) {
// Handler returned something falsey, cancel
event.stop();
}
});
}
* * * *
HTH,
