Answer 1

You could try this:

var lnk = document.getElementById('lnk1'); // don't forget var!

var oldHandler = lnk.onclick;
lnk.onclick = function(ev) {
  if (oldHandler) oldHandler(ev);
  // do something ...
};

That code saves a reference to the old handler, and if it's not empty it calls it before doing whatever else the new handler wants to do.

You could put the call to the old handler after the new code, or mixed in, or whatever.
