I've tried this:

on the field. I've tried other actions such as 'mousemove', 'change',
etc., but nothing works. Help!
addEventListener accepts a function as its second argument, which is
called when the event occurs. Instead of *passing* a function, you're
*calling* the function sayhello, and passing sayhello's return value to
addEventListener (which is probably undefined, so clicks, or whatever
event you use, are effectively ignored). Instead try:
elmLink.addEventListener("click", function(){sayhello('world');}, true);
That creates an anonymous function and passes it to addEventListener.
When the element is clicked, the browser calls the anonymous function,
which then calls sayhello.
