How to simulate a click with JavaScript?

Question

I\'m just wondering how I can use JavaScript to simulate a click on an element.

Currently I have:

Answer 1

Here's what I cooked up. It's pretty simple, but it works:

function eventFire(el, etype){
  if (el.fireEvent) {
    el.fireEvent('on' + etype);
  } else {
    var evObj = document.createEvent('Events');
    evObj.initEvent(etype, true, false);
    el.dispatchEvent(evObj);
  }
}

Usage:

eventFire(document.getElementById('mytest1'), 'click');
