How to create/trigger event in Javascript?

Question

How do i create and pass the event to event handler?

Basically i want to fire an event called key down on focus of text input box how do i do that?

Perhaps firing keydown isn't what you want - it won't cause a letter to be inserted. — David Tang

This probably blog entry should help you.

<input type="text" onchange="alert('i was clicked')" id="test">
<script>
    document.getElementById("test").onchange()
</script>

Use this if you actually want to trigger the event programmatically:

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);
  }
}

Here is what i found which meets my requirement using Jquery.

$('#inputText').focus(function() {
         $('#inputText').trigger({type:'keyup',keyCode:'40'});
    }
