Any event handler is always passed a special
event object that represents the event that fired to trigger this function. You can use
it to access information about the event, such as which element was the target
(event.target), the location of the mouse (event.clientX and event.clientY), etc.
FOR EXAMPLE: Following page has button - which when clicked alerts user with
pageX & pageY position. NOW, replace the script (alert within function that is bold
and italic) to display the the input tag value = "Click Here" using single line of code
(within alert box).

...
<script>document.getElementByld("testbutton").onclick = function(event) {
alert(event.pageX+","+event.pageY);
