[Javascript] Event Capture

Fri Mar 23 07:37:38 CST 2001

One of the best investments I've made, IMHO, is "Pure JavaScript" by Wyke,
Gilliam, and Ting ISBN:0-672-31547-5 if for nothing else the Appendices that
show the functions supported by various versions of Netscape, Internet
Explorer, Opera, and ECMAScript support.

Subject: [Javascript] Event Capture

Similar problem to my other posts. I need to capture events for different
Browsers. To capture a mouse move for example, can I use this method for all
3 Browser formats? How do I capture the scroll position for NN6/IE5 ?

<SCRIPT>
function mouseMove(evt) { // NN6, IE5, Opera 5
  if(document.getElementById) {
    cmx = evt.getClientX();
    cmy = evt.getClientY();
  }
  else if(document.all) { // IE4
    cmx = evt.clientX + document.body.scrollLeft;
    cmy = evt.clientY + document.body.scrollTop;
  }
  else if(document.layers) { // NN4
    cmx = evt.pageX + window.pageXOffset;
    cmy = evt.pageY + window.pageYOffset;
  }
}
</SCRIPT>

Thanks
