    Event object

    <html>

    I pulled the following code off the internet. The idea is to intercept
    various user screen events. IOn this case it would just return the x y
    location of the cursor when the mouse is clicked in an alert. It doesn't run
    for me - I get "Event is undefined" error message. What's up?

    <script language="JavaS cript">
    window.captureE vents(Event.CLI CK);
    window.onclick= displayCoords;
    function displayCoords(e ) {
    alert("x: " + e.pageX + " y: " + e.pageY);
    }
    </script>

      I see now that this example only works in navigator. Does anyone know of a
      more generalized function that will account for all browsers? (By "all" I
      mean IE and Netscape 5 or better and those that follow their protocols, I
      don't care if it doesn't work for someone using something totally obscure or
      old and out of date, I'll have a special message saying "bite me" for them.)

          Since I use a browser that you seem to consider "obscure", I am *very*
          tempted to just say "bite me".

          Anyway, try this:
          ---
          <script type="text/javascript">
          if (typeof Event != "undefined" && window.captureE vents) {
          document.captur eEvents(Event.C LICK);
          }
          document.onclic k = function (evt) {
          evt = evt || window.event;
          if (typeof evt.pageX == "number") {
          var pageX = evt.pageX;
          var pageY = evt.pageY;
          } else {
          var root = document.compat Mode == "CSS1Compat " ?
          document.docume ntElement :
          document.body;
          pageX = evt.clientX + root.scrollLeft ;
          pageY = evt.clientY + root.scrollTop;
          }
          alert("x: " + pageX + " y: " + pageY);
          }
          </script>
          ---

              Thanks, I thought I could use events to catch when the mouse was released
              from the scroll bar but that doesn't register. I'm still looking for a way
              to detect that event.

                  Typo?
