Can anyone point me to some code that will display messages, in a seperate
window, from javascipt. ie effectively a trace window?
TIA

Thanks v much, works a treat
one oddity though
in Opera 7.51 all OK
in IE 6 I had to alter the following
//startDebug.newWindow = window.open("",debugWindowName,
"scrollbars=yes,resizable=yes,width=700,height=500");
startDebug.newWindow = window.open("",null,
"scrollbars=yes,resizable=yes,width=700,height=500");
as it was throwing the following error
---------------------------
Error
---------------------------
A Runtime Error has occurred.
Do you wish to Debug?
Line: 15
Error: Invalid argument.
---------------------------
Yes No
---------------------------
Again my thanks
Chris

Glad to have helped out.
I suspect you had a special character in your file name. I am using
the filename as the debug window name. Web browsers seem to take the
input file name and use the escape function on them. For instance,
the space character in a file name is converted to %20. The IE
version of window.opend doesn't accept a % as part of the debug window
name.
I have posted a new version of the file below. I filter out the % and
all the other special characters.
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">

// You need to have enabled popup windows
function startDebug(debugMode) {
startDebug.debugMode = debugMode;
if (startDebug.debugMode == true) {
var debugWindowName =
document.URL.substr(document.URL.lastIndexOf("/")+1);
var thePosition = debugWindowName.indexOf(".");
if (thePosition > 0)
{ debugWindowName = debugWindowName.substr(0,thePosition); }
// Get rid of special characters because IE won't accept them
debugWindowName =
debugWindowName.match(/[a-zA-Z0-9]/g).join("");
try
{ startDebug.newWindow = window.open("",debugWindowName,
"scrollbars=yes,resizable=yes,width=700,height=500"); }
catch(e)
{ debugWindowName = "debug";
startDebug.newWindow = window.open("",debugWindowName); }
startDebug.newWindow.document.writeln(

Opening and then writing into a window is unreliable.
It's much safer to have the new window load the content when it's ready.
function log(msg) {
globalHTML="<html><body><p>"+msg+"</p></body></html>";
window.open("javascript
pener.globalHTML",
"logWindow",
"width=400,height=200,resizable").focus();
}
Since the window opens immediately, there's really no point in displaying the
date.

How can you get this to autoscroll to the trace line just entered?
