In the past, I've sent this info back to a CF template which could then process it in
any way needed. Here is the JS code I included with my JS library. Watch out for the
big line wrap on the query_string assignment line!
===START===
var errCount = 0;
function errHandler(msg,url,line) {
if (document.images) {
var par_url = parent.location.href;
if (par_url == location.href) par_url = 'no parent';
query_string =
'http:\/\/www.yoursite.com/JSErrorReport.cfm?url='+escape(location.href)+'&parent='+escape(par_url)+'&referrer='+escape(document.referrer)+'&browser='+escape(navigator.appName+'
'+navigator.appVersion)+'&msg='+escape(msg)+'&line='+escape(line)+'&count='+(++errCount);
var reporter = new Image();
reporter.src = query_string;
}
return true;
}
window.onerror = errHandler;
===END===
The JSErrorReport.cfm template just captures the URL variables and then you're
set--log them, throw them in a DB or email them to an admin.
