function trackJavaScriptError(e) { | |
var errMsg = e.message; | |
var errSrc = e.filename + ': ' + e.lineno; | |
ga('send', 'event', 'JavaScript Error', errMsg, errSrc, { 'nonInteraction': 1 }); | |
} | |
window.addEventListener('error', trackJavaScriptError, false); |
Universal Analytics have exception tracking support: https://developers.google.com/analytics/devguides/collection/analyticsjs/exceptions
So the code should look like this:
function trackJavaScriptError(e) {
var ie = window.event || {},
errMsg = e.message || ie.errorMessage;
var errSrc = (e.filename || ie.errorUrl) + ': ' + (e.lineno || ie.errorLine);
ga('send', 'exception', {
'exDescription': errSrc + ': ' + errMsg,
'exFatal': false
});
}

If an error comes from a different domain, you don't have e.filename. So your script is accessing ie.filename. If you have a firefox, it's crashing, because ie is not defined. I changed the second line of your script. Now it's working correctly with errors from different domains.
