window.onerror not working in chrome
window.onerror is not triggered when the console directly generates an error. It can be triggered via setTimeout though, e.g., setTimeout(function() { notThere(); }, 0);

The window.onerror works in Chrome (see jsfiddle - http://jsfiddle.net/PWSDF/), but apparently not in the console - which makes some sense.
Some other reasons that you may not be able to handle errors in window.onerror (apart from the mentioned ones):
- Another library sets
window.onerrorafter you. If you are using Angular, errors wont pass through
window.onerror. You have to handle them using this factory:.factory('$exceptionHandler', function() { return function errorCatcherHandler(exception, cause) { console.error(exception); if (window.OnClientError) window.OnClientError(exception); }; })
