Is there a way in JavaScript to listen console events?

Question

I\'m trying to write handler for uncaught exceptions and browser warnings in Javascript. All errors and warnings should be sent to server for later review.

You're going about this backwards. Instead of intercepting when an error is logged, trigger an event as part of the error handling mechanism and log it as one of the event listeners:

try
{
  //might throw an exception
  foo();
}
catch (e)
{
  $(document).trigger('customerror', e);
}

function customErrorHandler(event, ex)
{
  console.error(ex)
}
function customErrorHandler2(event, ex)
{
  $.post(url, ex);
}

_{this code uses jQuery and is oversimplified strictly for use as an example.}
