Is it possible to get notified for every error logged in the console using JavaScript? -

i know can register callback javascript errors, this:

window.onerror = function(message, url, line) {     // ... }; 

however, i'd notified of other error that's being logged console, such images couldn't loaded (http status code 404) or other http request bad status code such 500.

is possible, , if yes, how? note intend use debugging purposes, doesn't matter if solution works in chrome.

it possible intercept calls console.log, javascript's flexibility :

var oldconsolelog = console.log;  console.log = function (x) {     oldconsolelog.call(console, x);     alert(' message printed console ' + x) ; } 

obviously, alerting annoying, can change alert whatever callback or event raising of like.
