You can execute custom JavaScript to hook into window.onerror.

You can tell your JavaScript to return your data back to Selenium, but because you are asking about errors, I suggest not doing that. Depending on the error, the error could break JavaScript and might prevent it from returning.

A more robust way might be to create a server exposing a handler to the web, to request from your JS.

So your JS to execute from Selenium (before the errors occur) might look like this:

window.onerror = function(message, file, line) {
    var asyncHR = new XMLHttpRequest();
    var URL = "https://www.yourserver.com/errorlogger?file=" + file + "&line=" + line + "&message=" + message;
    asyncHR.open("GET", URL, true);
    asyncHR.send(); 
};

And from there, let the server take care of the logging - write to file, DB, etc...
