Small helper script (e.g. for Chrome Snippets) to throw a Browser Notification when a .error occurs

check_error_notification.js

Notification.requestPermission().then(function(result) {
    function checkError() {
        console.log('check error');
        if (jQuery('.error').length > 0) {
            new Notification("Batch error occured");
        }
        else {
            setTimeout(checkError, 10000);
        }
    }
    checkError();
});
