How to detect browser internal JavaScript errors?

366 Views Asked by Simon Ferndriger At 06 April 2025 at 06:11

We are currently logging all JavaScript errors. However, some errors seem to be browser internal (plugin, etc) related. Like this one:

Error: Error calling method on NPObject!

Line: 0

Script: http://www.lookr.com/lookout/1329030315-Giglio-Porto

How is it possible to ignore those browser internal, non-directly-website-related errors?

Ignoring all errors with line 0 also seems not appropriate, since inline JavaScript errors would also be ignored (which is not desired)

Thank you in advance for your suggestions.

This is the closest that you can get (onerror)

<html>
<body>
    <script>
        window.onerror = function(e) {
            alert('Error');
            console.log(e);
        }
        show('Error'); // show is not defined
    </script>
</body>
</html>
