Catch javascript errors

[Mihai Ciureanu]

Hello.

I've been struggling to fin a method to catch javascript errors in the C# host application. Any idea how to do that?

Thank you.

Hi Mihai,

In CEF there is the OnUncaughtException callback that can handle v8 exceptions globally.

Or you can use pure javascript to catch errors using window.onerror event:

window.onerror = function (errorMessage, url, lineNumber) {}

Though, this one won't provide you stack trace. Also CEF v8 stack trace is lost when called from within onerror.

Best regards,

Czarek

Thank you. I'm trying to do the same as I would do for a normal desktop application. In case of any unhandled exception show some message, log it, etc...  The errors that I encounter from time to time are either javascript errors or some browser errors - something happens to application cache, etc... (I use html5 application cache). I'll try with OnUncoughtException, thank you.
