Error handling

Question

I tried using window.onerror and window.addEventListener("error", ...), in order to handle some JavaScript errors, but it didn't seem to work in my JavaScript Metro style app :/

I can create a wwa-error.html page, to handle navigation errors. But is there a mechanism to catch other exceptions globally?

Thanks.

Hello,

You can use try-catch block to handle the error message. Please follow this thread.

I tried this out just now on the Consumer Preview release and my error handler appears to be called for the common cases I can think of (user thrown exceptions, reference errors, syntax errors.) Do you have specific code that is not causing window.onerror to be called?
