Question

I’m using ELMAH to log my .net errors. It’s working great, but I want to extend the error logging to include client side errors, i.e arbitrary JavaScript errors. I can capture the errors using window.onerror event and then call a .net handler (.ashx) to log the error in elmah, but this is just my little hack to solve the problem. Is there a better way to log client side error to elmah?

Answer 1

Catch all javascript errors by handling the window.onerror event and make ajax call to manually log error in elmah

window.onerror = function (msg, url, linenumber) {  

 //make ajax call with all error details and log error directly into the elmah database

 //show freindly error msg here to user

 //hide error from browser
 return true; 
}

No better solution was found at the time.
