Join ajax error handling javascript them; it only takes a minute: Sign up Exception line-number in Jscript-ASP up vote 2 down vote favorite I'm developing a website with server-side JScript engine over ASP server. I have several try-catch clauses in my code looking roughly like http://www.w3schools.com/js/js_errors.asp this: try { // do something } catch (err) { // pass it to the frontend code die("Exception caught: " + err.description); } I would very much like to display the line number in which the error occurred. The filename would be a nice bonus but it's not very important. How can it be done?

The JScript exception object does not contain enough info either. Been down this route, unfortunately there is no way to get the error details you want. –Pete Duncanson Dec 2 '09 at 8:39 add a comment| Your Answer draft saved draft discarded Sign up or log in Sign up using Google Sign up using Facebook Sign up using Email and Password Post as a guest Name Email Post as a guest Name Email discard By posting your answer, you agree to the privacy policy and terms of service.

2009 - 15 comment(S) 52,429 views RATE IT (Rated 4 by 44 people) Like the Object oriented programming the exception handling is also not used while coding in JavaScript. That why in most of cases http://www.dailycoding.com/posts/javascript_exception_handling_techniques.aspx if there is any problem in one part in a page then surprisingly other part also stops working. In this post we will be discussing the various techniques to handle exceptions in JavaScript. Using try..catch block try..catch block in JavaScript is very much similar to the regular C# try..catch block. The suspected code will be put in try block and all exceptions which will occur in the error handling try block will be caught in catch block. window.onload = function() { try { var x = 90; var value = x / y; } catch(err) { document.write(err.name + ": " + err.message + "
"); } } Output: TypeError: 'y' is undefined In catch you will get the object containing type and description of the exception. More over you can also use finally block in the javascript error handling same way as you use in C#. window.onload = function() { try { var x = 90; var value = x / y; } catch(err) { document.write(err.name + ": " + err.message + "
"); } finally { alert('This is finally block'); } } Using onerror event onerror event will be raised each time there is any error while performing a action in the document. This like on place exception handling similar to Application_Error in ASP.NET. Here is sample code which demonstrate this: window.onload = function() { var x = 90; var value = x / y; } window.onerror = function(errorMeaage, fileName, lineNumber) { document.write('Error: ' + errorMeaage); } Using jQuery Solution It is similar to using onerror but with jQuery syntax. The syntax is: $(window).error( function(errorMeaage, fileName, lineNumber) { // handle error here } ); Javascript jQuery 15 comment(S) very cool & good tip, thank you very on Aug 5, 2009 12:54 AM very cool & good tip, thank you very much for sharing.Can I share this snippet on my JavaScript library?Awaiting your response.
