Javascript Error Handling Patterns
What do you want to do with an error once you catch it? Do you just need to log it so you can create the missing function, or are you looking to stop exceptions from breaking your code? –Dan Herbert Jun 4 '09 at 17:00 2 I would like to get the name of the missing function called and based on presence of some string call my own function. Any call to a function with the string 'close' would call my close() for example. I would also like to trap the error at that point. –Bob Jun 4 '09 at 17:06 1 exceptionsjs.com provides this functionality and can be taylored to only catch errors related to undefined functionality with its "guard" functionality. –Steven Wexler Aug 4 '14 at 2:48 add a comment| 9 Answers 9 active oldest votes up vote 126 down vote accepted Does this help you: I'm not sure how it handles Flash errors though...

The JavaScript Error Handling: Why You http://www.htmlgoodies.com/html5/javascript/browser-specific-error-catching-in-javascript.html Need it article outlined some of the major reasons why you need to consider error handling sooner rather than later in a Web application's development cycle. Everyone knows that error handling is important, but to what end? In fact, error handling plays many roles, from reassuring the end-users, to helping identify trouble spots in an application, to siphoning off potential security holes in the code. In this installment on error handling in JavaScript, we'll be taking a look at how to code your exception handling in JavaScript in a way that takes browser discrepancies into account. Anatomy of the Try/Catch Block In all browsers, the mechanism of choice for trapping errors is the Try/Catch block. As the name suggest, the Try/Catch Block is made up of two sections. The try {} encloses code in which to trap exceptions; the catch {} section contains code to deal with the error: try { eval("var " + varName + "=" document.inputForm.txtVal); } catch (e) { console.log("An exception occurred in the script."); } It all seems so easy. However, there is a glitch in the above c

Introduction Error handling? It seems like almost anything can happen in the user's browser, for example: Bug in an obscure browser JavaScript selectively blocked by a corporate firewall Third-party data feed goes down unexpectedly Coding mistake that got through testing To catch these runtime errors, most would suggest setting window.onerror to an error handling and/or reporting function, though there are issues with this approach: While browser support for window.onerror is good (Firefox, Internet Explorer, Chrome 10+, Safari 5.1+, iOS 5+), it is not perfect. Most notably, window.onerror isn't supported in Opera and older WebKit-based browsers. A window.onerror handler does not have access to the Error object. Some browsers (Firefox, Chrome, O
you when something goes wrong. On the other, it won’t give you enough information to actually debug the problem. Notably absent in many cases is the stack trace. That said, with a little bit of work it’s possible to get stacktraces that are reasonably complete in all browsers. Bugsnag’s JavaScript error monitoring uses the techniques below, ordered by effectiveness. The Good Modern Chrome and Opera (i.e. anything based around the Blink rendering engine) fully support the HTML 5 draft spec for ErrorEvent and window.onerror. In both of these browsers you can either use window.onerror, or (amazingly!) bind to the ‘error’ event properly: // Only Chrome & Opera pass the error object. window.onerror = function (message, file, line, col, error) { console.log(message, "from", error.stack); }; // Only Chrome & Opera have an error attribute on the event. window.addEventListener("error", function (e) { console.log(e.error.message, "from",
