However, the built-in debugger (press F12) in IE8 and later is much more helpful, so I suggest you try that. share|improve this answer edited Jun 25 '13 at 13:49 answered Jan 6 '10 at 9:17 Tim Down 193k42309393 I agree. "Tools -> Developer Tools" is what you want instead of "View Source" Also if you change your internet options to stop/prompt on javascript errors, it usually comes up with a "do you want to debug?" button which takes you straight in to the dev tools –Graza Jan 6 '10 at 11:47 add a comment| up vote 4 down vote accepted I found the problem after a lot of trials. Hopefully, this will be of use to some guys facing this frustrating problem. RightClick>View Source is the code what the browser sees to render the page. However, that is not all. The page could also have other HTTP requests to css ans js f

It doesn't even say what file, but I've looked at my main javascript file, viewing the page source, etc. This has happened to me before and I've looked around until I finally find an error with the code -- usually a comma -- but I would really like to http://stackoverflow.com/questions/1506593/need-to-find-actual-location-of-line-char-in-internet-explorer-script-errors get some use out of these line/char numbers. I read once that it's a reference to the internal version of the page that IE reads from.

If you're including multiple javascript files and all it gives you is a line # and char # it's alot of work to concatenate all the scripts together to figure it out where the error is. If I can find the error in firefox using firebug then that's the easiest way. If it's an IE only problem what I do is enable script debugging in Internet Options, Go to Tools->Internet Options…->Advanced->Disable Script Debugging (Internet Explorer) Go to Tools->Internet Options…->Advanced->Disable Script Debugging (Other) then attach Visual Studio Debugger when an error occurs. If you're using IE 8, install the developer toolbar because it has a built in debugger. If you are really keen on n

The JavaScript Error Handling: Why You 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 error line number 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 code; Internet Explorer doesn't recognize the console object. The alternative of using the fully supported alert box is tempting, but don't do it! The whole point of catching errors in the first place is to get rid of those annoying popups that appear every time an error fires. Instead, consider writing error messages to a designated part of the page or, in the case of validation errors, you can display the m
the new WordPress Code Reference! Using Your Browser to Diagnose JavaScript Errors If you're experiencing issues with your interactive functionality this may be due to JavaScript errors or conflicts. For example, your flyout menus may be broken, your metaboxes don't drag, or your add media buttons aren't working. In order to formulate your support request it helps the team to know what the JavaScript error is. This guide will show you how to diagnose JavaScript issues in different browsers. Contents 1 Step 1: Try Another Browser 2 Step 2: Enable SCRIPT_DEBUG 3 Step 3: Diagnosis 3.1 Firefox 3.2 Internet Explorer 3.3 Chrome 3.4 Safari 3.5 Opera 4 Step 4: Reporting Step 1: Try Another Browser To make sure that this is a JavaScript error, and not a browser error, first of all try opening your site in another browser. if the site is not having the same issue in the new browser you know that the error is browser specific if the site is having the same error it is not an error that is specific to one browser Make note of any browsers you are experiencing the error in. You can use this information when you are making a support request. Step 2: Enable SCRIPT_DEBUG You need to turn on script debugging. Open wp-config.php and add the following line before "That's all, stop editing! Happy blogging". define('SCRIPT_DEBUG', true); Check to see if you are still having an issue. Issue is fixed - turn off script debugging and report the issue on the support forum, telling the volunteers that you turned on script debugging and it solved the problem. Issue persists - proceed to Step 3. Step 3: Diagnosis Now that you know which browsers you are experiencing issues in you can start to diagnose the issue. Firefox 1. Open the Console Go to the screen where you are experiencing the error. In Firefox, navigate to Tools > Web Developer > Error Console or press Ctrl + Shift + J. 2. Identify the Error The error console will open. If you don't see any errors try reloading the page. The error may be generated when the page loads. The console will provide you with the error type, the location of the error and the line number The image above shows the error to be in jquery.js on line 2. Internet Explorer Bear in mind, IE behaves vastly differently from other browsers when it comes to JS errors, and reports on them in disparate ways. The first thing to check when facing a problem in IE is if the problem only exists in IE. Also note that the debugg
