you, helping each other. Join them; it only takes a minute: Sign up Line and column in Javascript Error event attributes up vote 3 down vote favorite I've decided that there are some errors which I don't https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Error/lineNumber want to go to the browser error handler. But I still want to know about them. In my actual code I have a function which stores the errors in a hidden element and ajax submits them to a database. Following is a simplified version of my try block: try { newValueEvaled = eval(newValue); }catch(err) { alert("Error caught: Line " + err.lineNumber + ((err.columnNumber != undefined)?', Column:' + err.columnNumber:"") + '\n' + err.message); } I'd like http://stackoverflow.com/questions/5902416/line-and-column-in-javascript-error-event-attributes the columnNumber too. Currently it is never there, but somehow the browser error console has access to it. Can anyone tell me how I can get access to it as well? javascript script-debugging share|improve this question asked May 5 '11 at 18:23 Luke 345112 Erm, why do you want to do this? The error going to the browser allows the native browser, WebDeveloper extension, FireBug extension to show you the same information... often with more info, and without blocking the script. .lineNumber is a Firefox only extension btw. –Rudu May 5 '11 at 18:34 @Rudu The idea is to produce a log of all javascript errors via a simple ajax request. Errors logs are only helpful if they are specific, so including data like this is the whole point. –Luke May 26 '11 at 21:50 add a comment| 2 Answers 2 active oldest votes up vote 3 down vote accepted I'm almost certain it's not possible to get the error column number from JavaScript running in the page. Firebug/WebKit console/IE console has access to internal browser objects that provide more information about the call stack than is available to code running inside the page. share|improve this answer edited May 5 '11 at 23:16 answered May 5 '11 at 18:42 Tim Down 193k42309393 According to the Mozilla Docuentation (developer.mozilla.org/en/JavaScript/Reference/Global_Obje

Whenever there is a javascript error on the page, shown in the status bar of the IE browser, the line number reported to contain the error, does line number not match with the line number that actually contains the error. I am doing a right click>view source to find the line number reported. But that line does not contain the error. The error, I assume, is in some other line. What could be the reason for the erroneous line numbers being reported.

Also, i used to get the correct line numbers say about a month ago.I dont know how all of a sudden there is this frustrating discrepancy. –The Machine Jan 6 '10 at 9:13 1 In addition to the great suggestions about using the IE dev tool in IE > 8, you can also get Firebug Lite, which works in any browser, so Firebug can actually be of help :) –Kato Feb 1 '12 at 23:04 add a comment| 5 Answers 5 active oldest votes up vote 7 down vote As noted in other answers, IE is bad at reporting line numbers for errors. 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.

P: n/a Kim Haines I need help finding where an error is occuring in my code. I use a try-catch block like this in my global.asa: try { //my code } catch (e) { Application('errormsg') = ("An exception occurred in the script. Error name: " + e.name + ". Error description: " + e.description + ". Error number: " + e.number + ". Error message: " + e.message); } And this is what is SOMETIMES returned when I display Application('errormsg'), the rest of the time, it works: An exception occurred in the script. Error name: Error. Error description: Path not found. Error number: -2146828212. Error message: Path not found But I don't know which path is not found! (I'm using the filesystem object and importing data from a file into SQL.) Is there a way to display the line number of the error or more details? Or do I just have to try to catch the error by going through each bit of code? Jul 20 '05 #1 Post Reply Share this Question 3 Replies P: n/a Janwillem Borleffs "Kim Haines"
