limits and how they present themselves. I started out by discussing the long-running script dialog and then moved on to other performance issues. I thought I had covered most of the annoying and ill-explained JavaScript limits, but this past week I ran stack overflow in javascript across another that is worth discussing: stack overflow errors. I've written about how too much javascript recursion stack overflow recursion can lead to performance issues. Most browsers have limits on how much recursion is allowed before the script is automatically canceled. This javascript call stack size is a limit that is separate from the one determining if the script is long-running. And the limit is really less about recursive calls so much as it is about the size of the JavaScript call stack. Not

surprisingly, different browsers have different call stack sizes. Also not surprisingly, the method that they use to determine the call stack varies as well. The various call stack sizes I could measure are (give or take, might be off by 1 or 2): Internet Explorer 7: 1,789 Firefox 3: 3,000 Chrome 1: 21,837 Opera 9.62: 10,000 Safari 3.2: 500 Some have said, but I cannot confirm, that IE and Opera's call stack size are somewhat tied to ie8 stack overflow at line 0 the amount of RAM on the system. All other browsers have this set by a default. It's also worth noting that WebKit seems to have a much higher limit and that Safari imposes a stricter limit on the JavaScript engine. There are two common scenarios in which this limit could be reached. The first is simple recursion, such as: function recurse(){ recurse(); } recurse(); The second is a more devious and harder-to-identify issue, especially in large code bases, where two functions each call the other, such as: function doSomething(){ doSomethingElse(); } function doSomethingElse(){ doSomething(); } doSomething(); In each case, the browser will end up stopping your code and (hopefully) display a message about the issue: Internet Explorer 7: "Stack overflow at line x" Firefox 3:"Too much recursion" Chrome 1: n/a Opera 9.62: "Abort (control stack overflow)" Safari 3.2:"RangeError: Maximum call stack size exceeded." Chrome is the only browser that doesn't display a message indicating the problem. If you see any of these error messages pop up, it means one of the two patterns are involved and need to be changed. There's usually a line number and file name associated with this error, so it's fairly straightforward to debug. Perhaps the most interesting part of stack overflow errors is that they are actual JavaScript errors in some browsers, and can therefore be trapped using a try-catch statement. The excepti

The problem is quite clearly http://stackoverflow.com/questions/226102/stack-overflow-in-line-0-on-internet-explorer not in line 0, but somewhere in the list of stuff that I'm writing to the document. Everything works fine in Firefox, so I don't have the delights of Firebug and friends to assist in troubleshooting. Are there any standard causes for this? I'm guessing this is probably an Internet Explorer 7 bug or something quite obscure, and my Google-fu is bringing me little joy currently. I can find lots of people who have run into this before, but I can't seem to find how they solved it. javascript internet-explorer error-handling share|improve this question edited Mar 17 at 18:23 danday74 2,67411241 asked Oct 22 '08 at 14:55 glenatron 7,45374686 28 sick that this has 10k views. –Sneakyness Dec 23 '09 at 17:24 It's a really common and generic error message- it can show up for a whole lot of reasons and it totally doesn't explain itself.

When i run the application in Tnternet explorer I http://www.cappuccino-project.org/blog/2010/03/internet-explorer-global-variables-and-stack-overflows.html get an error "Stack Overflow at line:0" constantly. Can anybody explain me why we get this error and a solution for this. I even tried by turning off the "Disable script Debugging" in stack overflow internent options. But still there is no change. Thanks in advance Regards, Janu Eric Pascarello author Rancher Posts: 15385 6 posted 6 years ago Your magical Code is? Eric Jahnavi Kondapaneni Ranch Hand Posts: 56 posted 6 years ago hi, Here is the code snippet. function open( ) { window.open (url,'height=200,width=300'); }; I am calling this javascript code from Flex using the below code ExternalInterface.call("open"); call stack size Eric Pascarello author Rancher Posts: 15385 6 posted 6 years ago LOL... You created a circular reference. When you declare functions in global scope [as you did], you can call them via window.functionName(). so the following code function hey(){ //code } can be called via hey(); or window.hey(); along with countless other ways. You just overwritten the window.open function so your code keeps calling itself. Rename your function to something else. Eric Jahnavi Kondapaneni Ranch Hand Posts: 56 posted 6 years ago Oh thanks!

you pull your hair out for days. A bug that almost certainly includes Internet Explorer. This was one of those bugs for me, and since I haven’t found a lot of information out there even now that I know what the problem was, I wanted to write it up for posterity. It starts with what looks like a relatively benign function, that we’ll call recurse: window.recurse = function(times) { if (times !== 0) recurse(times - 1); } recurse(13); If you pass in the magic number 13 (or anything higher), this recursion is going to fail with our stack overflow pop up. No problem, you say? You’ve fought Internet Explorer before, and you know how to get down to business. Fire up the trusty IE 8 debugger and get to work! Unfortunately for you, the debugger won’t be triggered. Just a pop up for you. If you’re feeling extra ambitious, maybe you’ll try installing Visual Studio and hooking up the advanced debugger directly to IE; I did. No such luck. I should mention that the code above wasn’t what forced me to investigate this bug. I’m not usually in the habit of writing recursive functions that don’t actually do anything. And when your code base is tens of thousands of lines long, and your coworker has pushed a couple thousand new lines of code (which radically alter the load process), tracking down any problem without a debugger starts to get hairy. At one point in the process, I actually stepped line by line through every single new line of code, certain I’d track down the bug. I didn’t, because not only does IE not trigger the normal exception mechanism, it doesn’t even report the error until after any waiting script executions are finished. Fun. Thankfully, my neighbor works at Microsoft, so I was able to get an inside look into the issue. That’s where our test function comes in (thanks Microsoft). Let’s get back to it: var recurse = function(times) { if (times !== 0) recurse(times - 1); } recurse(13); recurse(10000); Our new version works. Can you spot the difference? We’re using a “local” (but really global considering our current scope) variable here, instead of assigning the function to a property on the window object. This tells us that it has something to do with the window “host” object, but it isn’t the whole piece of the puzzle just yet. (function(){ var recurse = function(times) { if (times !== 0) recurse(times
