IE bug: Add Comment

Question

When I click the Add Comment button, it sometimes doesn't appear to do anything, but internally the comment has been added. When I click it again, I get a message that states, "it appears this is a duplicate" and the screen refreshes.

Happens in IE8 and IE9.

Comments

It's a JavaScript error in this code:

n.replace.call(f.slice(e.index),a,function(){for(var c=1;c<arguments.length-2;c++)if(arguments[c]===undefined)e[c]=undefined})

The problem is that f.slice() is undefined.

This is with Question2Answer installed alongside WordPress 3.3.1. I tried it with both the Default theme and the Candy theme (same results).

I get something similar in any browser, because there is a delay between clicking the button and the comment getting added, with no indication it's doing something.

---

If I remove lines 395-398 from qa-include/qa-page-question.php, the JavaScript error goes away, but I still get the bad behavior in the original post.

---

I belive I have the same problem as DisgruntledGoat, with a long delay (> 10 sec). I do not have WordPress installed, and the problem appears in both IE and Chrome (not tested other browsers).

---

Where is this code that begins n.replace.call(...) - in which Javascript file?

---

I believe it's in jQuery code. The problem is that "f" in f.slice(...) is an integer.  Since it's obfuscated, I don't know how to find the code.

---

OK, that makes sense. Please try substituting the latest jQuery version in qa-content (rename it the old jquery-1.7.1.min.js file name for now) and seeing if that fixes the problem, then please let me know.

---

Updating to jquery 1.7.2 eliminates the bad behavior in the original post.  It does not solve the f.slice() problem.  If I comment out lines 395-398 in qa-page-question.php, Question2Answer works for me.

I'm afraid I can't reproduce this here with IE8. Can you post a link to your own site, along with the extra steps to reproduce, so I can take a look there?

---

Sorry, our site is behind a firewall. I'll see what else I can do.

@gidgreen we're seeing the same issue, but with IE 9.  Have not tested with IE 8 yet.  We are also behind a firewall, I'm afraid.  I do think the f.slice error appears when I try to post a comment with too short a length.  The Jquery error pops in the status bar but Question2Answer still appears to run and presents you with the error message about your post being too short.

---

Is this problem still happening on this site? I'm don't seem able to reproduce it. This may be because jQuery has been updated to 1.7.2.

I have not seen either error since upgrading to the latest JQuery (at the time, 1.7.2).
