Hi,
I used your solution in a method of our javascript rendering engine ( PURE ).

The previous code was bleeding memory on IE.
Not anymore with your solution.

Thanks a lot. I mean a lot.
Cheers,

Vladimir: I have used Drip myself in the past, but to be honest, I'm very skeptical as to how accurate (or even useful for that matter) it is. I've gotten some very strange indications from it, so I take what it tells me with a grain of salt these days.

i'm using drip http://www.outofhanwell.com/ieleak/index.php?title=Main_Page to test yours examples. All of them are leaking in ie7!
It's critical problem for me and my company;-)
My observation.
If i create table row(or cell) with .insertRow(rowindex) no leak, but
vat row=document.createElement('tr');
tbl.appendChild(row) leak!
My problem is i can't add any element like table row(cell), so i have to accept this. Any suggestion?

i'm looking at both test with IE Sieve – http://home.wanadoo.nl/jsrosman/ – and both the leak and no leak demos seem to leak just as much. can anyone verify this?

i'm trying to get to the bottom of my own leaks – feel free to email me.

Oh, good catch! Thanks… I must have goofed when I originally uploaded the scripts. I've corrected this.

I do not however, see the leak in Firefox as you say. Be sure you are testing Firefox in safe-mode with all add-ons disabled. Add-ons like Firebug and Greasemonkey are definitely known to make it look like Firefox itself is leaking, when in fact it is not.

Please correct me if I am wrong, but the scripts on both your 'leak' and 'noleak' pages are identical and hence no difference in performance there.

However I copied, modified and tested locally and it is definitely true. So, thank you very much for the advise as I was experiencing the same problem with my web app and wasn't sure what the problem was.

Moreover, it seems that is not only true for IE it is very much so for Firefox as well.

Maybe the only correct way to use innerHTML LEAK FREE http://www.posos.com/page/Index.cfm?SelNavID=2714. Use outerHTML…
