Hi,
Closures is something that (can) cause memory leaks, right?
kangax, would you mind explaining in a bit more detail why you wrote the
code like you wrote it? I'm a bit lost in it. I restructured the code you
wrote a bit... http://pastie.caboo.se/156248
- Is there a reason why you don't write a ';' after the new Ajax.Request
(...)?
- Is there a reason why you don't write a ';' after the
someArray.each(function(item)
{ ... })?
- I'm getting lost in how you constructed the onSuccess callback...
Thx...
Manu.
