Why not just |.addEventListener("click", openOptions, false);|?

[Thomas Greiner, 2013/12/03 12:06:05]

I try to avoid passing event parameters on to external functions that are not
solely used as event listeners. Might be an unnecessary optimization, though, so
I changed it now.

[Wladimir Palant, 2013/12/03 12:55:43]

Actually correct here - otherwise the event will be passed as callback parameter
and cause an exception.

[Thomas Greiner, 2013/12/04 10:44:50]

Done.

[Felix Dahlke, 2013/12/02 15:45:58]

Nit: Wouldn't hurt to assign collapsers[i] to a temp here, since it's used a
lot.

[Thomas Greiner, 2013/12/03 12:06:05]

Done.

[Wladimir Palant, 2013/12/03 12:55:43]

Better solution - add toggleCollapse as callback without binding it to a
particular node, use event.currentTarget to get the node.

Also, any particular reason why the last parameter isn't false?

[Thomas Greiner, 2013/12/04 10:44:50]

Done.
No, not anymore.

[Wladimir Palant, 2013/12/03 12:55:43]

Isn't the logic reversed here? I think it should be collapsed if the pref is
false - at least the way that pref is called right now.

[Thomas Greiner, 2013/12/04 10:44:50]

Done.

classList.toggle() returns the new value - no need to check the value and toggle
separately. How about:

var disabled = enabledButton.classList.toggle("off");
if (disabled)
  ...
else
  ...

The parameter is unused, might as well get rid of it.

Done.

[Wladimir Palant, 2013/12/03 12:55:43]

As I said, it's better to use that parameter and replace this by
event.currentTarget. Btw, the canonical name for that parameter is event.
