spacing seems off - should be 2 spaces; see javascript/c++ style guides for more
info.  Should be 1 space after //

Come to think of it, though - why are there any changes to this function?

[Danh Nguyen, 2012/03/08 16:44:19]

I'm not sure how that happened.  I must have messed it up somehow.  Fixed.

arv@chromium.org prefers i++ in JavaScript.

[Dan Beam, 2012/03/07 22:49:45]

Then why'd you write it this way, scr@? :P
http://src.chromium.org/viewvc/chrome/trunk/src/chrome/test/data/webui/ntp4.j...

We do this other places, that's not a big deal.

[Danh Nguyen, 2012/03/08 16:44:19]

Easy fix. :-)  Done.

alignment is off.

[Dan Beam, 2012/03/07 22:49:45]

scr: you might want to explain how it's off

[Sheridan Rawlins, 2012/03/07 23:00:38]

Sho 'nuff.

Please either start a new line after the parenthesis indented 4 spaces -or-
align new lines with the first parameter.

i.e. either
  assertEquals(
      1, selectedTilePage.length,
      'There should be only one selected tile page.');

-or-

  assertEquals(1, selectedTilePage.length,
                      'There should be only one selected tile page.');

I like the latter, personally, if it fits in 80 chars.

null's position.

Please use GEN - print is v8, but node.js uses console.log (in case we ever want
to switch implementations :) )

I changed it to use textContent now.
