A couple of things:
- If you see Wiki spam, please help us all by backing out until the
real page reappears.
- If you ask a loosely formed question of Google, you can expect to
be awash with random hits. Let's say the problem you were trying to
solve was "hmmmm, I want to replace something on the page and I
forget the exact function name." Typing "rails rjs replace" provides
a number of great hits right up top. Just narrowing the search makes
a world of difference.
Give it a try.
