I''m trying to understand Javascript in Rails.
I have a controller called logo. In there I have a method called new. In
views I have a folder called logo, with logo.rthml in layouts with
<%javascript_include_tag :defaults %> in that same file. I have a file
called new.rhtml in the folder logo. In the same folder, logo, I have a
new.rjs. Is that the right setup? I can''t get this to work:
page.alert("hello")

Can Rails actually deal with Javascript? I can''t get it working. Very frustrating. Shouldn''t the above setup be correct?

Problem #1: You''re assuming that Rails does Javascript. Javascript can only be run by a browser, Rails just has lots of helpers for printing out useful Javascript to the page. Problem #2: What exactly are you trying to do? RJS is mostly used with AJAX calls (aka you are creating script that gets executed when Ajax.request is called). And actually, the documentation doesn''t "really suck", you''re trying to use a feature without understanding how or what it does.

If you're looking for documentation about Prototype's methods then of _course_ the Rails docs are gonna suck. BTW, there's no documentation about CSS selectors, or HTML frames, or JS function definitions either. :/ I guess Rails sucks because it isn't a one-stop shop for all your web application needs like PHP is. :/ </sarcasm> RSL On 3/15/07, Pål Bergström <rails-mailing-list@andreas-s.net> wrote:> > > Jason Roelofs wrote: > > On 3/14/07, Pål Bergström <rails-mailing-list@andreas-s.net> wrote: > >> for Rails to be inspired by.

But Rails as a framework has been the most > difficult.I see your point, but for sake of argument, our side of the story is that Rails is built to make web programming easier, not design. Rails is built to take care of the crap that goes into most web programming (propagated mostly by PHP) and to make the process enjoyable. Rails assumes that you know HTML, that you know web technologies and that you know the basics of programming itself. It is not a part of Rails, nor should it be, to offer tutorials or information on Javascript, as there is plenty of that on the web already. The documentation is sufficient in explaining what the Javascript helpers give you, even to the point of sending you off to Script.taculo.us for the documentation of the Javascript library itself. As a library developer''s point of view, if one had to package up documentation for every bit and piece used in the library, it would be an ungodly huge bloat of documentation text that would quickly be out of date and littering the web with bad copies of said documentation, making everyone''s lives more difficult. Rails is a change in web development thinking. For someone who''s been with PHP for a long time, it''s understandable if they have a hard time switching, but the time spent is more than worth it. Again, we are more than happy to answer specific questions about Rails. If you want to know how certain other parts work (Javascript, etc), we can help by pointing you to good documentation. That''s pretty much the developer''s side of the story.

BTW you would hide the "layer" (or do you mean div) like this
<%=link_to_function("Hide my Layer", nil , :onclick =>
"Element.hide(''layer1'')" )%>

Now that I know where to look. My original question was different. I basically was trying to do an alert() onload, or onparse. That I haven''t figured out yet. Layer is an old and common way of describing a div, yes.

Though technically if you''re using Prototype, you can simply do:
Element.hide(''layer1'');
As for your onload question, what''s wrong with just doing <body
onload="javascript stuff">?
Or if you have a layout and view files:
layout.rhtml:
<body <%= yield :body_tag %> >
some_action.rhtml
<% content_for(:body_tag) do %>
onload="javascript stuff"
<% end %>
