Recent Script.aculo.us tutorial

Rails
1

I would like to add a visual effect to one of my web pages and in the
stage
where I don’t know what I don’t know. I’ve talked to my buddy Google
about
this and (s)he has pointed me at a number of different web pages that
all
seem to have 2006 dates on them. I can try looking at them more
carefully
(and will keep looking), but I thought I would toss my question out to
you
folks in the mean time.

I would like to display (in my #index view) a table of some data. Most
(if
not all) of the rows have other data associated with them. I would like
to
display a plus sign next to each row which, when clicked by the user,
would
expand the view to include the associated data – sort of like the way
Gmail
can expand and collapse “conversations”.

Can anybody point me at a recent tutorial that might get me started down
this path?

Thanks…

Sounds like you just need to learn Javascript. Doesn’t seem like a
Rails problem/question at all.

That’s a fair reply. I have read (without understanding) a number of
different posts about how great “RJS” is because it hides all of that
messy
Javascript from the Rails developer. I imagine one can only appreciate
how
great RJS is once one has a certain amount of Javascript experience and
has
learned how messy it can be.

I’ll head down that path. Thanks.

There are different paths you can take. Prototype/Scriptaculous is
(currently) incorporated into the framework, so that can be an easy
place to start (particularly when using rjs to deal with controller-
type actions in your controllers).

Another route is to learn and use jQuery or another javascript
frameworks). These may behave differently, and have benefits or
weaknesses when compared with Prototype.

The API documentation for the frameworks themselves are really helpful
places to start. For using them with Rails, railscasts.com is a
fantastic place to get pointers (search for ‘rjs’, ‘prototype’ or
‘jQuery’).

Hi,

you will simply need to create a div with the data in a hidden row
below and add the javascript to the onclick option.
This is actually so simple that it not worth encapsulating this in
rails, imho.

Check this link:

If you have the time get a copy of the book Ajax on Rails (O’Reilly).
It’s excellent.
