Generic page element display initializer in a layout?

Rails
1

All,

I’ve run into a snag. I need to handle the display of elements on my
page and I want to use my Javascript event handlers on page load.

However, my BODY tag is trapped in my generic layout.

I’m thinking that I can put an onLoad on the BODY tag that will just
call a Javascript method called initializePage() and then provide this
initializePage() call in my specific page to call whatever handlers I
need to in order to display things correctly.

Something in the back of my head is screaming AJAX but not sure how I
would get that in.

Any thoughts?

FYI, this kind of Javascript scheme will work, but I think I just need
to make my template smarter, so I will do that instead.

Wes-

You can also use the content_for  method to push dynamic content

from your view up to the master layout.

So in your normal view:

<% content_for :javascript do %>

# blah blah more javascript <% end %> So in your layout: <%= yield :javascript %> -Ezra

Whoa - so content_for generates a block that can then be yielded to in
any of the enclosing templates?

Yeah, pretty sweet way to push dynamic content up from the partials

or templates into the layout. This is a very powerfull feature once
you start playing with it. Makes your layouts much more flexible and
reuseable because your normal views can specialize the layout.

As I sometimes say when I get excited - that is f-in ballz!
