Show and hide from list with toggle

Rails
1

I have a list in my page and I want to show there additional information
like:

my link

  • show me more
    my 2 link
  • show me more
    etc…

I have a element for hidden info:

<%= link.long %>

How can I pass a link id with something like this:

  <%= link_to_function "+", "link_long_id".toggle(), :style =>

‘text-decoration:none’ %>
This does not work.

Thank you!

well assuming the link had id 23, the javascript you’d want to
generate would be $(‘link_long_23’).toggle() - just build up that
string, using the usual string interpolation stuff for example

Yes, but how can I pass link_long_id instead of giving the link_long_23?
I can’t get that working :frowning:

Like I said, string interpolation:

greeting = “world”
puts “hello #{greeting}”

Thank you Fred for your answer, but unfortunately that doesn’t work. I
get an error:
‘undefined method `toggle’ for “link_long_23”:String’
So it gets the id correctly, problem is the toggle? I’m quite new with
all this, so I’m sorry if I ask stupid questions :wink:

If you do that you’re trying to call a ruby function called toggle.
What you want to do is generate a javascript fragment that calls a
toggle function, so .toggle() needs to be inside the string that you
generate, not outside as it is here.

that sounds like you’re still doing something like

link_to_function ,‘blah’, “$(‘something’)”.toggle

That’s not what you want to do. you want to create the string “$
(‘something’).toggle” and pass that as the second argument to
link_to_function (that second argument should be a fragment of
javascript).

Thanks again :slight_smile: I don’t really know how I am supposed to do that :frowning: I’m

<% linkki = (‘link_long_’+link.id.to_s).toggle %>
<%= link_to_function “+”, linkki, :style => ‘text-decoration:none’ %>

<%= link_to_function “+”, “$(‘link_long_id’).toggle()”, :style
=> ‘text-decoration:none’ %>

try

link_to_function “+”, “Effect.toggle (‘$(‘something’)’, ‘slide’);”

this should, if it works, throw in a nice sliding effect for u too…
