Greetings to you, I''m trying to write a "preview" link, and need to pass along the current value of a text_field to this link. I figure there is some simple Javascript way to do this, but so far haven''t figured it out. Does anyone know how to get and pass the current value of a text_field to link_to? -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

FWIW, I''m opening "preview" in another window. For right now, I plan on passing the current value of the text_field by setting params[:body] equal to it, but that doesn''t seem to be the best idea. Is there a better way to pass the current value to the "preview" action? -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Where is the value in the text field coming from? If it''s coming from
your app (e.g. from the database or from a user passing parameters),
then you can do this on the Rails side of things, and it seems most
likely that you want to set an instance variable in the controller
(e.g. @text_field_value = [value]), which you can then use in both
your link_to and text_field. If you want the text field to
dynamically update as the value of the text field is changed, then you
should use Javascript, such as something along these lines:
<input type="text"
onkeyup="$(''link'').innerHTML = this.value" />
<a href="preview..." id="link"> Default text
</a>
Best of luck,
Greg

I''m having trouble passing the value of link to the "preview" action... instead, when I hit "preview" now, it shows value of the text field below the text field. I guess I just need to set the value of a ruby variable equal to link.innerHTML somehow... -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Man, maybe I am making this more complicated than it should be.
I just need to pass whatever is in the text_field to a "preview"
action
when I click a "preview" link. So I don''t really need to
dynamically
update anything, but when "preview" is clicked, I want to get what is
in
the text_field and pass it to my "preview" action.
To make it clearer, when someone clicks "Preview Post", I want @body
to
be set to whatever is in the text_field.
<%= link_to "Preview Post", {:action => :preview, :id =>
@topic.id,
:body => @body}, {:id => ''link'', :target =>
"_blank"} %>
Any ideas?

The only problem is if I hit "Preview Post" multiple times, it keeps adding onto body, but I can fix that problem. It''s times like these that I realize I need to learn more javascript. -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
