Hi all,
I want to create charts in my website. I want to fill them with
variables. So in my controller, I put the variables I want to use :
class ChartsController < ApplicationController
def show_one_publisher_seven_days
@title = ''foo''
end
end
And in my view (show_one_publisher_seven_days.haml), I want to assign
my javascript variable with the variable I created in my controller.
%script{:type => "text/javascript"}
var title_text = <% @title %> <<<==============
%p This is the chart for one publisher for the last seven days
%div{:id => "7days_one_publisher", :style => "width: 800px;
height:
400px; margin: 0 auto"}
but it doesn''t work... Do you know how to do that ?
Thanks

Try = "var title_text = #{@title}" Check the html generated in the browser to check it is what you expect. By the way, it is generally considered bad form to put javascript like this in the view.

Are you getting some kind of Javascript error? I don''t know haml yet, but it looks to me like that would probably result in saying: var title_text = foo whereas you want:: var title_text = ''foo''; Try adding the quotes and semicolon and see what happens. If that doesn''t fix it, see if you''re getting a JS error, and if so, tell us what it is. -Dave -- Specialization is for insects. | Professional: http://davearonson.com -Robert Anson Heinlein | Programming: http://codosaur.us -------------------------------+ Leadership: http://dare2xl.com Have Pun, Will Babble! -me | Et Cetera: http://davearonson.net -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

What you want to do instead is put the value in a hidden div, then have your JS look at that div. You should never have to generate JS dynamically from Ruby.> > ColinBest, -- Marnen Laibow-Koser http://www.marnen.org marnen-sbuyVjPbboAdnm+yROfE0A@public.gmane.org -- Posted via http://www.ruby-forum.com/. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

I have not seen the == syntax previously, it does work, but I cannot see it documented at http://haml-lang.com/docs/yardoc/file.HAML_REFERENCE.html Am I just missing it there?
