Ruby on Rails - Send JavaScript to view
- by Eef
Hey,
I am creating a website in Ruby on Rails. I have a controller action that renders a view like so:
def show
time_left = Time.now.to_i - 3.hours.to_i
@character = current_user.characters.find(params[:id])
respond_to do |format|
format.html # show.html.erb
format.xml { render :xml => @character }
end
end
This is fine as it renders the show.html.erb as I like. I would like however to somehow pass time_left to the view as a Javascript variable as this value is use by a countdown JQuery plugin.
I could put a javascript block on the page in the HTML and print a instance variable out like so:
<script type="javascript"> $('#countdown').countdown('<%= @time_left =>')</script>
But I would like to keep all my JS in a external file and off the page could anyone give some advice on how to implement this?
Cheers
Eef
