How do I pass variables into an rjs?

I’d like to do:

page.replace\_html “frame\_set\_\<%=job.id%\>”, :partial =\> ‘list\_frame\_set’

where

\<%= link\_to\_remote “Display Frame Sets”, :url =\> {:action =\>  
:toggle\_frame\_set, :id =\> job} %\>

is in the view and

def toggle\_frame\_set  
@job = Job.find\_by\_id params[:id]  
end

is in the controller.

@job is passed to the partial, and it works fine if I hard code in an id  
in the rjs, I just need some way to pass the id to the javascript.

</div>

page.replace\_html :dom\_id, :partial =\> ‘list\_frame\_set’, :locals =\> {  
:dom\_id =\> “frame\_set\_#{@job.id}” }

Doesn’t work either.

Hmm… I figured out something that worked, but I still think that some  
other way should work.

I added:  
@dom\_id = “frame\_set\_#{@job.id}”  
to the controller. Then I changed the rjs to:  
page.replace\_html @dom\_id, :partial =\> ‘list\_frame\_set’

have you tried that? or #{@job} make sure it’s in double quotation marks

Hi Jonathan,

use the below options

\<%= link\_to\_remote “Display Frame Sets”, :url =\> {:action =\>  
:toggle\_frame\_set, :locals=\>{:job =\> @job}} %\>

insted of

> \<%= link\_to\_remote “Display Frame Sets”, :url =\> {:action =\>  
> :toggle\_frame\_set, :id =\> job} %\>

hope this works
