I would like to write a link\_to\_function that is dynamic in the sense  
that it inserts something into a div based on the value of a hidden  
field.

So at the moment I have

page.insert\_html :bottom, :div\_name, :partial =\>  
‘partial\_name’, :object =\> 5

I would like to do

page.insert\_html :bottom, :div\_name, :partial =\>  
‘partial\_name’, :object =\> value of a hidden form field

If it is not possible by the partial method, is it possible to have

page.insert\_html :bottom, :div\_name, html string

Where the html string contains some javascript that picks up  
the hidden field value.

I know how to do this with raw javascript but would love to do it in a  
cleaner rails/RJS fashion.

Thanks for any tips

Anthony
