field observer parameters

How do I pass more than one parameter through :with in a field observer?

Here is my code:

< %= observe_field(’article_image_id’,    :frequency => 0.25,    :update => ‘image_preview’,    :url => { :action => :image_preview },    :with => “‘id=’+value”) %>

I need to pass also another value. How should I modify the code?

Thanks

You're just building up a string that represents the query string for the http request using javascript,so add '&my_new_param='+my_param_value

I'd like to add that you may need to encode the parameter

:with => "'myparam='+encodeURIComponent($F('form_field_id')) +'&param2='+encodeURIComponent($F('form_field_id'))"

You should indeed be doing that. There's some other ways of doing this, I wrote about it over at

That's the best treatment of the subject I've ever seen!

Thanks, Sheldon.
