Field observer parameters

Rails
1

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!
