Hey,

I’m trying to create AJAX website with Rails. I ran into the following  
problem:

I want to add a Song to my database. There is this \_form.rhtml where I  
can edit all Song’s attributes. Then I can click ‘Create’ and I’m  
done. I want to switch this to AJAX. I thought about using  
form\_remote\_tag, but it seems insufficient to me. One of Song’s  
attributes is a list of lyrics authors. I edit this list as follows:  
you can enter new author in a text field and press ‘Add’ or you can  
click ‘Remove’ on any of existing authors. Unfortunately, to implement  
this I’d have to use another remote form and I would land with nested

 tags, which is prohibited. So... I think that maybe I could use link\_to\_remote or remote\_function, but... I would somehow have to pull out text field values and send them as parameters of the link\_to\_remote. Can I do that? And how?

Thanks,

Mike

you can change form action to different by javascript…

with :  
link\_to “button”, “#”, :onclick = “document.forms.myform.action = ‘/  
new/action’;”

OR if i am lost something:  
you have Song.authors model ?  
you can pass:  
hidden\_field “song”, “authors[]”, @song.authors  
in this way ^.

Hmm, maybe my description was too complicated… I need this:

I have an in my page and I want to  
include it’s value in an XML-RPC call performed by link\_to\_remote. How  
can I do that?
