If I write a GET AJAX request using remote function, how can I configure  
it to pass the values of form fields.

Assume that I have a ZIP code field in a form, and I write something  
like this:

remote\_function(:url =\> {:action =\> ‘lookup\_city\_and\_state’,  
:object\_name =\> object\_name,  
:check\_state =\> check\_state ? ‘1’ : ‘0’,  
:mailing =\> mailing ? ‘1’ : ‘0’})

how would I pass the form value from my ZIP code field - or can it be  
done?

I already have the Javascript version of this AJAX request working but  
was wondering if I could use the remote\_function idiom instead.

Thanks,  
Wes

Wes,

Did you try the :with option?

e.g

:onclick =\> remote\_function(  
:url =\> {:action =\> :preview},  
#:with =\> “‘name\_of\_form\_field’=value\_you\_want\_and\_javascript\_is\_legal”  
:with =\>  
“‘patch[editing\_rdoc]=’+$(‘patch\_modified\_rdoc\_source’).value”,  
:before =\> “$(‘preview\_target’).innerHTML=’…loading…’”,  
:failure =\> “$(‘preview\_target’).innerHTML=‘Ajax error!’”,  
:update =\> ‘preview\_target’  
) + ‘;return false;’

Also you can use the submit option

\<%= submit\_tag ‘Save’, :name =\> ‘save’, :id =\> ‘save’ %\>  
\<%= submit\_tag ‘Update Preview’,  
:name =\> ‘preview’,  
:onclick =\> remote\_function(  
:url =\> {:action =\> :preview, :\_method =\> :post},  
:submit =\> “id\_of\_my\_form”,  
:before =\> “$(‘preview\_target’).innerHTML=‘…loading…’”,  
:failure =\> “$(‘preview\_target’).innerHTML=‘Ajax error!’”,  
:update =\> ‘preview\_target’  
) + ‘;return false;’  
%\>

information on various ways of doing this.

Jinal,

Thanks. I thought :with might work but didn’t see it in the API docs.

Generally, I find that finding a true comprehensive list of Prototype  
API function parameters, or finding a comprehensive list of RoR AJAX-y  
function parameters can be somewhat challenging.

I wonder if anyone is working on a _complete_ Prototype/Script.aculo.us  
reference?

Anyhow, thanks again, all works great.

Wes
