Greetings! What is up with the syntax of this thing? I mean, if the only thing I can send back using :with is the field being observed, then why in the world is the syntax so convoluted? For example, what I''ve been able to get working is: <%= text_field_tag(''date'', illness_date, :size => 30) %></p> <%= observe_field(''date'', :url => {:action => ''update_date'', :id => illness_id}, :with => "''idate=''+$(''date'').value" ) %> Of course, maybe I''m just doing it wrong. I suppose it might make some sense if it''s possible to send more than one params value back with the :with option. Does anybody know anything about how that might be possible? I''ve spent a day and a half trying to figure it out and haven''t been able to get anything but the above to work. TIA, Bill -------------- next part -------------- An HTML attachment was scrubbed...

Hi Bill, You can send anything back to your script. The syntax is pure javascript that is eval''d. You can use it to build a custom parameter string. I''m not sure if it needs to be escaped to be url encoded or not. :with => %q{"idate=" + $(''date'').value + "&some_other_value=" + $(''some_other_field'').value} Hope this is strictly correct. I''m sure someone will correct me otherwise :) at least I hope so. On 6/26/06, Bill Walton <bill.walton@charter.net> wrote:> > Greetings! > > What is up with the syntax of this thing?

Hi Daniel, Thanks. I haven''t tried the %q syntax (although that''s about the _only_ thing I haven''t tried!). I''ll give it a shot. I did find something on the wiki just after I sent my original post that implies you can only send back one params value _but_ you can put a bunch of stuff into the one string you''ll get back and then parse out the pieces. I definitely hope your approach works, but at least it looks like there''s a way to do what I need, even if it''s coyote-ugly ;-) Thanks again, Bill ----- Original Message ----- From: Daniel N To: rails@lists.rubyonrails.org Sent: Monday, June 26, 2006 8:57 AM Subject: [Norton AntiSpam] Re: [Rails] syntax for observe_field( :with => Hi Bill, You can send anything back to your script.

I guess you could wrap it up into a helper. There''s no doubt a much better way to do this. def with_fields_for_observe( *fields ) fields.flatten! out = "" join = "" fields.each do |field| out << join << "''#{field.to_s}='' + $(''#{field.to_s}'').value" join = " + ''&'' + " end out end Then you could call the with parameter with :with => with_fields_for_observe( :a_field_id, ''some_other_id'', [:yet_another_id, :last_one] ) The access in your controller should be similar to a normal parameter string. Best to check the output tho. Hope this minimises the ugly to a reasonable level. ;) Thanks again,> Bill > > ----- Original Message ----- > *From:* Daniel N <has.sox@gmail.com> > *To:* rails@lists.rubyonrails.org > *Sent:* Monday, June 26, 2006 8:57 AM > *Subject:* [Norton AntiSpam] Re: [Rails] syntax for observe_field( :with > => > > Hi Bill, > > You can send anything back to your script.
