Hi,
I need a prototype/javascript guru to take a peek at this.
There''s been discussions about prototype.js missing full support for
the :on parameter to field_observer
eg this is ignored, and always defaults to on "change", whether you
use "focus", "keyup" , "blur" whatever
<%= observe_field ''foo'', :on => "focus",
:function => ''Element.show
("foobar")'' %>
here''s some background:
http://dev.rubyonrails.org/ticket/9003
http://groups.google.com/group/rubyonrails-talk/browse_thread/thread/
b297e6e10c1989fc?hl=en (discusses "blur")
http://jonathan.tron.name/articles/2006/07/21/working-on-forms-with-
prototype (specific to "focus")
http://joshhuckabee.com/rails-observe-field-function-and (general
solution)
The joshhuckabee article seems the best generalized solution, gives a
patch to prototype.js
but seems out of date w/r/t Rails 2.0 prototype.js When I add the
patch, FireBug goes into an infinite loop adding errors:
Form.Element.getValue is not a function
return Form.Element.getValue(this.element);
It''s probably a simple fix to get it to work again. But I dont know
js that well...
