Is anyone else finding it frustrating to do in Ruby client-side things
that would be simple in Javascript?
It seems like all of the "helpers" involve server (controller)
communication.
For example, having a text field that just echos below what the user
types.
Is this the only way to do it?
<div id=''word_panel''>
<%= text_field_tag ''user_text''%>
<%= javascript_tag("Event.observe(''user_text'',
''keypress'',
function(event) { Element.update(''stylized_word'',
$F(Event.element(event)));})")%>
<div id=''show_word''></div>
Thank you!
Chris

Chris, this is just the example. You might want to use that for chat for example, where text that user types appears not only on his computer, but for others. Clearly, if you are doing it for one user there is no point in using server-side, but again this is just the example Chris Hackel wrote:> Is anyone else finding it frustrating to do in Ruby client-side things > that would be simple in Javascript? > It seems like all of the "helpers" involve server (controller) > communication. > > For example, having a text field that just echos below what the user > types. > Is this the only way to do it? > > <div id=''word_panel''> > <%= text_field_tag ''user_text''%> > <%= javascript_tag("Event.observe(''user_text'', ''keypress'', > function(event) { Element.update(''stylized_word'', > $F(Event.element(event)));})")%> > > <div id=''show_word''></div> > > > Thank you! > Chris-- Posted via http://www.ruby-forum.com/.

Where there''s server communication, you need a convenient way of keeping the client-side and server-side code in sync. That''s what the helpers help with. If all you''re doing is client-side manipulation, you almost certainly don''t need the helpers. Just use Javascript.> > For example, having a text field that just echos below what the user > types. > Is this the only way to do it?Personally, I wouldn''t bother with the <%= javascript_tag %> call at all... -- Alex
