Rails - Mar 2010 - Form Question

I have a custom form builder that output form elements as <li> tags.

So

<%= form.input :first_name%>
<%= form.input :last_name%>

generates like..

<ol>
<li>
first_name_label - first_name_text
</li>
<li>
last_name_label - last_name_text
</li>
</ol>

I want to provide a link next to the text fields and I do that like..


<%= form.input :first_name%>
<%= form.input :last_name%>

<%= link_to_function "clear", :id => ,
"this.up(''li'').remove()" %>

This works fine but the link is located outside of the <li> tag which
causes the formatting to be weired. How can I generate this link and
position it within the <li> tag it is supposed to remove? I think the
answer might be very simple, i am just not clear about how to move an
elements while creating it.

I would recommend you do it either as:

 <%= form.input :last_name, :links => [{:name => "clear",
:function =>
"this.up(''li'').remove()"}] %>

or:

<% form.input :last_name do %>
    <%= link_to_function "clear", :id => ,
"this.up(''li'').remove()" %>
<% end %>

Either way you''re going to have to amend your custom form builder. 
Your
form builder is already outputting the <li>.  If you''re doing it
the second
way (which I''d recommend as it''s more flexible) remember you
can''t have <%with do/end so you have to use concat to output the
content if block_given?
(within your input method).

Alternatively, you could do it with jQuery or something similar - give the
link a class and then have a DOM ready event move any items with that class
within the previous sibling.

Cheers,


Andy
