Form Question

#1

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.

<%= 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

  • tag which

    causes the formatting to be weired. How can I generate this link and

    position it within the

  • 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

  • . 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,
