class Formtastic::Actions::LinkAction

Outputs a link wrapped in the standard `<li>` wrapper. This the default for `:cancel` actions. The link's URL defaults to Rails' built-in `:back` macro (the HTTP referrer, or Javascript for the browser's history), but can be altered with the `:url` option.

@example The `:as` can be ommitted, these are functionally equivalent

<%= f.action :cancel, :as => :link %>
<%= f.action :cancel %>

@example Full form context and output

<%= semantic_form_for(@post) do |f| %>
  <%= f.actions do %>
    <%= f.action :submit, :as => :input %>
    <%= f.action :cancel, :as => :link %>
  <% end %>
<% end %>

<form...>
  <fieldset class="actions">
    <ol>
      <li class="action input_action" id="post_submit_action">
        <input type="submit" value="Create Post">
      </li>
      <li class="action link_action" id="post_cancel_action">
        <a href="javascript:history.back()">Cancel</a>
      </li>
    </ol>
  </fieldset>
</form>

@example Modifying the URL for the link

<%= f.action :cancel, :as => :link, :url => "http://example.com/path" %>
<%= f.action :cancel, :as => :link, :url => "/path" %>
<%= f.action :cancel, :as => :link, :url => posts_path %>
<%= f.action :cancel, :as => :link, :url => url_for(...) %>
<%= f.action :cancel, :as => :link, :url => { :controller => "posts", :action => "index" } %>

@example Specifying a label with a String

<%= f.action :cancel, :as => :link, :label => "Stop" %>

@example Pass HTML attributes down to the `<a>`

<%= f.action :cancel, :as => :link, :button_html => { :class => 'pretty', :accesskey => 'x' } %>

@example Access key can also be set as a top-level option

<%= f.action :cancel, :as => :link, :accesskey => 'x' %>

@example Pass HTML attributes down to the `<li>` wrapper (classes are appended to the existing classes)

<%= f.action :cancel, :as => :link, :wrapper_html => { :class => 'special', :id => 'whatever' } %>
<%= f.action :cancel, :as => :link, :wrapper_html => { :class => ['extra', 'special'], :id => 'whatever' } %>

@todo document i18n keys @todo document i18n translation with :label (?) @todo :prefix and :suffix options? (can also be done with CSS or subclassing for custom Actions)
