Instance Method Details

#javascript_content_for(name, content_or_options_with_block = nil, html_options = {}, &block) ⇒ Object

Mixes the features of content_for and javascript_tag into a single helper.

Supports all original method options and features, including the ability to use write the content in a block and javascript tag options.

Examples

<% javascript_content_for :head do %>
  $("#id").hide();
<% end %>

The block is passed as it is to javascript_tag, then the result is stored as content_for :head. Now you can call yield and output your javascript content.

<%= yield :head %>

<script>$("#id").hide();</script>

This example is equal to the following statements.

<% javascript_content_for :head do; javascript_tag do %>
  $("#id").hide();
<% end; end %>

<% javascript_content_for :head do %>
  <script>$("#id").hide();</script>
<% end %>

You can make subsequent calls to javascript_content_for and content_for, the result for each call will be appended to the value currently stored for name.
