Last week I released a new minor version of the Helperful GEM. This is essentially a bugfix release, although it comes with one minor new feature: the javascript_content_for tag. The following overview is taken directly from the documentation.
The javascript_content_for helper combines the features of content_for and javascript_tag into a single helper.
1 2 3 | <% javascript_content_for :head do %> $("#id").hide(); <% end %> |
The block is passed as it is to javascript_tag, then the result is stored as content_for :head.
Now you can call yield and output your javascript content.
1 2 | <%= yield :head %> <script>$("#id").hide();</script> |
This example is equal to the following statements.
1 2 3 4 | <% javascript_content_for :head do; javascript_tag do %> $("#id").hide(); <% end; end %> <% javascript_content_for :head do %> <script>$("#id").hide();</script> <% end %> |
This feature also addresses an annoying bug in the has_content helper method caused by an undefined variable.
To install or upgrade:
1 | gem install weppos-helperful --source http://gems.github.com |
More features still to come. Visit the project page for further details.
