There's not a great, general way to do this in Haml 1.8. For the first
example, you could do
- content_for :onload_scripts do
== $(#{highlighted_item.to_json}).effect('highlight');
Calling out to ERB is probably the best option for the second script.
However, in the master branch you can use filters with variable
interpolation, like so:
- content_for :onload_scripts do
:plain
$('#search_items').autocomplete(
#{url_for(:controller => '/items', :action => 'search').to_json},
{ selectFirst: false, minChars: 2 });
Note that I'm calling to_json on the strings before putting them into
the document; that guarantees that they'll result in valid Javascript.
