Rails array to jQuery selector

Question

I'm trying to add AJAX for delete action of my controller following railscast 136 - jQuery AJAX revised

It deletes element I choose but it doesn't disappear from the page. The problem is that I can't figure out how to create propper jQuery selector.

I would be ok to use $('#slide_<%= @destroyed_slide_id %>').remove(); for just one slide (no array) but my controller provides @destroyed_slides_ids array. How to create selector from it ?

Just loop over each id in the @destroyed_slides_ids array

<% @destroyed_slides_ids.each do |id| %>
    $('#slide_<%= id %>').remove();
<% end %>

I found a better way. jQuery selector can be used to select multiple elements at once:

$('<%= @destroyed_slides_ids.map { |slide| "#slide_" + slide.to_s }.join(', ') %>').remove();
