RJS collection proxy

I would like to update the class of all <a> tags found in a div of my page.. I can get it all (seeing the index and value) using :

page.select("#header_domain_map a").each do |value, index|   page << 'alert(value);' end

but how can I set the classof all these elements to class="active"

Just because RJS can be used to generate JavaScript doesn't mean it's the easiest way to accomplish things in JavaScript. I assume that you are using Prototype since you are using RJS at all, so:

page << '$$("#header_domain_map a").each(function(a) { a.className = "active"; });'
