How to safely embed JSON with [removed] in HTML document?

Question

In a Rails 3.1 app, how can I safely embed some JSON data into an HTML document?

Suppose I have this in a controller action:

@tags = [
    {name:\"ta         


        

Answer 1

Your code using just @tags.to_json works in rails3, if you enable it with:

   ActiveSupport.escape_html_entities_in_json = true

Otherwise, your other option is this:

   var tags_list = <%= raw @tags.to_json.gsub(";

This saves the client having to parse the whole thing through $
