Question

This line works fine

        <%=link_to_function "name", "$('#thing_name').html('<p>name<p>')" %>

This line doesn’t

        <%=link_to_function "name", "$('#thing_name').html('<%= escape_javascript(thing.name) %>')" %>

Then I get rid of all the content within <%= %>

       <%=link_to_function "name", "$('#thing_name').html('<%= %>')" %>

It still keeps complaining about some weird compile errors.

Thanks in advance.

You are already inside an ERB block due to the opening <%= at the very beginning, and you cannot use another one. Use string interpolation to evaluate Ruby code inside the string:

<%= link_to_function "name", "$('#thing_name').html('#{escape_javascript(thing.name)}')" %>

Alternatively, if for some reason you don’t want to use interpolation:

<%= link_to_function "name", "$('#thing_name').html('" + escape_javascript(thing.name) + "')" %>
