What "doesn't work"? Describe your problem more precisely please — Pete, Oct 11 '17 at 08:49
ERB tags (`<%= link_to .. %>`) don't exist in jquery land. So no, it's impossible to "add javascript variable to link_to". But it seems that you just want an `` tag. That you _can_ do. (ProTip: realizing the difference between client-side and server-side and the wall between them is crucial if you want to have anything even remotely complex done). — Sergio Tulentsev, Oct 11 '17 at 08:52

You're mixing server side with client side code. Keeping in mind that the link_to helper is rendered as a "normal" anchor tag, and that you can't mix the ERB code passing JS values, then you can use that anchor, and concatenate the JS values.

Try with:

$('#item').append('<a href="item/' + item_id + '">' + item_id + '</a>')

Being item/ the URI of prd_item_path.

You can't create ERB elements at the client side. ERB is rendered at the server side.

Create the link at the client using JS, as suggested here
