{{item}} displays data in the browser. but i want to transfer this item data to the scala side. the one with the @, because i need the item in:

 @form(routes.Application.newItem({{item}})){....}

whenever i run this. it displays.

You can't do that directly, keep in mind that JavaScript is client-side technology and Scala template is backend one. That means that Play compiles the view long, long before the client (and its JS) will see it.

You have 2 solutions:

1. Replace action attribute of form tag using JavaScript
2. You can also use Play's JavaScript routes to create url (also using javascript after page rendering)
