Short answer is You can't

You wont be able to pass/convert JavaScript variable to a Razor variable. Razor variable is handled by Razor engine where as JavaScript on the other hand is a client side language running on the client.

Razor is a view engine used by the ASP.NET MVC framework running on the server to produce some HTML template.
