Access Javascript variable in Razor code

Question

I want to pass javascript variable in the C# method which is call from the Razor page. May I know how can I do that? (I refer this link but it did not work for me.)

Answer 1

You can't do something like this, because razor works in render time of the page. UserID is not available at render time, thats why you can not pass it as a variable to servercode.

if you need to call SomeMethod on runtime, you can make a ajax request for it.
