how to access the javascript variable in jsp [duplicate]

Answer 1

You can't. The javascript values aren't available on the server, in the servlet the jsp is translated to. You could make an AJAX call at runtime on the client. Also, please don't use scriptlets.

Answer 2

You can't but for alternate solutions you can look at this
