我怎样才能使 HTML/NodeJS 表单根据响应转到另一个表单，有点像 Google 表单的“根据答案转到部分？”

Question

So I have a NodeJS site and on the home page is a form containing some radio buttons. When the user clicks "Submit," I would like for the user to be redirected to another page based on the answer. This I have figured out (The buttons have an onclick attribute that changes the action attribute of the form element). However, I need to keep the data from the original form, so that after the user has "chosen their path," I know what path the took and the answers they made along it. Thank you in advance!

You could persist the client's state in a session. If you're using express, one alternative could be express-session . The way it works is that it assigns a unique identifier to the user in the form of a cookie and saves the data somewhere (memory, database, a file, etc. depending on which you choose). Then when the client makes another request, the server gets that data back with the identifier from the cookie.
