#ifndef

[learner]

Hi,

Is there anyth like #ifndef variable in javascript?

I want to declare a varibale in a global file.

This file is included in all links.

I want to keep the variable value visible across links by using
#ifndef
then define variable
#endif in other links.

Is it possible?

[#If we are talking about javascript in hhtml-files]

Including a javascript file in many pages does not make it a "global file".

Variables can be kept:
- serverside [ASP session variables or database with login]
- by posting them to the next page with serverside detection
- Clientside in cookies
- Clientside by sending them to the next link by querystring
[- Any guru knows more ways?]
