我需要从javascript中删除某个会话变量

Question

I need to erase a certain session variable from a javascript function how can i do this?

Answer 1

I don't think this is possible. Sessions live on the server (not strictly true I know, but for the purposes of this answer, it's true enough).

I would write a script (PHP or somesuch) that unsets the session variable and fire off an ajax call to it.
