Get variables on the fly (windows) without send them ?

[davnis]

Dear Firend, Im apologise becuase I make a mistake and I was understand wrong. Sorry for that ! And thanks for the reply !
Realy friends are here ...

My problems is :
I open from a php ( browser window ) a new window using
JavaScript. In the second window (that is open on the fly) I whant to have the vars from the first window without send them with "?vars=1&vars2=2" etc
Is that posible ? I any way that I make the variables to be readen from any window that is open on the fly ?
I have to declare this variable somehow in the first window ?

Thank you a lot.

e.g. on the main window put it in a hidden field and read it out in the popup with window.opener.document. (bla bla you know how to in JS I hope)
