[jQuery] $.getScript and variables

[Equand]

Hi everybody... i have a question...
i want to virtualise my admin section... by getting the script from a
php file on post. is this real? and
i want it to use current documents vars... i just copied part of the
script and tried to load it using getScript... but this part doesn't
work, when I put some global variables in it.... is there a way to
make global vars work in included file?
like global $var; in php...
