This depends a lot on how the javascript is loaded...

If you're including it using $xwiki.jsx.use() then it won't have the same
context because it's a different HTTP request. If you use the macro and then
do a {{velocity}} macro with an {{html}} macro and a <script> inside of that,
the content will (should) be there.

Another solution is to pass the info in a parameter, eg:
$xwiki.jsx.use('My.Document', {"param": $value})
and then in the jsx extension...

var PARAMETER_ONE =3D "$escapetool.javascript($request.getParameter('param'))=
";

Thanks,
Caleb
