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": $value})
and then in the jsx extension...
var PARAMETER_ONE =
"$escapetool.javascript($request.getParameter('param'))";
Thanks,
Caleb

Did you also check that this $param is correctly set a value in your
velocity code ?
The fact that "param" is undefined on javascript side is strange, if it
didn't find anything in the velocity context, it should contain exactly the
string '$xcontext.macro.params.parameter', not undefined.
So it seems to me it was found in the context, but it has null value.
Exactly. I'm needing initialize a value in
the velocity environment and
use it on the javascript code. it not needs to be
dinamic.
I am trying to use the following code but the JS
variable is returning
"undefined"
Java Script Code
var param;
this.param="$xcontext.macro.params.parameter";
console.log(param);
Velocity (Macro)
$xcontext.put("param", $xcontext.macro.params.parameter)
Some light?
