Hi, To access to velocity variables from your javascript extension, you need to enable "Parse content" option of the JavaScriptExtension object. That means that your javascript code will be processed by velocity when page is rendered. Then to share a variable between your page and the javascript extension, you can use: ## in macro $xcontext.put("param", "$xcontext.macro.parameter.foo") // in javascript extension def param = "$xcontext.get("param")"; Note: I didn't test that, so I don't know if it works - maybe there's a different way to do.

Hi Sirs,

I am developing a macro in velocity (wiki macro) and need to use a parameter (wiki macro parameter) defined by the user in my java script code (java script extension). I tried can several methods but it is not working.

How can I do this?

Hi, 2014-05-13 8:40 GMT+02:00 Michael Bußler <[email protected]>:

Hi, the velocity-code is executed on the server, while js-code runs on the client side, AFTER the macro-code was executed . You could try need to pass parameters to your macro via an URL parameter or http POST.

Only if value needs to be refreshed without a page refresh. If value comes from a velocity macro, it's in the context of a page, so it's enough to initialize the javascript var from velocity (which is ok as velocity is executed before) - it's not supposed to be updated server-side after the page is rendered. Of course if it needs to be dynamic you could go ajax. Well my understanding of Eduardo is that he needs to initialize a value in javascript, based on a macro parameter passed to a velocity macro.

Hope this helps!

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 On 05/13/2014 03:28 PM, Eduardo Abritta wrote:

Some light?

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.
