I am not sure I understand your query, a good way to define velocity variable is to read request parameters #set($myVar = $request.myVar) (will set myVar to blip if the request had a parameter http://xxxx?myVar=blip) In order for a javascript variable to be transmitted to the server, you need to post such a request (e.g. with XHR, or by formulating the appropriate link). Defining a javascript variable from a velocity variable is as simple generating the javascript code: var myVar = "$escaetool.javascript($veloVar)" hope it helps. paul Le 11 nov. 2012 à 18:37, firmusoft.xwiki a écrit :
