Re: get XEL variable from javascript

Global variables declared in XEL are available in JavaScript as global variables with corresponding names used in the @name attribute of the XEL variable declaration.

So you can basically do:

<e:script type="application/javascript">

  alert(varGroups);

</e:script>

Note that variable will contain not a string but a XMLDocument object, that you might need to serialize (you asked: "how to get String of my variable") with:

<e:script type="application/javascript">

alert(new XMLSerializer().serializeToString(varGroups));

</e:script>

thanks for your help its
