Grails - set variable from javascript function

Question

When I tried to set a variable from javascript function in GSP view I had error: "Cannot invoke method func() on null object"

GSP:

<g:set var="variable" value="${tr.func.name()}" />

I also tried to the get around the problem without success: variable is undifined

<g:javascript>var test = tr.func.name();</g:javascript>
<g:set var="variable" value="${test}" />
<g:javascript>alert(${variable});</g:javascript>

Thanks

Answer 1

You should use Javascript in browser. GSP works on server side.

Just pass date in GMT to browser, and apply formatting there. There is a good js library for Date formatting: moment.js

Answer 2

You can't do that. <g:set> is used to set server-side variables within the GSP. Javascript is client-side.
