Unless your JS potentially conflicts with standard javascripts, I would say
"try to make this JS as less intrusive as possible, avoid dependencies on other
javascripts where possible, expose as less global symbols as possible (hint :
use Firebug to check for available symbols), and leave the TALES expression
empty".
Otherwise, just add a view that does this in your browser/utils.py that makes
the check :
<browser:view
name="plonetheme-xxx-is-js-required"
for="Products.CMFPlone.interfaces.IPloneSiteRoot"
class=".utils.JSCondition"
permission="zope.Public" />
class JSCondition(BrowserView):
def __call__(self):
# Your own cooking
return TrueOrFalse
and use "portal/@@plonetheme-xxx-is-js-required" in the TALES condition field
in the JS registry. Same can apply to other registries.
