Ross,
This is good code, but introduces a potential security vulnerability. ;-)
fixHtml runs the NodeSeq through Lift's snippet handler. If you have
web-user input, a user could type in <lift:xxxx/> and cause server-side code
to be executed.
import net.liftweb.util._
import Helpers._
Personally, I'd suggest "jQuery(" + AltXML.toXML(nodeSeq, false, true).encJs
+ ")"
Thanks,
David
