Maybe write javascript code that gets all its variables by calling functions.
Then supply those functions as Lift JsXX. This way you can supply values from
Lift but the javascript "program" is written in javascript.

Ross,
I think you and I came to same conclusion. Writing it as raw
JavaScript, as I
did initially, seems the only way I could find to do this. FYI, where
I was using this
was with the TreeView widget. There, "toggle" takes an anonymous
function, and
"this" is an implicit parameter, denoting the Tree selected.
val func = JsRaw("""function() $('#item-save').html(this.id + ' was
toggled')""")
TreeView("tree", JsObj(("persist", "location"),("toggle", func)),
loadTree, loadNode)
I was hoping for a more functional way to write func, in order to do
more complex processing on the client.
