You can put a little JavaScript on the page which contains a function that
you can call... for example:
define a JsonHandler:
object PointHandler extends JsonHandler {
def apply(in: Any): JsCmd = in match {
case JsonCmd("setPoint", _, yourData, _) =>
/// do something with yourData
Noop
}
}
Now, build a stable function to send to the browser:
Script(Function("sendPointToServer", "point", PointHandler.call("setPoint",
JsVal("point"))))
You'll have a JavaScript function, sendPointToServer that you cal with the
point and the rest is automatic.
Thanks,
David
