Hi,

I read the following in the API-docs

JS_ExecuteScript executes a previously compiled script, script. On
successful completion, rval is a
pointer to a variable that holds the value from the last executed expression
statement processed in
the script.

What happens when the script only contains a function? I returns undefined.
Wouldn't it be nice when the function object is returned?

I want to use this to implement a better way for event handling in wxJS. eg.

frame.onClose = wxScript("close.js");

close.js looks like this

function onCloseHandler()
{
  ....
}

I've found a workaround for this in JavaScript :

function onCloseHandler()
{
  ....
}

function doit()
{
  return onCloseHandler;
}

doit();

This works because JS_ExecuteScript puts the return value of doit into rval.
Is there a way to avoid this workaround?

Franky.
