hi

I have a few questions about JS_CompileFunction. I did browse
http://lxr.mozilla.org/mozilla/ident?i=JS_CompileFunction but didnt found
any sample use.

I don't understand what the obj parameter is for. The Apidoc says it's the
"object with wich the function is associated", but why would I want to do
that, since I have to pass an object when i call JS_CallFunction.
The second one is this, but what's the first one?
It the first one associating a function to an object the same way as
JS_DefineFunction does? If so, does it mean my newly compiled function will
be callable from javascript by my user, provided the object is in his scope.
How should i hide it from him (since it's an event handler, not supposed to
be fired by an user)

Maybe I'm totally misunderstanding something : here is what I want to do :
I have a class jsmethod with 2 functions : init and do.
init take a string containing a script (and a description of the arguments)
and compile it to a JSFunction *
do takes an JSObject * (and an argument list) and calls the function
I call Init once to compile the javascript script, and after that each time
the event occurs, i call do to actually execute the javascript

Is this a correct approach?

thx for helping
