Thanks Anton, that was stupid of me.... :)
...another question related to that. Is there anyway to get v8::Function
from args[0]? to make the same call from c++.
static v8::Handle<v8::Value> func(const v8::Arguments& args) {
if (args.IsConstructCall())
return v8::Undefined();
args[0] to v8::Function function; ???
function.As<v8::Function>()->Call(args.This(), 0, NULL)
...
}
