// this C++ function is callable from JS
Handle<Value>myFunction(Argments& args) {
v8::Local<v8::Value> func = args[x];
v8::Persistent<v8::Function> func =
v8::Persistent<v8::Function>::Cast(obj);
v8::Handle<v8::Value> returnObj =
func->Call(v8::Context::GetCurrent()->Global(),
<argcount>, <args>);
return Undefined();
}
In your main code, you make it accessible to JavaScript:
globalObject->Set("myFunction", FunctionTemplate::New(myFunction));
You set the globalObject when you create your context.
The JavaScript code can do:
myFunc(JS_fun);
If you'd like to see a straightforward use of v8, you might look at my
project:
