I run the following JS code in the Chrome console: // Version 67.0.3396.87 (Official Build) (64-bit)
function Car(make) { this.make = make } var car = new Car('Ferrari') car instanceof Car // returns true Now, on my C++ code I get ahold of car (by looking "car" up in the global context), and want to run the equivalent instanceof code, given only the class name "Car" as a string. Notice that I do not have a C++ class / function backing up Car. Just to make it clear, compiling and running "car instanceof Car" as JS code in my C++ code, works totally fine. I naively tried to do something like this, which didn't work: Local<Object> object = FindObject("car"); // this works Local<FunctionTemplate> ft = FunctionTemplate::New(isolate); Local<String> name = String::NewFromUtf8( isolate, "Car", NewStringType::kNormal).ToLocalChecked(); ft->SetClassName(name); if (ft->HasInstance(object)) { // this never happens } How can I do this, without manually compiling / running JS code?
