Calling a v8 javascript function from c++ with an argument

I haven’t tested this, but it’s possible that something like this will work:

// ...define and compile "test_function"

Handle<v8::Object> global = context->Global();
Handle<v8::Value> value = global->Get(String::New("test_function")); 

if (value->IsFunction()) {
    Handle<v8::Function> func = v8::Handle<v8::Function>::Cast(value);
    Handle<Value> args[2];
    args[0] = v8::String::New("value1");
    args[1] = v8::String::New("value2");

    Handle<Value> js_result = func->Call(global, 2, args);

    if (js_result->IsInt32()) {
        int32_t result = js_result->ToInt32().Value();
        // do something with the result
    }
}

Edit:

It looks like your javascript function expects a single argument (consisting of an array of two values), but it kinda looks like we’re calling func by passing in two arguments.

To test this hypothesis, you could change your javascript function to take two arguments and compare them, e.g.:

function test_function(test_arg1, test_arg2) { 
  var match = 0; 
  if (test_arg1 == test_arg2) { 
    match = 1; 
  } else { 
    match = 0; 
  } 
  return match; 
}
