How do I use instanceOf operator in native?

[mpgopala]

How do I use a feature similar to instanceOf operator in JS in native CEF? Here is what I am trying to achieve.

JS

Code: Select all

var A = function() {}
var a = new A();
isIntanceOf(a, A);


C++

Code: Select all

//Only the relevant parts of code is shown here...
bool MyHandler::Execute(...)
{
    if(name.compare("isInstanceOf") == 0)
    {
        CefRefPtr<CefV8Value> obj = arguments[0];
        CefRefPtr<CefV8Value> fn = arguments[1];
        bool instance = isInstanceOf(obj, fn); // How do I implement this?
        retval = CefV8Value::CreateBool(instance);
        return true;
    }
}


Thanks in advance for your help.

instanceof is a JavaScript operator so you would need to execute it in JavaScript using CefV8Context::Eval(). The operands would need to be stored as variables in the context. For example, the following untested pseudocode:

Code: Select all

CefRefPtr<CefV8Context> context = CefV8Context::GetCurrentContext();
context->SetValue("_arg0", arguments[0], ...);
context->SetValue("_arg1", arguments[1], ...);

CefRefPtr<CefV8Value> result;
context->Eval("_arg0 instanceof _arg1", result, ...);
