推荐答案

您必须手动添加此功能，这是我的操作方式:

You have to add this functionality manually, here is how I did it:

Handle<Value> Include(const Arguments& args) {
    for (int i = 0; i < args.Length(); i++) {
        String::Utf8Value str(args[i]);

        // load_file loads the file with this name into a string,
        // I imagine you can write a function to do this :)
        std::string js_file = load_file(*str);

        if(js_file.length() > 0) {
            Handle<String> source = String::New(js_file.c_str());
            Handle<Script> script = Script::Compile(source);
            return script->Run();
        }
    }
    return Undefined();
}

Handle<ObjectTemplate> global = ObjectTemplate::New();

global->Set(String::New("include"), FunctionTemplate::New(Include));

它基本上增加了一个可全局访问的功能，该功能可以在当前上下文中加载和运行javascript文件.我在项目中使用它，就像梦一样.

It basically adds a globally accessible function that can load and run a javascript file within the current context. I use it with my project, works like a dream.

// beginning of main javascript file
include("otherlib.js");
