如何在v8中创建REAL全局对象？

Question

我用v8引擎创建程序,它可以运行JS代码,如:

警报( '试验'); // alert函数在C++中创建,并设置为v8上下文.所以它可以运行.

window.name ='aa'; // window对象从C++导出到v8环境.

但是,如果我将属性设置为窗口对象,如:

window.name ='aa';

然后,我访问它:

警报(名); // -------->这导致错误,名称未定义...

在Chrome中,我们可以为窗口属性名称设置属性,任何字符串.它运行正常.

那么我该如何实现呢？似乎窗口在JS上下文中是真正的全局.

我的代码:

Isolate* isolate = Isolate::GetCurrent();
Isolate::Scope isolate_scope(isolate);
HandleScope handle_scope(isolate);


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

v8::Handle<v8::FunctionTemplate> log_ft = v8::FunctionTemplate::New(isolate, log_Callback);
log_ft->InstanceTemplate()->SetInternalFieldCount(1);
global->Set(isolate, "alert", log_ft);


Handle<Context> context = Context::New(isolate, NULL, global);
Context::Scope context_scope(context);


// set global objects and functions

Local<Object> obj( Object::New(isolate));
context->Global()->Set( String::NewFromUtf8(isolate, "window"), obj );



runJSCode(context, (char*)"window.name =33; alert(name);");

std::cout << "********* v8 executed finished !! ********** \n";
return 0;

Answer 1

//Local<Object> obj( Object::New(isolate));
//context->Global()->Set( String::NewFromUtf8(isolate, "window"), obj );

runJSCode(context, (char*)"window=this; window.name =33; alert(name);");

==== 就这么简单-_-！
