This is my source code, i set env2 global to evn1 global, but result is "v
= undefined".
#include <v8.h>
using namespace v8;
static inline v8::Local<v8::String> v8_str(const char* x)
{
return v8::String::NewFromUtf8(v8::Isolate::GetCurrent(), x);
}
static inline v8::Local<v8::Value> CompileRun(const char* source)
{
return v8::Script::Compile(v8_str(source))->Run();
}
int main(int argc, char* argv[])
{
v8::V8::Initialize();
Isolate* isolate = Isolate::New();
{
Isolate::Scope isolate_scope(isolate);
v8::HandleScope scope(isolate);
v8::Handle<Context> env1 = Context::New(isolate);
{
Context::Scope scope(env1);
env1->Global()->Set(v8_str("v"), v8_num(1));
}
Local<Object> global = env1->Global();
v8::Handle<Context> env2 = Context::New(isolate, NULL,
Handle<ObjectTemplate>(), global);
env2->SetSecurityToken(env1->GetSecurityToken());
{
Context::Scope scope(env2);
Local<Value> value =
env2->Global()->Get(v8_str("v"));
printf("v = %s\n", *String::Utf8Value(value));
}
}
isolate->Dispose();
v8::V8::Dispose();
return 0;
}
