v8學習---添加有返回值的js全局函數

#include <v8.h>
using namespace v8; 
void get_name(const v8::FunctionCallbackInfo<Value>& args)
{
    args.GetReturnValue().Set(String::New("Headool"));
}
int main()
{
    Isolate* isolate = Isolate::GetCurrent();
    HandleScope handleScope(isolate);

    Handle<ObjectTemplate> global = ObjectTemplate::New();
    global->Set(String::New("get_name"), FunctionTemplate::New(get_name));

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

    Handle<Script> script = Script::Compile(String::New("get_name()"));
    Handle<Value> value = script->Run();
    String::AsciiValue ascii(value);
    printf("%s\n", *ascii);
    return 0;
}

留意其中的：

    args.GetReturnValue().Set(String::New("Headool"));
