v8學習---獲取js變量的值

#include <v8.h>
using namespace v8; 
int main()
{
    Isolate* isolate = Isolate::GetCurrent();
    HandleScope handleScope(isolate);
    Handle<Context> context = Context::New(isolate);
    Context::Scope context_scope(context);
    Handle<String> source = String::New("var str = 1 + 2");
    Handle<Script> script = Script::Compile(source);
    script->Run();
    Handle<String> data = String::New("str");
    Handle<Value> str = context->Global()->Get(data); 
    String::AsciiValue ascii(str);
    printf("%s\n", *ascii);
    return 0;
}

留意context->Global()->Get(data);的用法，和data參數的類型是Handle<String>
