我正在尝试将函数硬编码为字符串,将其转换为函数并运行它。

Local<Function> cb = "function(){ console.log('HELLO BOSS'); }";
int argc=0;
v8::Handle<v8::Value> * argv;
cb->Call(Context::GetCurrent()->Global(),argc,argv);

编译器说我不能直接这样做:

      error C2664: 'v8::Handle<T>::Handle(T *)' : cannot convert parameter 1 from 'const char *' to 'v8::Function *'
      with
      [
         T=v8::Function
      ]
      Types pointed to are unrelated; conversion requires reinterpret_cast, C-style cast or function-style cast 
      x.cpp(15) : see reference to function template instantiation 'v8::Local<T>::Local<const char>(S *)' being compiled
      with
      [
         T=v8::Function,
         S=const char
      ]

那我该怎么办?此外,所有好东西(eval、new Function 等)都在哪里?

我做到了。男孩,我喜欢这个东西。

v8::Script::Compile(v8::String::New(
    " console.log('WORKS BOSS'); "
    " console.log('Happy?'); "
    " console.log('2+2=' + (2+2)); "
))->Run();

我不知道它是否正确(就像“任何相关风险”一样),但它似乎有效。
