You have not provided any code, so it is difficult to give you specific help, but in this way Should give something in some direction:

Poo.h 

  class JSObject; Square poo: cocos2d :: CCNode {public: static zero hello (JSObject * target, std :: string selector); }   
 Poo.cpp  
  Poo :: hello (JSObject * target, std :: string selector) {if (target) {js_proxy_t * p; JS_GET_PROXY (P, Target); If (! P) {return; } Jaswal Ratwal; JSL Data Val = Std_String_to_Jeswal (Scriptingcore :: getInstance () - & gt; getGlobalContext (), "Hello World"); Scriptingcore: Receive () - & gt; With performance work (OBJECT_TO_JSVAL (P-> OBJ), selector cistrated (), 1, and datawal, and retal); }}   
 Then, in your JS file:  
  var demo = cc.Node.extend ({ctor: function () {this._super ( ); // Normal Init stuff Poo.hello (this, "myCallback");}, myCallback: function (msg) {cc.log ("I received the message from C ++:" + msg);}} );
