Create Custom Data

Select Button-> Properties -> Advanced -> User Data. For example, type 123, as the following picture shows.

C++

The previous version cocos2d-x 3.8:

#include "cocostudio/CCObjectExtensionData.h"
.....
auto button = _rootNode->getChildByTag("XXX");

auto userdata = ((cocostudio::ObjectExtensionData*)(rootNode->getUserObject()))->getCustomProperty();
CCLOG("%s", userdata.c_str());    

cocos2d-x 3.8 and later version:

#include "cocostudio/CCComExtensionData.h"
.....
auto button = _rootNode->getChildByTag("XXX");

ComExtensionData* data = dynamic_cast<ComExtensionData*>(child->getComponent("ComExtensionData"));
auto userdata = data->getCustomProperty();
CCLOG("%s", userdata.c_str());

JS

var button = mainscene.node.getChildByTag(XXXXX);
var userdata = button.getUserData();
cc.log(userdata);    

Lua
