Answer 1

You can't take a javascript object "foo" as the second parameter. As it is defined in SocketIO.h:

void emit(std::string eventname, std::string args);

The second parameter is a string. Cocos2d-js can't convert a javascript object "foo" to std::string automatically. However, cocos2d-js can convert a javascript string to std::string by jsval_to_std_string().

If you want to send object, you can send object as a string and do decoding on receiving it.
