Well, It seems like you could use broadcastChannel [1] to send message (not callback) among pages. If this is not enough, you have to use low level C++ api to implement it by yourself, which is hard to write and not encouraged.
A message among pages is not enough in your case? I'd like to here the detail. FYI: Apache Weex excludes global JS object for security reasons. A malicious hacker could inject a JS snippet containing dangerous function just by loading his URL in Weex. If global JS object is supported, it's very easy for you to excute the JS function provided by malicious hacker in your page. That's reason we design Sandbox. And I'd encourage every developer keeping if for security reason.
