Ratchet / When.js：“未捕获的ReferenceError：模块未定义”

Question

I'm trying to use ratchet for reflecting the changes made to my database realtime. I used the code of the pusher app (http://socketo.me/docs/push). But i am getting error in that.

The moment I open the client side page :

Uncaught ReferenceError: module is not defined                    when.js:900
(anonymous function)                                              when.js:900
(anonymous function)                                              when.js:15
(anonymous function)                                              when.js:900

After this I typed: conn.subscribe('topic'); //This subscribes the topic.

Now the moment I make changes to this topic, an error pops up where the changes are to be displayed.

Error 2 :

Uncaught TypeError: undefined is not a function         [VM] autobahn.min.js (124):66
(anonymous function)                                    [VM] autobahn.min.js (124):66
c._websocket.onmessage                                  [VM] autobahn.min.js (124):66

Any help ?

Answer 1

This may be solvable by using the following JavaScript before including the when.js file:

window.define = function(factory) {
    try{ delete window.define; } catch(e){ window.define = void 0; } // IE
    window.when = factory();
};
window.define.amd = {};

Then, include your when.js file.
