proxy is undefined error backboneJS

Question

 var my_variables = {};

_.extend(my_variables,Backbone.Events);

my_variables.on("event_name",function(msg)
{
   alert("easy street"+msg);
});

proxy.on("all", function(eventName) 
{
  my_variables.trigger(eventName);
});

my_variables.trigger("event_name");

Im trying to follow the code by reading the documentation, as far as I understood the proxy.on event is supposed to be called every time any event gets triggered. On this code, I get the error message

"proxy is not defined"

how to fix this here is the spot on the documentation documentation on events!

Answer 1

The example code uses an example object (proxy) to do the call on..

For you to make it work you need to replace proxy with the name of your object.
