# Subscribing to Events

The following code example shows how to call the `subscribe` method within a Visualforce page to subscribe to specified events published from a canvas app.

```java
// Subscribe to a single event.
Sfdc.canvas.controller.subscribe({name : 'mynamespace.myevent0', 
                                  onData : function (e) {}});

// Subscribe to multiple events in a single call.
Sfdc.canvas.controller.subscribe([
    {name : 'mynamespace.myevent1', onData : function(e) {}},
    {name : 'mynamespace.myevent2', onData : function(e) {}}
]);

```
