javascript - How to pass a variable to a listener/handler function -


I am using projekktor for streaming my video on the browser. I have an event attached to many listeners on state . 

  video.addListener ('state', listener1); Video.addListener ('state', listener 2); Video.addListener ('state', listener3);

The function inside listener3 and when state === 'COMPLETED' I need to remove the listener listener3 The thing is that the listener You need a variable video to delete. Given that the listener3 is a callback, how can I pass variable video in function listener3?

To remove an event listener in javascript use:

Modern Browser: 

  Video .removeEventListener ('name', fnName);

Older means: 

  video.detachEvent ('name', fnName);

DOM Level 0: 

  Video '[name' = name] = 'null;

jQuery: 

  video.off ('name');
