I am trying to find an event listener I have attached to the document, but when I console.log it i get an error. I have tried to get do getElementById and getElementsByClassName, but i couldn't see the Event listener I attached to it. Here is a test code 

document.addEventListener('keydown', test,false);

function test(e) {
     console.log(document);
}

What i want to do is grab the event listener save it and re-added later on in another class. Something 

var savedListener = document._listener; 
document.removeAllEventListener();

and maybe in another class for example

document._listener = savedListener ;

You can store the different parameters of your event in a variable and use it later:

var evtToSave = {
  "event": 'keydown',
  "function": test,
  "useCapture": false
};

document.addEventListener(evtToSave.event, evtToSave.function, evtToSave.useCapture);

function test(e) {
  console.log(document);
}

//document.removeAllEventListener();
document.removeEventListener(evtToSave.event, evtToSave.function);


document.addEventListener(evtToSave.event, evtToSave.function, evtToSave.useCapture);

  • That way is fine but if i have something 2 classes. I don't want the other class to know what event function it has. just needs to know save that event and add it later after executing your stuff. so if both class has the keypress event handler it doesnt need to know what it is. just need to know it has a listener save it and apply later. do you get what i mean? – user629283 Jan 20 '16 at 12:13
