Some of the third party plugin will attach the
eventListener into the site. How to I remove the eventListener without knowing the function that attached.
I refer this removeEventListener but I can't get any clue to remove this.
getEventListeners(window) shows the events attached. But, when I try to remove the event using
window.removeEventListener("eventname") is not working without knowing that function.
Please help, Thanks in advance.
getEventListeners(window) will return a map of events and their registered event listeners.
DOMContentLoaded event for example you can have many event listeners. If you know the index of the listener you want to remove (or if there exists only one), you can do:
var eventlistener = getEventListeners(window)["DOMContentLoaded"][index]; window.removeEventListener("DOMContentLoaded", eventlistener.listener, eventlistener.useCapture);
Unfortunately, you cannot do that. You need to have a reference to the event handler function in order to remove it by
Your only option if you cannot get that reference would be by entirely replacing that
