Is there anyway to remove an event listener added like this:
element.addEventListener(event, function(){/* do work here */}, false);
Without replacing the element?
To call removeEventListener with an anonymous function with JavaScript, we assign the anonymous event listener function to a variable and call addEventListener and removeEventListener with the variable.
Event listeners can also be removed by passing an AbortSignal to an addEventListener() and then later calling abort() on the controller owning the signal.
TLDR; Always remove event listeners when you don't plan on using them any longer.
There is no way to cleanly remove an event handler unless you stored a reference to the event handler at creation.
I will generally add these to the main object on that page, then you can iterate and cleanly dispose of them when done with that object.
You could remove the event listener like this:
element.addEventListener("click", function clicked() { element.removeEventListener("click", clicked, false); }, false);
