I need to add an event handler to the window object to remove all the event listeners you created. The event to use is beforeunload. Remember to remove the event listener on the window object as well. How do I do this?
In my code, I have 3 event listeners.
Do I add the remove event listener for each event I have?
Hi @jlusty, yes and you also need to pass the used callback function (and options if originally provided):
How do I specify that it removes the event listener on beforeunload?
Doesn’t the event listener get automatically removed anyway when the page is unloaded?
By adding an
beforeunload event listener, which will again remove previously added event listeners… but I don’t think that’s necessary either, you shouldn’t have to worry about this.
