removeEventListener timeline

[Romanus 4 Likes (Newbie)]

Hello! I have a timeline. I want tl.play() to work on a computer and not work on a phone.

 

 

The click listener is added like this:

element.addEventListener("click", handler)

 

The click listener is removed like this:

element.removeEventListener("click", handler)

 

 

if you add a listener like this:

element.addEventListener("click", ()=>handler())

then this listener can't be removed (I couldn't)

 

My problem is that tl.play is only added like this:

element.addEventListener("click", ()=>tl.play())

This means I can't remove it. Help me please.

I think that will only work if you assign the arrow function to a variable as removeEventListener requires a reference to the function.

@PointC Indeed.

 

@Romanus You have to first define the handle function and then use that handler function inside the event listener. Later, you will be able to easily remove that event listener when needed. Check the example. There you can see that for first 2 second you are able to click the square (still have the event listener). But, after 2 seconds event listener is removed.
