Question

Please check the below code:

var clickfn = function(){
 alert("clicked");                    
}
document.getElementById("div1").addEventListener("click",clickfn,true);
clickfn = function(){  };
document.getElementById("div1").removeEventListener("click");

Why does the removeEventListener does not work?

Answer 1

removeEventListener takes 2 parameters, the event, and the function to remove.
This should work:

document.getElementById("div1").removeEventListener("click", clickfn);

Also, the function you’re executing is empty.

var clickfn = function(){  };
