Why it's not possible to just do this...

Hi, I can't understand this binding events function. Why can't we just instead ( ie. for fixing delete button ) do something simple like this:

// Select all buttons with delete class
var delbuttons = document.getElementsByClassName("delete");
// Function to delete "li" element
var deleteTask = function() {
  var listItem = this.parentNode;
  var ul = listItem.parentNode;
  ul.removeChild(listItem);
}
delbutton.addEventListener("click", deleteTask );

Shouldn't this now be ready on all delete buttons so once you click them you call deleteTask function ?

Hi Denis

I think the problem is that var delbuttons = document.getElementsByClassName("delete"); returns an array and it binds only the array and not the particular button to the click event.

Maybe you can try this and see if it works: for(var i = 0; i < delbutton.length; i++) { delbutton[i].addEventListener("click", deleteTask ); }

Good luck!
