Remove parent element on click with plain javascript

Question

I am trying to learn stuff I was used to do in jQuery do in plain JavaScript.

I have example I found on the internet to solve and it really gave me hard time.

I am trying to remove parent div.single on click on button.remove.

Here is the code;

 var btn = document.getElementsByClassName('remove')
    
 for (var i = 0; i < btn.length; i++) {
    btn[i].addEventListener('click',function (e) {      
      e.parentNode.parentNode.removeChild(e.parentNode);
    } , false);
 }

 <div class="single">
    <img src="http://via.placeholder.com/150x150">
    <button type="button" class="remove">X1</button>
  </div>
  <div class="single">
    <img src="http://via.placeholder.com/150x150">
    <button type="button" class="remove">X2</button>
  </div>
  <div class="single">
    <img src="http://via.placeholder.com/150x150">
    <button type="button" class="remove">X3</button>
  </div>
  <div class="single">
    <img src="http://via.placeholder.com/150x150">
    <button type="button" class="remove">X4</button>
  </div>

I am getting error e.parentNode is undefined.

Here is the jQuery code which does the same I am after.

$(document).ready(function() {  
  $(document).on('click', '.remove', function () {    
    $(this).parent('.single').remove()
  })
})

Thanks for any answers.

Answer 1

To remove parent node as short way:

<div class="single">
   <img src="http://via.placeholder.com/150x150">
   <button type="button" onclick="return this.parentNode.remove();" class="remove">X</button>
</div>

You need to get the element reference from the event object(currentTarget/target)

Note: All the modern browser's have support for Node.remove()

var btn = document.getElementsByClassName('remove')

for (var i = 0; i < btn.length; i++) {
  btn[i].addEventListener('click', function(e) {
    e.currentTarget.parentNode.remove();
    //this.closest('.single').remove() // in modern browsers in complex dom structure
    //this.parentNode.remove(); //this refers to the current target element 
    //e.target.parentNode.parentNode.removeChild(e.target.parentNode);
  }, false);
}

<div class="single">
  <img src="http://via.placeholder.com/150x150">
  <button type="button" class="remove">X1</button>
</div>
<div class="single">
  <img src="http://via.placeholder.com/150x150">
  <button type="button" class="remove">X2</button>
</div>
<div class="single">
  <img src="http://via.placeholder.com/150x150">
  <button type="button" class="remove">X3</button>
</div>
<div class="single">
  <img src="http://via.placeholder.com/150x150">
  <button type="button" class="remove">X4</button>
</div>
