Right click menu not displaying in correct position

Question

I am trying to create a edit and delete option for a list of items for which i have made it display when user right click on that list item.

document.addEventListener('contextmenu', function(e) {
  e.preventDefault();
  var x = e.offsetX;
  var y = e.offsetY;
  var d = document.getElementById("context-menu");
  d.style.display = "block";
  d.style.left = x + 'px';
  d.style.top = y + 'px';
  console.log(x, y);
}, false);

#context-menu {
  display: none;
  position: absolute;
  color: blue;
}

.listItems li {
  padding-bottom: 25px;
}

<ul class="listItems">
  <li>I am list one</li>
  <li>I am list two</li>
  <li>I am list three</li>
  <li>I am list four</li>
</ul>

<ul id="context-menu">
  <li> Edit </li>
  <li> Delete </li>
</ul>

And the jsfiddle link was, https://jsfiddle.net/dmfvz5qw/1/

Here when i make a right click, the id named context-menu is not displaying nearby the mouse arrow and it is showing at more top of the clicked list.

I am in the need to display the context-menu nearby right clicked position rather than any other position.

Kindly help me to fix the issue and also i am in the need of result in Pure Javascript.

Answer 1

Please use clientX and clientY instead:

var x = e.clientX;
var y = e.clientY;

Answer 2

You need to use clientX and clientY here,

If you want to learn more about the positioning using body scroll position too, then refer this link https://stackoverflow.com/a/7790764/2630817

 document.addEventListener('contextmenu', function(e) {
 e.preventDefault();
 document.getElementById("context-menu").display = 'none';     
 var x = e.clientX ;
 var y = e.clientY;
 var d = document.getElementById("context-menu");
 d.style.display = "block";
 d.style.left = x+'px';
 d.style.top = y+'px';
 console.log(x,y);
}, false);

#context-menu {
  display: none;
  position: absolute;
  color: blue;
  padding: 0;
  width:50px;
}

<ul class="listItems">
  <li>I am list one</li>
  <li>I am list two</li>
  <li>I am list three</li>
  <li>I am list four</li>
</ul>
<ul id="context-menu">
  <li> Edit </li>
  <li> Delete </li>
</ul>
