<h2>The oncontextmenu Event</h2>
<p>This example uses the addEventListener() method to attach a "contextmenu" event to a div element.</p>

<div id="div01" style="border:1px solid black; padding:10px">
<p>Right-click in this box to see the hidden content!</p>
</div>

<div id="myDiv" style="visibility:hidden">
<p>This info is hidden</p>
<p>This info is hidden</p>
<p>This info is hidden</p>
</div>

// Prevent default context menu:
const div = document.getElementById("div01");
div.addEventListener("contextmenu", (e) => {e.preventDefault()});

// Show hidden content:
function myFunction() {
  const div = document.getElementById("myDiv");
  div.style.visibility = "visible";
