Below is the HTML code snippet where I am trying to display an alert during unload event. But I am not able to see the alert.
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8" />
<meta name="viewport" content="width=device-width, initial-scale=1" />
<meta name="theme-color" content="#000000" />
<title>IE App</title>
</head>
<body>
<h3>I am IE Compatible app.</h3>
<div id="demo"></div>
<script>
document.getElementById("demo").innerHTML = "Javascript is enabled";
window.addEventListener('unload', function(event) {
alert('Unload event from IE Modal');
});
</script>
</body>
</html>
I can see from browser settings JavaScript pop ups are enabled. In IE browser console, I checked if alert works, it is working. I tried adding alert outside the unload event listener. I can see the alert pop up. I tried adding console.log() instead of alert, I can see the console logs. But the problem is only with alert inside unload event which is not displaying.
Can you please help me to know where I am going wrong and why alert inside unload event is not displaying?
