Trying to use onfocus , onfocusout, or finding which element has focus has lead to a problem. In the program I give at the end, if you click out of a input element I can not find where the focus goes. FF does not do both things - focus out and focus on at the same time. I have tried multitude ways of trying to find where focus goes when leaving this element. Have not tried oither elements.

My code:

<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1">
</head>

<body style="padding-left: 20px">
<input onfocusout="myFunction(0);" ><br><br>
<input onfocusout="myFunction(1);" ><br><br>
<input onfocusout="myFunction(2);" ><br><br>
<input onfocusout="myFunction(3);" >

<script>
function myFunction(top){
    alert(top);
    var bottom = document.activeElement.id;
    alert(bottom);    
}
</script>
</body>
</html>

Try to ask advice on a web development oriented forum.

This might be easier to see what is happening.
