focus in javascript
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.
