mouseover fromelement Exception

[plan_B]

Hallo,

var fromElement = event.relatedTarget || event.fromElement || false;
document.getElementById('debug').innerHTML += "<br>";
document.getElementById('debug').innerHTML += fromElement.id;

  
 if (fromElement)  
    document.getElementById('debug').innerHTML += fromElement.id;  

macht's sicherer ...

Gruß plan_B
