Überprüfen ob ein Popupfenster schon existiert

[Markus]

hey,

müßte Dir helfen... ich habs in PHP verwendet, daher die "echos" !

echo "<script>";
echo "function openWindow(url)";
echo "{";
echo "if(typeof(popFenster) != "object"){";
echo "popFenster = window.open (url, 'ChangeView', 'height=450,width=200,left=0');";
echo "}";
echo "else {";
echo "if (!popFenster.closed){";
echo "popFenster.location.href = url;";
echo "} else {";
echo "popFenster = window.open (url, 'ChangeView', 'height=450,width=200,left=0');";
echo "}";
echo "}";
echo "popFenster.focus();";
echo "}";
echo "</script>";
