AbsolutePosition- und CursorLocation-Eigenschaft (Beispiel) (JScript)

In diesem Beispiel wird veranschaulicht, wie die AbsolutePosition-Eigenschaft den Fortschritt einer Schleife nachverfolgen kann, die alle Datensätze eines Recordset-aufzählt. Sie verwendet die CursorLocation-eigenschaft, um die AbsolutePosition-Eigenschaft zu aktivieren, indem der Cursor auf einen Clientcursor festgelegt wird. Schneiden Sie den folgenden Code aus, fügen Sie ihn in Editor oder einem anderen Text-Editor ein, und speichern Sie ihn als AbsolutePositionJS.asp.
