AddNew-Methode – Beispiel (VBScript)

  • Artikel

In diesem Beispiel wird die AddNew-Methode verwendet, um einen neuen Datensatz mit dem angegebenen Namen zu erstellen.

Verwenden Sie das folgende Beispiel in einer Active Server Page (ASP). Verwenden Sie Find (Suchen), um die Datei „Adovbs.inc“ zu suchen und in dem Verzeichnis zu platzieren, das Sie verwenden möchten. Schneiden Sie den folgenden Code aus, fügen Sie ihn in Editor oder einen anderen Text-Editor ein, und speichern Sie ihn als AddNewVBS.asp. Sie können das Ergebnis in jedem beliebigen Clientbrowser anzeigen.

Fügen Sie zum Üben des Beispiels einen neuen Datensatz in dem HTML-Formular hinzu. Klicken Sie auf Add New (Neue hinzufügen). Weitere Informationen zum Entfernen unerwünschter Datensätze finden Sie im Beispiel für die Delete-Methode.
