Ich habe eine sellhouse.jsp, wo ich versuche, die Werte, z. B. Name und Adresse vom Benutzer zu bekommen und diese in die Datenbank einzufügen. Bevor die Werte in die Datenbank eingefügt werden, versuche ich das JavaScript aufzurufen, um den Geocode der vom Benutzer eingegebenen Adresse zu erhalten. Aber bevor ich das Formular abschicke, wird das Skript ausgeführt. Aber ich möchte, dass das Skript ausgeführt wird, sobald ich auf "Senden" klicke. Außerdem möchte ich, dass der Geocode an das Element jsp übergeben wird.JavaScript von JSP aufrufen
Hier ist die sellhouse.jsp
