Definering og brug

formaction egenskab bestemmer, hvor formulardata skal sendes, når formularen sendes. Denne egenskab vil overskrive formularens action egenskab.

formaction egenskab bruges kun til type="submit" knapperne.

Eksempel

En formular med to send-knapper. Den første send-knap sender formulardata til "action_page.php", den anden til "action_page2.php":

<form action="/action_page.php" method="get">
  <label for="fname">Fornavn:</label>
  <input type="text" id="fname" name="fname"><br><br>
  <label for="lname">Efternavn:</label>
  <input type="text" id="lname" name="lname"><br><br>
  <button type="submit">Submit</button>
  <button type="submit" formaction="/action_page2.php">Submit to another page</button>
</form>
