Formaction

Formaction is an HTML attribute used on form-associated controls such as input and button elements that submit a form. It specifies the URL to which the form's data will be sent for that particular submit action, overriding the form element's action attribute for that submission. The control can be part of the form or associated with it via the form attribute, which allows a single page to submit to different endpoints using different controls.

When a control with a formaction is activated, the browser uses the URL provided by formaction as the submission target. If formaction is not present on the control, the action attribute of the form is used. Formaction works together with related form-level attributes such as formmethod, formtarget, and formnovalidate to customize the submission: formmethod specifies the HTTP method (get or post), formtarget selects the browsing context, and formnovalidate disables form validation for that submission.

Compatibility: formaction is part of HTML5 and is supported by all major browsers, with very old browsers lacking support. It is useful when a form must submit to multiple endpoints without duplicating the form content.

Example: <form id="main" action="/process" method="post"> ... <button type="submit" formaction="/save" formmethod="post" formtarget="_self">Save</button> <button type="submit" formaction="/archive" formmethod="get" formtarget="_blank" formnovalidate>Archive</button> </form>
