HTMLButtonElement: formAction property

Baseline Widely available

This feature is well established and works across many devices and browser versions. It’s been available across browsers since July 2015.

The formAction property of the HTMLButtonElement interface is the URL of the program that is executed on the server when the form that owns this control is submitted. It reflects the value of the <button>'s formaction attribute.

The value overrides the action property of the HTMLFormElement interface if the form is submitted via the button. This property can be retrieved or set.

Value

A string. The URL for form submission.

Examples

js
btnEl.formAction = "/cgi-bin/publish";
