HTMLButtonElement: formEnctype 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 formEnctype property of the HTMLButtonElement interface is the MIME type of the content sent to the server when the form is submitted. It reflects the value of the <button>'s formenctype attribute.

The value overrides the enctype property of the HTMLFormElement interface if the form is submitted via the submit button. This property can be retrieved or set. If not set, the value is the empty string ("").

Value

A string.

Examples

js
btnEl.formEnctype = "application/x-www-form-urlencoded";
