The formEnctype property of the HTMLInputElement interface is the MIME type of the content sent to the server when the <input> with the formEnctype is the method of form submission. It reflects the value of the <input>'s formenctype attribute.
This property is valid only for submit and image <input> elements.
Its value overrides the enctype property of the HTMLFormElement interface if the form is submitted via the input. This property can be retrieved or set. If not set, the value is the empty string ("").
