The formaction attribute works when let’s say you have two submit buttons in your form and you want both the buttons to work separately. Both the buttons send data to different pages. The formaction attribute overrides the form action attribute.
Note − The formaction attribute is not supported in Internet Explorer 9 and earlier versions.
