This feature is well established and works across many devices and browser versions. It’s been available across browsers since July 2015.
The autocomplete property of the HTMLFormElement interface indicates whether the value of the form's controls can be automatically completed by the browser. It reflects the <form> element's autocomplete attribute.
A string; the value "off" if explicitly set to "off", and otherwise always "on".
const formElement = document.getElementById("name");
console.log(formElement.autocomplete);
