This feature is well established and works across many devices and browser versions. It’s been available across browsers since July 2015.
The formNoValidate property of the HTMLInputElement interface is a boolean value indicating if the <form> will bypass constraint validation when submitted via the <input>. It reflects the <input> element's formnovalidate attribute.
This property is valid only for submit and image <input> elements.
Its value overrides the noValidate property of the HTMLFormElement interface if the form is submitted via the input. This property can be retrieved or set.
A boolean.
const inputElement = document.getElementById("myInput");
console.log(inputElement.formNoValidate);
