HTMLObjectElement: validity 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 validity read-only property of the HTMLObjectElement interface returns a ValidityState object that represents the validity states this element is in. Although <object> elements are never candidates for constraint validation, the validity state may still be invalid if a custom validity message has been set.
Value
A ValidityState object.
Examples
The following example demonstrates that an <object> is in an invalid state when a customError is set; in this state, checkValidity() returns true while the validityState's validity property is false.
js
const objectElem = document.getElementById("myObjectElm");
objectElem.setCustomValidity("This object element is invalid.");
const validityState = objectElem.validity;
console.log(validityState.valid); // false
console.log(validityState.customError); // true
console.log(objectElem.checkValidity()); // true
