HTMLObjectElement: validationMessage property

Baseline Widely available

This feature is well established and works across many devices and browser versions. It’s been available across browsers since December 2018.

The validationMessage read-only property of the HTMLObjectElement interface returns a string representing a localized message that describes the validation constraints that the control does not satisfy (if any). This is the empty string if the control is not a candidate for constraint validation (willValidate is false), or it satisfies its constraints.


A string.
