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 July 2015.
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.
Value
A string.
