HTMLFieldSetElement: 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 HTMLFieldSetElement interface returns a string representing a localized message that describes the validation constraints that the <fieldset> control does not satisfy (if any). This is the empty string as <fieldset> elements are not candidates for constraint validation (HTMLFieldSetElement.willValidate is false).
Value
The empty string, "";
