Variables

read only badInput:Bool

Is a Boolean indicating the user has provided input that the browser is unable to convert.

read only customError:Bool

read only patternMismatch:Bool

Is a Boolean indicating the value does not match the specified pattern.

read only rangeOverflow:Bool

read only rangeUnderflow:Bool

Is a Boolean indicating the value is less than the minimum specified by the min attribute.

read only stepMismatch:Bool

read only tooLong:Bool

Is a Boolean indicating the value exceeds the specified maxlength for HTMLInputElement or HTMLTextAreaElement objects. Note: This will never be true in Gecko, because elements' values are prevented from being longer than maxlength.

read only typeMismatch:Bool

read only valid:Bool

Is a Boolean indicating the element meets all constraint validations, and is therefore considered to be valid.

read only valueMissing:Bool
