rangeOverflow
property of a
ValidityState
object indicates if the value of an
<input>
, after having been edited by the user, does not conform to the constraints set by the element's
max
属性。
If the field is numeric in nature, including the
date
,
month
,
week
,
time
,
datetime-local
,
number
and
range
types and a max value is set, if the value don't doesn't conform to the constraints set by the
max
value, the
rangeOverflow
property will be true.
Given the following:
<input type="number" min="20" max="40" step="2"/>
if
value > 40
,
rangeOverflow
will be true. When
true
, the element matches the
:invalid
and
:out-of-range
CSS pseudo-classes.
