stepMismatch
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
step
属性。
If the field is numeric in nature, including the
date
,
month
,
week
,
time
,
datetime-local
,
number
and
range
types and the step value is not
any
, if the value don't doesn't conform to the constraints set by the
step
and
min
values, then
stepMismatch
will be true. If the remainder of the form control's value less the
min
value, divided by the
step
value (which defaults to 1 if ommitted) is not zero, there is a mismatch.
Given the following:
<input type="number" min="20" max="40" step="2"/>
if
(value - min) % 2 != 0
,
stepMismatch
will be true.
If true, the element matches the
:invalid
and
:out-of-range
CSS pseudo-classes.
