typeMismatch property
The read-only typeMismatch 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
type
attribute.
If the type attribute expects specific strings, such as the email and
url types and the value doesn't conform to the constraints set by the
type, the typeMismatch property will be true.
The email input type expects one or more valid email addresses,
depending on whether the
multiple
attribute is present. A valid email address includes an email prefix and a
domain, with or without a top level domain. If the value of the email
input is not an empty string, a single valid email address, or one or more
comma separated email address if the
multiple
attribute is present, there is a typeMismatch.
The url input type expects one or more valid URLs, depending on whether
the
multiple
attribute is present. A valid URL includes a protocol, optionally with an
IP address, or an optional subdomain, domain, and top level domain
combination. If the value of the URL input is not an empty string, a
single valid URL, or one or more comma separated URLS if the
multiple
attribute is present, there is a typeMismatch.
| Input type | Value | Expected value |
|---|---|---|

x@y or x@y.z |
email address, with or without TLD |
url |
x: or x://y.z |
protocol or full URL with protocol |
