Options

message

type: String default: This value is not a valid ISSN.

The message shown if the given value is not a valid ISSN.

caseSensitive

type: boolean default: false

The validator will allow ISSN values to end with a lower case 'x' by default. When switching this to true, the validator requires an upper case 'X'.

requireHyphen

type: boolean default: false

The validator will allow non hyphenated ISSN values by default. When switching this to true, the validator requires a hyphenated ISSN value.

payload

type: mixed default: null

This option can be used to attach arbitrary domain-specific data to a constraint. The configured payload is not used by the Validator component, but its processing is completely up to you.

For example, you may want to use several error levels to present failed constraints differently in the front-end depending on the severity of the error.
