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.
