TextValidationRule

Defined in: parser/types.ts:591

A validation rule applied to a short or long text response. Rules are evaluated in array order, and the first failing rule is displayed to the participant.

For example, the following rules accept only ReVISit is great: it must start with ReVISit, contain great, not contain invalid, equal ReVISit is great, and not equal TEST. See the MDN regular expression syntax cheat sheet for help writing regular expression patterns.

"textValidation": [
  {
    "type": "matchesRegex",
    "value": "^ReVISit"
  },
  {
    "type": "contains",
    "value": "great"
  },
  {
    "type": "doesNotContain",
    "value": "invalid"
  },
  {
    "type": "equals",
    "value": "ReVISit is great"
  },
  {
    "type": "doesNotEqual",
    "value": "TEST"
  }
]

Property	Type	Description	Defined in
`type`	`TextValidationType`	The operation used to validate the response value.	parser/types.ts:593
`value`	`string`	The regular expression pattern or text value used by the validation operation. Must be non-empty for `equals`, `contains`, and `doesNotContain`. Empty `matchesRegex` and `doesNotEqual` values produce a parser warning because they do not restrict responses.	parser/types.ts:599
