$('form').validator();| Option name | Possible values | Description |
|---|---|---|
| data-validation | required / false | Validates the field when set to true. |
| data-validation-type | text / phone / email / checkbox / radio / select | Which method used to validate field. Each type has its own. |
| data-validation-text | any string | Text used as error message. Otherwise validator will use its own messages for every field type. |
| Type | Description | Available input types |
|---|---|---|
| text | Validates text field. Input can have additional attribute data-validation-condition with available length and equal values. If set to length - Validator will look for data-min-length, data-max-length or data-length attributes. If set to equal - Validator will look for data-equal attribute. Then validator will match value with values from attributes. | input / textarea |
