The url input uses HTML's native url input. It allows a user to enter a single URL.
Although FormKit supports the url input type, the primary reason this input is provided in the HTML spec is validation. Since FormKit has its own validation system the utility provided by this input is not significant and can complicate your form submissions. In most cases you are better off using a text input with the url validation rule.
The url input has no unique props but can make use of the following universal
FormKit props.
| Prop | Type | Default | Description | ||
|---|---|---|---|---|---|
| Commonly used native attributes | |||||
| minlength | Number | none | View on MDN | ||
| maxlength | Number | none | View on MDN | ||
| placeholder | String | none | View on MDN | ||
| Show Universal props | |||||
| config | Object | {} | Configuration options to provide to the input’s node and any descendent node of this input. | ||
| delay | Number | 20 | Number of milliseconds to debounce an input’s value before the commit hook is dispatched. | ||
| dirtyBehavior | string | touched | Determines how the "dirty" flag of this input is set. Can be set to touched or compare — touched (the default) is more performant, but will not detect when the form is once again matching its initial state. | ||
| errors | Array | [] | Array of strings to show as error messages on this field. | ||
| help | String | '' | Text for help text associated with the input. | ||
| id | String | input_{n} | The unique id of the input. Providing an id also allows the input’s node to be globally accessed. | ||
| ignore | Boolean | false | Prevents an input from being included in any parent (group, list, form etc). Useful when using inputs for UI instead of actual values. | ||
| index | Number | undefined | Allows an input to be inserted at the given index if the parent is a list. If the input’s value is undefined, it inherits the value from that index position. If it has a value it inserts it into the lists’s values at the given index. | ||
| label | String | '' | Text for the label element associated with the input. | ||
| name | String | input_{n} | The name of the input as identified in the data object. This should be unique within a group of fields. | ||
| parent | FormKitNode | contextual | By default the parent is a wrapping group, list or form — but this props allows explicit assignment of the parent node. | ||
| prefix-icon | String | '' | Specifies an icon to put in the prefixIcon section. | ||
| preserve | boolean | false | Preserves the value of the input on a parent group, list, or form when the input unmounts. | ||
| preserve-errors | boolean | false | By default errors set on inputs using setErrors are automatically cleared on input, setting this prop to true maintains the error until it is explicitly cleared. | ||
| sections-schema | Object | {} | An object of section keys and schema partial values, where each schema partial is applied to the respective section. | ||
| suffix-icon | String | '' | Specifies an icon to put in the suffixIcon section. | ||
| type | String | text | The type of input to render from the library. | ||
| validation | String, Array | [] | The validation rules to be applied to the input. | ||
| validation-visibility | String | blur | Determines when to show an input's failing validation rules. Valid values are blur, dirty, and live. | ||
| validation-label | String | {label prop} | Determines what label to use in validation error messages, by default it uses the label prop if available, otherwise it uses the name prop. | ||
| validation-rules | Object | {} | Additional custom validation rules to make available to the validation prop. | ||
| value | Any | undefined | Seeds the initial value of an input and/or its children. Not reactive. Can seed entire groups (forms) and lists.. | ||
You can target a specific section of an input using that section's "key", allowing you to modify that section's classes, HTML (via :sections-schema, or content (via slots)). Read more about sections here.
| Section-key | Description |
|---|---|
| outer | The outermost wrapping element. |
| wrapper | A wrapper around the label and input. |
| label | The label of the input. |
| prefix | Has no output by default, but allows content directly before an input element. |
| prefixIcon | An element for outputting an icon before the prefix section. |
| inner | A wrapper around the actual input element. |
| suffix | Has no output by default, but allows content directly after an input element. |
| suffixIcon | An element for outputting an icon after the suffix section. |
| input | The input element itself. |
| help | The element containing help text. |
| messages | A wrapper around all the messages. |
| message | The element (or many elements) containing a message — most often validation and error messages. |
