Datetime-local

The datetime-local input uses HTML's native datetime-local picker to allow users to easily select a date and time based on their browser’s locale.

Pro Alternative

Need more flexibility than the native HTML datetime-local input provides? Check out the datepicker input available in FormKit Pro.

Basic example

<FormKit  type="datetime-local"  value="2020-03-13T18:22"  label="End of the world"  help="When will the end of the world take place?"  validation="required|date_after"  validation-visibility="live"/>

End of the world

When will the end of the world take place?

End of the world must be in the future.

Formatting

The internal format of all native datetime-local pickers is YYYY-MM-DDTHH:MM. This is true even though the format of the datetime-local displayed to the user may be different. For example U.S. based browsers display datetime-local format as MM/DD/YYYY, HH:MM AM/PM.

Props & Attributes

The datetime-local input has no unique props but can make use of the following universal FormKit props.

Prop	Type	Default	Description
Commonly used native attributes
`min`	`Number`		View on MDN
`max`	`Number`		View on MDN
`step`	`Number`	`auto`	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..
