Time Input

Type a time one part at a time, on the clock your user's language uses.

Use a Time Input for a time of day, like a meeting or an opening hour. It works like Date Input, with segments for the hour, the minute and, on a 12-hour clock, AM or PM.

<script setup lang="ts">
import { Field, FieldLabel } from "@ui-sdk/vue/field"
import { TimeInput } from "@ui-sdk/vue/time-input"
</script>

<template>
  <Field>
    <FieldLabel>Meeting time</FieldLabel>
    <TimeInput default-value="09:30" />
  </Field>
</template>

Click the hour and type 230, then P. Press ArrowUp or ArrowDown on a part to step it.

Installation

npm install @ui-sdk/vue @ui-sdk/core

Composition

Use the following composition to build a TimeInput:

TimeInput
├── TimeInputSegment
└── TimeInputSegment

TimeInput renders a group with one TimeInputSegment for each part of the time, and the text between them.

Usage

Put the input in a Field and give it a label:

<script setup lang="ts">
import { Field, FieldLabel } from "@ui-sdk/vue/field"
import { TimeInput } from "@ui-sdk/vue/time-input"
</script>

<template>
  <Field>
    <FieldLabel>Meeting time</FieldLabel>
    <TimeInput default-value="09:30" />
  </Field>
</template>

The value is a 24-hour time like "14:30", the same as a native time input's, whatever clock the input shows. Typing, stepping and pasting work as they do in Date Input.

Clock and Seconds

The input shows the locale's clock. Set hour-cycle to 12 or 24 to choose one, and granularity to "second" to add seconds, or "hour" to show the hour alone.

<script setup lang="ts">
import { Field, FieldLabel } from "@ui-sdk/vue/field"
import { TimeInput } from "@ui-sdk/vue/time-input"
</script>

<template>
  <div data-slot="stack">
    <Field>
      <FieldLabel>12-hour clock</FieldLabel>
      <TimeInput :hour-cycle="12" default-value="18:45" />
    </Field>
    <Field>
      <FieldLabel>24-hour clock</FieldLabel>
      <TimeInput :hour-cycle="24" default-value="18:45" />
    </Field>
    <Field>
      <FieldLabel>With seconds</FieldLabel>
      <TimeInput
        granularity="second"
        :hour-cycle="24"
        default-value="18:45:30"
      />
    </Field>
  </div>
</template>

The same evening time on a 12-hour clock, a 24-hour clock and with seconds. All three submit 24-hour values.

Min and Max

min and max take times like "09:00". A time outside them is invalid: the input sets data-invalid, and its form won't submit.

A hidden input submits the time under name. Set required to need a time before the form submits, and form to the id of a form elsewhere in the page to submit with it. The Date Input form example has a time in it.

Controlled and Controller

Bind v-model:value, or drive the input with createTimeInputController(), as in Date Input.

Styling

Style it like Date Input. The AM/PM segment sets data-type="dayPeriod".

Each part has a data-slot, such as time-input-segment, and its state attributes are listed under Data Attributes.

Data Attributes

TimeInput

[data-slot="time-input"]

Attribute	What it means
`data-disabled`	Present when disabled, by its own prop or a `<fieldset>`.
`data-readonly`	Present when read-only.
`data-required`	Present when required.
`data-invalid`	Present while the time is before `min` or after `max`.
`data-empty`	Present while every segment is empty.

TimeInputSegment

[data-slot="time-input-segment"]

Attribute	What it means
`data-type`	`hourminuteseconddayPeriodliteral`The segment's unit, or `literal` for the text between segments.
`data-disabled`	Present when disabled, by its own prop or a `<fieldset>`.
`data-readonly`	Present when read-only.
`data-required`	Present when required.
`data-invalid`	Present while the time is before `min` or after `max`.
`data-empty`	Present while the segment is empty. It shows its placeholder.

API Reference

Props are the same as below, in kebab case in templates, and callbacks are events.

TimeInput

value?string | null: The value: a time like "14:30", or "14:30:15" with seconds, or null. Pass it to control the input.
defaultValue?string | null: The value it starts with, when uncontrolled, and goes back to when its form resets.
@value-change((value: string | null, details: ChangeDetails<TimeInputValueChangeReason>) => void): Runs when the value wants to change: once every segment holds something, and again with null when one is emptied. details.cancel() keeps the value.
granularity?TimeInputGranularity: The smallest unit it shows.
hourCycle?HourCycle: A 12 or 24 hour clock. Defaults to the locale's.
min?string: The earliest time, like "09:00". A time before it is invalid.
max?string: The latest time, like "17:30". A time after it is invalid.
locale?string: The language whose separators and clock it shows. Defaults to the page's.
disabled?boolean: Whether it can't be used.
readOnly?boolean: Whether the value can be seen but not changed.
required?boolean: Whether a time must be entered before its form submits.
name?string: The name the value submits under.
form?string: The id of the form it belongs to, when it isn't inside it.
controller?object: Drives it from anywhere. Create one with createTimeInputController().
debug?boolean: Logs every state change with its reason to the console, in development builds.

State

valuestring | null: The value, or null while empty or partly filled.
segmentsDateInputSegmentData[]: The segments in the order the locale shows them, with the text between them. Render one part for each.
disabledboolean: Whether it can't be used, by itself or by a <fieldset>.
readOnlyboolean: Whether the value can be seen but not changed.
invalidboolean: Whether the value is before min, after max or an unavailable date.

Reasons

input-changeEvent: Typing, pasting or dropping changed a text field's value; in a combobox it can also open or close it, or Enter keeps the typed text as the value.
step-keyKeyboardEvent: Arrow, Page Up, Page Down, Home or End stepped a slider or a number input.
pasteClipboardEvent: Files were pasted, like a screenshot, or text and tokens into a token input.
resetnone: A form reset.
restorenone: The browser restored state, like after going back, or a saved value was read back from storage.
imperativenone: A controller or api call, or a property set on a web component.

Controller

getValue()() => string | null: The value, or null while empty or partly filled.
setValue(value, options?)(value: string | null, options?: DateInputChangeOptions | undefined) => boolean: Sets the value. Returns false when it isn't a value the input can show, or when canceled.
clear(options?)(options?: DateInputChangeOptions | undefined) => boolean: Empties every segment.
focus(segment?)(segment?: string | undefined) => void: Focuses a segment, like "month", or the first one.

Events

Events get the new value first, then the details. v-model:value only updates when the change wasn't canceled.

Binding	On	Receives
`v-model:value`	`TimeInput`	The time, or null while empty or partly typed
`@value-change`	`TimeInput`	`(value, details)`: the time, or null once it's erased, and the reason

Accessibility

The root is a group, named by its Field's label or by your aria-label. Each segment is a spinbutton named by its unit, like "hour" or "AM/PM", with its value, range and text. The keys are the same as in Date Input.

Tested Behavior

Every line below is an automated test.

Each unit is a spinbutton in the locale's order.
Another locale orders the segments its own way.
Typing fills each segment, moves on and reports the date once.
A press on the box or between segments focuses the nearest segment.
A digit that can't start a longer number moves on at once.
A separator moves to the next segment.
Typing with separators over a filled date or time keeps every segment.
ArrowUp and ArrowDown step a segment and wrap around.
PageUp and PageDown take bigger steps.
Home and End go to a segment's first and last values.
ArrowLeft and ArrowRight move between segments.
Tab moves through the segments, then out.
Backspace empties a segment, then moves back.
A day past the end of a new month is moved back to its last day.
Pasting a date fills every segment.
A time takes hours, minutes and AM or PM.
A 24-hour clock has no AM or PM.
A date with a time shows its hour and minute too.
A controller sets and clears the date.
A canceled change keeps the date.
The form submits the ISO date and time under their names.
Enter submits the form with what was typed.
Resetting the form brings back the default date.
A partly filled date can't be submitted.
A required empty date can't be submitted.
A date after max is invalid.
An unavailable date is invalid.
The field's label focuses the first segment.
A read-only date takes focus but doesn't change.
A disabled date can't be focused.

Runs in React, Vue and web components.
