Form Datepicker

<b-form-datepicker> is a BootstrapVue custom date picker input form control, which provides full WAI-ARIA compliance and internationalization support.

As a form control wrapper component for the <b-calendar> component, it provides additional validation state presentation and a compact interface. Native HTML5 date inputs vary in presentation, accessibility, and in some instances are not supported by all browsers. <b-form-datepicker> provides a consistent and accessible interface across all browser platforms and devices.

The <b-form-datepicker> component was introduced in BootstrapVue release v2.5.0.

<template>
  <div>
    <label for="example-datepicker">Choose a date</label>
    <b-form-datepicker id="example-datepicker" v-model="value" class="mb-2"></b-form-datepicker>
    <p>Value: '{{ value }}'</p>
  </div>
</template>

<script>
  export default {
    data() {
      return {
        value: ''
      }
    }
  }
</script>

<!-- b-form-datepicker.vue -->

<b-form-datepicker> supports many of the props available on <b-calendar> as well as some of the props available on <b-dropdown>.

v-model return value

By default, <b-form-datepicker> returns dates as a string in the YYYY-MM-DD format, which is the same format returned by native browser <input type="date"> controls. You can have <b-form-datepicker> return a Date object (with no time portion) as the v-model value instead by setting the value-as-date prop.

If no date is selected, <b-form-datepicker> returns an empty string '', or returns null if the value-as-date prop is set.

Note that when value-as-date prop is set, the returned Date object will be in the browser's default timezone.

If <b-form-datepicker> has a value set for the name prop, a hidden input will be created which will have its name attribute set to the value of the name prop, and the value attribute will be set to the selected date as a YYYY-MM-DD string. This will allow the <b-form-datepicker> selected value to be submitted via native browser form submission.

Disabled and readonly states

Setting the disabled prop will remove all interactivity of the <b-form-datepicker> component.

Setting the readonly prop will disable selecting a date, but will keep the component interactive, allowing for date navigation. The v-model will not be updated in the readonly state.

For disabling specific dates or setting minimum and maximum date limits, refer to the Date constraints section.

<template>
  <div>
    <b-form-group label="Select date picker interactive state">
      <b-form-radio-group v-model="state" aria-controls="ex-disabled-readonly">
        <b-form-radio value="disabled">Disabled</b-form-radio>
        <b-form-radio value="readonly">Readonly</b-form-radio>
        <b-form-radio value="normal">Normal</b-form-radio>
      </b-form-radio-group>
    </b-form-group>
    <b-form-datepicker id="ex-disabled-readonly" :disabled="disabled" :readonly="readonly"></b-form-datepicker>
  </div>
</template>

<script>
  export default {
    data() {
      return {
        state: 'disabled'
      }
    },
    computed: {
      disabled() {
        return this.state === 'disabled'
      },
      readonly() {
        return this.state === 'readonly'
      }
    }
  }
</script>

<!-- b-form-datepicker-disabled-readonly.vue -->

Date constraints

Minimum and maximum dates

Restrict the calendar range via the min and max props. The props accept a date string in the format of YYYY-MM-DD or a Date object.

<template>
  <div>
    <b-form-datepicker v-model="value" :min="min" :max="max" locale="en"></b-form-datepicker>
  </div>
</template>

<script>
  export default {
    data() {
      const now = new Date()
      const today = new Date(now.getFullYear(), now.getMonth(), now.getDate())
      // 15th two months prior
      const minDate = new Date(today)
      minDate.setMonth(minDate.getMonth() - 2)
      minDate.setDate(15)
      // 15th in two months
      const maxDate = new Date(today)
      maxDate.setMonth(maxDate.getMonth() + 2)
      maxDate.setDate(15)

      return {
        value: '',
        min: minDate,
        max: maxDate
      }
    }
  }
</script>

<!-- b-form-datepicker-min-max.vue -->

Disabling dates

If you need to disable specific dates within the date picker, specify a function reference to the date-disabled-fn prop. The function is passed two arguments:

  • ymd The date as a YYYY-MM-DD string
  • date The date as a Date object

The function should either return true if the date cannot be selected (disabled), or false if the date can be selected (enabled). Note that the function cannot be asynchronous, and should return a value as quickly as possible.

<template>
  <div>
    <b-form-datepicker v-model="value" :date-disabled-fn="dateDisabled" locale="en"></b-form-datepicker>
  </div>
</template>

<script>
  export default {
    data() {
      return {
        value: ''
      }
    },
    methods: {
      dateDisabled(ymd, date) {
        // Disable weekends (Sunday = `0`, Saturday = `6`) and
        // disable days that fall on the 13th of the month
        const weekday = date.getDay()
        const day = date.getDate()
        // Return `true` if the date should be disabled
        return weekday === 0 || weekday === 6 || day === 13
      }
    }
  }
</script>

<!-- b-form-datepicker-disabled-dates.vue -->

Note the min and max date constraints are evaluated first, before date-disabled-fn.

Validation states

<b-form-datepicker> supports invalid and valid styling via the boolean state prop. Setting state to boolean false will style the input as invalid, while setting it to boolean true will style it as valid. Setting state to null will not show any validation state styling (the default).

<template>
  <div>
    <label for="datepicker-invalid">Choose a date (invalid style)</label>
    <b-form-datepicker id="datepicker-invalid" :state="false" class="mb-2"></b-form-datepicker>
    <label for="datepicker-valid">Choose a date (valid style)</label>
    <b-form-datepicker id="datepicker-valid" :state="true"></b-form-datepicker>
  </div>
</template>

<!-- b-form-datepicker-invalid-valid.vue -->

Note that native browser validation is not available with <b-form-datepicker>.

Styling

Variants

The selected date button (background color) defaults to the 'primary' theme variant. You can change this to any of the Bootstrap v4 theme variant colors: 'secondary', 'success', 'danger', 'warning', 'info', etc, via the selected-variant prop.

Today's date will also be highlighted (text color) using the same variant as the selected date by default. To specify a different theme color to use for today's date, use the today-variant prop.

To disable highlighting of today's date altogether, set the no-highlight-today prop.

Control sizing

Fancy a smaller or larger <b-form-datepicker> control? Set the size prop to 'sm' for a smaller form control, or 'lg' for a larger form form control. Note this does not affect the size of the popup calendar dialog.

<template>
  <div>
    <label for="datepicker-sm">Small date picker</label>
    <b-form-datepicker id="datepicker-sm" size="sm" local="en" class="mb-2"></b-form-datepicker>
    <label for="datepicker-lg">Large date picker</label>
    <b-form-datepicker id="datepicker-lg" size="lg" local="en"></b-form-datepicker>
  </div>
</template>

<!-- b-form-datepicker-sizes.vue -->

Placeholder

Add custom placeholder text to the control, when no date is selected, via the placeholder prop. If a placeholder is not provided, the value of the label-no-date-selected prop is used.

<template>
  <div>
    <label for="datepicker-placeholder">Date picker with placeholder</label>
    <b-form-datepicker id="datepicker-placeholder" placeholder="Choose a date" local="en"></b-form-datepicker>
  </div>
</template>

<!-- b-form-datepicker-placeholder.vue -->

Optional controls

Add optional control buttons to the bottom of the calendar popup via the props today-button, reset-button and close-button.

  • The today button selects today's date
  • The reset button either clears the selected date, or sets the date to the value of the prop reset-value (if provided)
  • The close button closes the calendar popup

By default, clicking on the today or reset button will also close the calendar popup, unless the prop no-close-on-select is set.

<template>
  <div>
    <label for="datepicker-buttons">Date picker with optional footer buttons</label>
    <b-form-datepicker
      id="datepicker-buttons"
      today-button
      reset-button
      close-button
      locale="en"
    ></b-form-datepicker>
  </div>
</template>

<!-- b-form-datepicker-buttons.vue -->

The text for the optional buttons can be set via the label-today-button, label-reset-button, and the label-close-button props. Due to the limited width of the footer section, it is recommended to keep these labels short.

Note that the Set Today button may not set the control today's date, if today's date is outside of the min or max date range restrictions. In the case it is outside of the range, it will set to either min or max (depending on which is closes to today's date).

Use the dropdown props right, dropup, dropright, dropleft, no-flip, and offset to control the positioning of the popup calendar.

Refer to the <b-dropdown> documentation for details on the effects and usage of these props.

Initial open calendar date

By default, when no date is selected, the calendar view will be set to the current month (or the min or max date if today's date is out of range of min or max) when opened. You can change this behaviour by specifying a date via the initial-date prop. The initial date prop will be used to determine the calendar month to be initially presented to the user. It does not set the component's value.

Dark mode

Want a fancy popup with a dark background instead of a light background? Set the dark prop to true to enable the dark background.

Button only mode

v2.7.0+

Fancy just a button that launches the date picker dialog, or want to provide your own optional text input field? Use the button-only prop to render the datepicker as a dropdown button. The formatted date label will be rendered with the class sr-only (available only to screen readers).

In the following simple example, we are placing the datepicker (button only mode) as an append to a <b-input-group>:

<template>
  <div>
    <label for="example-input">Choose a date</label>
    <b-input-group class="mb-3">
      <b-form-input
        id="example-input"
        v-model="value"
        type="text"
        placeholder="YYYY-MM-DD"
      ></b-form-input>
      <b-input-group-append>
        <b-form-datepicker
          v-model="value"
          button-only
          right
          locale="en-US"
          aria-controls="example-input"
        ></b-form-datepicker>
      </b-input-group-append>
    </b-input-group>
    <p>Value: '{{ value }}'</p>
  </div>
</template>

<script>
  export default {
    data() {
      return {
        value: ''
      }
    }
  }
</script>

<!-- b-form-datepicker-button-only.vue -->

Control the size of the button via the size prop, and the button variant via the button-variant prop.

Date string format

v2.6.0+

To change format options of the displayed date text inside the component, e.g. in the header or placeholder, set the date-format-options prop to an object containing the requested format properties for the Intl.DateTimeFormat object (see also Internationalization).

<template>
  <div>
    <label for="datepicker-dateformat1">Custom date format</label>
    <b-form-datepicker
      id="datepicker-dateformat1"
      :date-format-options="{ year: 'numeric', month: 'short', day: '2-digit', weekday: 'short' }"
      locale="en"
    ></b-form-datepicker>

    <label class="mt-3" for="datepicker-dateformat2">Short date format</label>
    <b-form-datepicker
      id="datepicker-dateformat2"
      :date-format-options="{ year: 'numeric', month: 'numeric', day: 'numeric' }"
      locale="en"
    ></b-form-datepicker>
  </div>
</template>

<!-- b-form-datepicker-dateformat.vue -->

The following table summarizes the valid options for each format property:

Property Possible values
year 'numeric', or '2-digit'
month 'numeric', '2-digit', 'long', 'short', or 'narrow'
day 'numeric', or '2-digit'
weekday 'long', 'short', or 'narrow'

Notes:

  • Leaving out certain options may affect the formatted text string, e.g. the weekday
  • The formatted value will vary according to the resolved locale. Some locales may not support the 'narrow' format and will fall back to 'short' or long' (if 'short' is not available)
  • year, month and day will always be shown. If you need to leave out a value, set the property to undefined, although this is highly discouraged for accessibility reasons

Internationalization

Internationalization of the date picker's calendar is provided via Intl.DateTimeFormat, except for labels applied to elements of the calendar control (aria-labels, selected status, and help text). You must provide your own translations for these labels. The available locales will be browser dependant (not all browsers support all locales)

By default <b-form-datepicker> will use the browser's default locale, but you can specify the locale (or locales) to use via the locale prop. The prop accepts either a single locale string, or an array of locale strings (listed in order of preferred locale).

The calendar starts the week on Sunday. This can be changed by setting the start-weekday prop to a number in the range of 0 to 6 where 0 represents Sunday, 1 for Monday, up to 6 for Saturday.

<template>
  <div>
    <label for="example-locales">Locale:</label>
    <b-form-select id="example-locales" v-model="locale" :options="locales" class="mb-2"></b-form-select>

    <label for="example-weekdays">Start weekday:</label>
    <b-form-select id="example-weekdays" v-model="weekday" :options="weekdays" class="mb-2"></b-form-select>

</script>

<!-- b-form-datepicker-i18n.vue -->

You can listen to for the context event to determine the locale and directionality that the calendar has resolved to.

Refer to the <b-calendar> documentation for additional details.

Accessibility

The popup calendar supports the same keyboard controls as <b-calendar>, along with the following:

  • ESC will close the popup calendar without selecting a date

When internationalizing the datepicker, it is important to also update the label-* props with appropriate translated strings, so that international screen reader users will hear the correct prompts and descriptions.

Refer to the <b-calendar> documentation for additional details.

Implementation notes

<b-form-datepicker> is based upon the components <b-calendar> and <b-dropdown>.

<b-form-datepicker> uses Bootstrap's margin, padding, border, and flex utility classes, along with button (btn-*) classes, and the form-control* (plus validation) classes.

BootstrapVue's Custom SCSS/CSS is also required for proper styling of the date picker and calendar.
