@nativescript/datetimepicker

A plugin that provides the UI elements DatePickerField, TimePickerField and DateTimePickerFields for picking a date and a time. The DatePickerField and TimePickerField components extend the TextField view, while the DateTimePickerFields extends the GridLayout layout container that contains instances of the DatePickerField and TimePickerField components. There is also a DateTimePicker class which provides static methods pickDate() and pickTime() that can be called to show the same dialog picker as the fields.

Installation

npm install @nativescript/datetimepicker

Use @nativescript/datetimepicker

Core

1. Register the plugin namespace with Page's xmlns attribute providing your prefix (datetime for example) and setting its value to the plugin name.

   <Page
     xmlns="http://schemas.nativescript.org/tns.xsd"
     xmlns:datetime="@nativescript/datetimepicker"
   ></Page>

2. Access the datePickerField view through the prefix.

   <Page
     xmlns="http://schemas.nativescript.org/tns.xsd"
     xmlns:datetime="@nativescript/datetimepicker"
   >
     <datetime:DatePickerField hint="select date"></datetime:DatePickerField>
     <datetime:TimePickerField hint="select time"></datetime:TimePickerField>
     <datetime:DateTimePickerFields
       hintDate="select date"
       hintTime="select time"
     ></datetime:DateTimePickerFields>
   </Page>

Angular

1. Register the plugin by adding the plugin's NativeScriptDateTimePickerModule to the imports array of the module that contains the component where you want to use the DatePickerField:

   import { NativeScriptDateTimePickerModule } from '@nativescript/datetimepicker/angular'
   
   @NgModule({
     imports: [
       NativeScriptCommonModule,
       NativeScriptDateTimePickerModule,
       // ...
     ],
     // ...
   })

2. Use DatePickerField in markup as follows:

   <DatePickerField hint="select date"></DatePickerField>
   <TimePickerField hint="select time"></TimePickerField>
   <DateTimePickerFields
     hintDate="select date"
     hintTime="select time"
   ></DateTimePickerFields>

Vue

1. Once the plugin has been installed, register it with your app project, in the main.ts file for global access.

   import DateTimePicker from '@nativescript/datetimepicker/vue'
   
   import Home from './components/Home.vue'
   
   const app = createApp(Home).use(DateTimePicker)
   
   app.start()

2. Use the DatePickerField in a template as follows:

   <DatePickerField hint="select date" />
   <TimePickerField hint="select time" />
   <DateTimePickerFields hintDate="select date" hintTime="select time" />

Svelte

Once you have installed the plugin, register the DateTimePickerFields with your app, in the app.ts file.

registerNativeViewElement(
  'dateTimePickerFields',
  () => require('@nativescript/datetimepicker').DateTimePickerFields,
)

Next, use the picker in markup by adding the dateTimePickerFields element.

<dateTimePickerFields hintDate="pick a date" hintTime="pick time"></dateTimePicker>

Set the selected date and time

To set the selected time of the TimePickerField, use the time property.

<TimePickerField time="01:00"></TimePickerField>

The DatePickerField and DateTimePickerFields components both use the date property to set their selected date(and the time for DateTimePickerFields) value.

<DatePickerField date="2019/02/24"></DatePickerField>

<DateTimePickerFields date="2019/02/24 01:00"></DateTimePickerFields>

Change the picker titles and buttons labels

To change the titles and the button labels of the picker's popups, use the pickerOkText, pickerCancelText and pickerTitle properties.

<DatePickerField
  hint="tap to choose"
  pickerOkText="Approve"
  pickerCancelText="Reject"
  pickerTitle="Confirm predefined date selection"
  pickerDefaultDate="2019/05/15"
></DatePickerField>

The DateTimePickerFields has the additional pickerTitleDate for the date picker title and the pickerTitleTime for the time picker title.

<DateTimePickerFields
  hintDate="tap to choose date"
  hintTime="tap to choose time"
  pickerOkText="Approve"
  pickerCancelText="Reject"
  pickerTitleDate="Confirm predefined date selection"
  pickerTitleTime="Confirm predefined time selection"
  pickerDefaultDate="2019/05/15 22:00"
  autoPickTime="true"
></DateTimePickerFields>

Set localization

To localize the DatePickerField and DateTimePickerFields components, use the locale property.

<DatePickerField locale="en_GB" hint="select date"></DatePickerField>
<!-- DateTimePickerFields -->
<DateTimePickerFields
  locale="de_DE"
  hintDate="datum auswählen"
  hintTime="zeit wählen"
  pickerOkText="Bestätigen"
  pickerCancelText="Stornieren"
  pickerTitleDate="Datum auswählen"
  pickerTitleTime="Zeit wählen"
></DateTimePickerFields>

Format the date and time

Aside from the default formats that are dependent on the value of the locale property, you can add your custom format that can include ordering of the date/time values and also custom text. To customize the date format, use the dateFormat property.

<DatePickerField
  date="2019/02/24"
  dateFormat="'my date': dd-MMMM-yyyy"
></DatePickerField>

The TimePickerField will determine whether to use 12 or 24 hour format (for formatting of the selected time in the field and for the values of the hour spinner) based on the selected region in the settings of the iOS device and based on the Use 24-Hour Format setting of the Android device. To change the default setting on Android, you need to use the timeFormat property and to change the setting on iOS, you need to use the locale property.

<TimePickerField
  time="16:00"
  timeFormat="h:mm a"
  locale="en_US"
></TimePickerField>

For the DateTimePickerFields picker, use the same properties( dateFormat, timeFormat and locale) for custom date and time formats.

<DateTimePickerFields
  date="2019/02/24 16:00"
  timeFormat="h:mm a"
  locale="en_US"
></DateTimePickerFields>

Set the minimum and maximum dates

To set the minimum and maximum dates, use the minDate and maxDate properties for the DatePickerField and DateTimePickerFields components.

<DatePickerField
  minDate="2020/02/02"
  maxDate="2021/02/02"
  hint="tap to select"
></DatePickerField>
<!-- DateTimePickerFields -->
<DateTimePickerFields
  minDate="2020/02/02"
  maxDate="2021/02/02"
  hintDate="tap to select date"
  hintTime="tap to select time"
></DateTimePickerFields>

Set the layout of DateTimePickerFields pickers

To lay out the picker fields in the horizontal(default) or vertical direction, use the orientation property.

<DateTimePickerFields
  hintDate="select date"
  hintTime="select time"
  orientation="vertical"
></DateTimePickerFields>

Style the pickers with CSS

You can use CSS to style the DatePickerField and the TimePickerField pickers. The same styling applies to the pickers contained in DateTimePickerFields component. The picker supports changing its colors through the following predefined CSS classes:

• date-time-picker: picker background and title text color)
• date-time-picker-spinners: background and text color of the date/time selecting spinners
• date-time-picker-buttons: background and text color of the OK/Cancel buttons
• date-time-picker-button-ok and date-time-picker-button-cancel: to provide a separate style for each button.

Note that the iOS native implementation has limited capabilities for the buttons background colors. When a button is marked as a Cancel button, its background is always white and can't be changed. If you really need a cancel button with another color, you can pass a background color through the designated cancel button class, however this will change the picker layout and place the cancel button along with the OK button and they will both have the same background color.

timepickerfield,
datepickerfield {
  padding: 12 4;
}

timepickerfield.apply-css,
datepickerfield.apply-css {
  color: #cddc39;
  background-color: #00796b;
  font-size: 20;
  font-weight: bold;
  padding: 20;
}

.date-time-picker.apply-css {
  color: #00796b;
  background-color: #cddc39;
}

.date-time-picker-spinners.apply-css {
  color: #cddc39;
  background-color: #00796b;
}

.date-time-picker-buttons.apply-css {
  color: #00796b;
}

To apply styles at runtime when opening the DateTimePicker you can do the following:

import {
  DateTimePicker,
  DateTimePickerStyle,
} from '@nativescript/datetimepicker'
import { Application, View } from '@nativescript/core'

function createPicker(args: EventData) {
  const dateTimePickerStyle = DateTimePickerStyle.create(args.object as any)

  // This example handles styling the calendar for light and dark mode of the device settings
  if (Application.systemAppearance() === 'dark') {
    // style for dark mode
    dateTimePickerStyle.buttonsBackgroundColor = new Color('#202125')
    dateTimePickerStyle.dialogBackgroundColor = new Color('#202125')
    dateTimePickerStyle.titleTextColor = new Color('#fff')
    dateTimePickerStyle.buttonsTextColor = new Color('#0067a6')
    dateTimePickerStyle.spinnersBackgroundColor = new Color('#202125')
    dateTimePickerStyle.spinnersTextColor = new Color('#fff')
  } else {
    // style for light mode
    dateTimePickerStyle.buttonsBackgroundColor = new Color('#fff')
    dateTimePickerStyle.dialogBackgroundColor = new Color('#fff')
    dateTimePickerStyle.titleTextColor = new Color('#0067a6')
    dateTimePickerStyle.buttonsTextColor = new Color('#0067a6')
    dateTimePickerStyle.spinnersBackgroundColor = new Color('#fff')
    dateTimePickerStyle.spinnersTextColor = new Color('#0067a6')
  }

  DateTimePicker.pickDate(
    {
      context: (args.object as View)._context,
      minDate: new Date((new Date() as any) - 1),
      title: 'DatePicker',
      okButtonText: 'Okay',
      cancelButtonText: 'Cancel',
      locale: 'es',
    },
    dateTimePickerStyle,
  ).then((result) => {
    // handle the result
  })
}

Create custom pickers manually

Internally DatePickerField and TimePickerField call the pickDate and pickTime methods of the DateTimePicker class which are public. You can create custom pickers by calling those methods manually. The pickDate method accepts DatePickerOptions, while the pickTime method accepts TimePickerOptions.

function onPickDateTap(args: EventData) {
  const dateToday = new Date()
  const dateTomorrow = new Date(
    dateToday.getFullYear(),
    dateToday.getMonth(),
    dateToday.getDate() + 1,
  )
  const dateNextWeek = new Date(
    dateToday.getFullYear(),
    dateToday.getMonth(),
    dateToday.getDate() + 7,
  )

  DateTimePicker.pickDate({
    context: args.object._context,
    date: dateTomorrow,
    minDate: dateTomorrow,
    maxDate: dateNextWeek,
    okButtonText: 'OK',
    cancelButtonText: 'Cancel',
    title: 'choose date',
    locale: 'en_GB',
  }).then((selectedDate) => {
    if (selectedDate) {
      this.dateText = this.getFormattedDate(selectedDate)
    }
  })
}

function onPickTimeTap(args: EventData) {
  const dateToday = new Date()
  const dateTomorrow = new Date(
    dateToday.getFullYear(),
    dateToday.getMonth(),
    dateToday.getDate() + 1,
  )
  dateTomorrow.setHours(8)
  dateTomorrow.setMinutes(0)
  DateTimePicker.pickTime({
    context: args.object._context,
    time: dateTomorrow,
    okButtonText: 'OK',
    cancelButtonText: 'Cancel',
    title: 'choose time',
    locale: 'en_GB',
    is24Hours: true,
  }).then((selectedTime) => {
    if (selectedTime) {
      this.timeText = this.getFormattedTime(selectedTime)
    }
  })
}
