Description

Highly configurable Angular datepicker and date range picker. Basic idea to create this library was to make it as configurable as possible. The library is implemented as an attribute directive. It is done this way because then you have more choices to configure it.

Online demo is here

Main features

  • no dependencies to other libraries
  • currently localized to 45 languages
  • datepicker
  • date range picker
  • popup mode
  • inline mode
  • supports keyboard
  • awesome configuration possibilities
  • well tested
    • coverage report
    • most of the codes are from my old libraries which are widely used

Project

This project was generated with Angular CLI version 7.3.8. The library is tested with Angular version 7.2.0.

Source code of the component is in the projects/angular-mydatepicker/src folder.

Code examples

  • a new locale data will be added to this file. If you want to add a new locale create a pull request.

Here is an example on how to use the locale attribute.

Try locales here (last datepicker on the page).

defaultMonth attribute

Visible month/year when calendar is opened:

  • If date is already selected => calendar opens to the month and year of the selected date
    • In date range mode => calendar opens to the month and year of the selected begin date
  • If the defaultMonth is set => calendar opens to the month and year specified in the the defaultMonth attribute
  • If none of above => calendar opens to the month and year of current date

Value of the defaultMonth attribute can be:

  • IMyDefaultMonth object. The value of defMonth property can be a string which contain year number and month number separated by delimiter. The delimiter can be any special character. For example: 08-2019 or 08/2019.
  • a string which contain year number and month number separated by delimiter. The delimiter can be any special character. For example: 08-2019 or 08/2019.

Example of the defaultMonth attribute is here.

Functions

You can can call functions of the directive. Define local variable to input field like below:

<input angular-mydatepicker name="mydate" [(ngModel)]="model" 
    [options]="myOptions" #dp="angular-mydatepicker"/>

The #dp="angular-mydatepicker" defines the local variable named dp. You can use it to call functions of the directive for example (click)="dp.openCalendar()".

openCalendar function

Opens the calendar. Example of the openCalendar function is here.

closeCalendar function

Closes the calendar. Example of the closeCalendar function is here.

toggleCalendar function

Closes the calendar if it is open and opens the calendar if it is closed. Example of the toggleCalendar function is here.

clearDate function

Clears the date from the input box and model. Example of the clearDate function is here.

isDateValid function

Returns true if the date in the input box is valid. Otherwise it returns false. This function also calls the inputFieldChanged callback. Example of the isDateValid function is here.
