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 a directive. It is done this way, because then there is 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
  • easily set styles to the component which are in line with your page theme
    • calendar (example)
    • input box and input box controls (bootstrap 4 and font-awesome example)
  • 40+ options
    • change value of any option dynamically
• well tested
  • coverage report
  • most of the codes are from the existing 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

Code examples are here.

Installation

To install this component to an external project, follow the procedure:

1. npm install angular-mydatepicker --save

2. Add AngularMyDatePickerModule import to your @NgModule as follows:

   import { BrowserModule } from '@angular/platform-browser';
   import { NgModule } from '@angular/core';
   import { FormsModule, ReactiveFormsModule } from '@angular/forms';
   import { AngularMyDatePickerModule } from 'angular-mydatepicker';
      
   @NgModule({
     declarations: [
       AppComponent
     ],
     imports: [
       BrowserModule, 
       ReactiveFormsModule, 
       FormsModule, 
       AngularMyDatePickerModule
     ],
     providers: [],
     bootstrap: [AppComponent]
   })
   export class AppModule { }

Usage

Use one of the following two options.

1. ngModel binding

In this option the ngModel binding is used.

Examples:

• bootstrap 4 and font awesome example
• own style in input box (no bootstrap)
• example application

There are two ways to initialize date or date range to the model.

Examples:

• initialize date model (single date mode)
• initialize date model (date range mode)

2. Reactive forms

In this option the value accessor of reactive forms is used.

Examples:

• reactive forms (bootstrap 4 and font awesome)
• example application

Attributes

options attribute

The options attribute is a type of IAngularMyDpOptions. It has the following optional properties.

| Option | Default | Type | Description | | :------------- | :------------- | :----| :---------- | | dateRange | false | boolean | Date picker mode (date picker or date range picker). | | inline | false | boolean | Normal mode or inline mode. If inline mode set the input box type attribute to hidden and this option to true.

locale attribute

An ISO 639-1 language code can be provided as shorthand for the following options (dayLabels, monthLabels, dateFormat, firstDayOfWeek and sunHighlight). Currently supported languages are:

| Language code | Description | | :------------- | :------------- | | en | English | | fr | French | | fr-ch | French - Switzerland | | ja | Japanese | | fi | Finnish | | es | Spanish | | hu | Hungarian | | sv | Swedish | | nl | Dutch | | ru | Russian | | uk | Ukrainian | | no | Norwegian | | tr | Turkish | | pt-br | Portuguese - Brazil | | de | German | | de-ch | German - Switzerland | | it | Italian | | it-ch | Italian - Switzerland | | pl | Polish | | my | Burmese | | sk | Slovak | | sl | Slovenian | | zh-cn | Chinese - China | | he | Hebrew | | ro | Romanian - Romania | | ca | Catalan | | id | Indonesian | | en-au | English - Australia | | am-et | Amharic | | cs | Czech | | el | Greek | | kk | Kazakh | | th | Thai | | ko-kr | Korean | | da | Danish | | lt | Lithuanian | | vi | Vietnamese | | bn | Bengali | | bg | Bulgarian | | hr | Croatian | | ar | Arabic | | is | Icelandic | | tw | Chinese - Taiwan | | lv | Latvian | | et | Estonian |

The locale options can be overridden by options attribute.

• 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.
