Installation

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

1. npm install mydaterangepicker --save

2. Add MyDateRangePickerModule import to your @NgModule like example below

   import { NgModule } from '@angular/core';
   import { BrowserModule } from '@angular/platform-browser';
   import { MyTestApp } from './my-test-app';
   import { MyDateRangePickerModule } from 'mydaterangepicker';
   
   @NgModule({
       imports:      [ BrowserModule, MyDateRangePickerModule ],
       declarations: [ MyTestApp ],
       bootstrap:    [ MyTestApp ]
   })
   export class MyTestAppModule {}
   

3. If you are using systemjs package loader add the following mydaterangepicker properties to the System.config:

   (function (global) {
       System.config({
           paths: {
               'npm:': 'node_modules/'
           },
           map: {
               // Other components are here...
   
               'mydaterangepicker': 'npm:mydaterangepicker/bundles/mydaterangepicker.umd.js'
           },
           packages: {
           }
       });
   })(this);
   

Usage

Use one of the following three options.

1. ngModel binding

In this option the ngModel binding is used. Here is an example application. It shows how to use the ngModel.

To use ngModel define the application class as follows:

import {IMyDrpOptions} from 'mydaterangepicker';
// other imports here...

export class MyTestApp {

    myDateRangePickerOptions: IMyDrpOptions = {
        // other options...
        dateFormat: 'dd.mm.yyyy',
    };

    // For example initialize to specific date (09.10.2018 - 19.10.2018). It is also possible
    // to set initial date range value using the selDateRange attribute.
    private model: any = {beginDate: {year: 2018, month: 10, day: 9},
                             endDate: {year: 2018, month: 10, day: 19}};

    constructor() { }
}

Add the following snippet inside your template:

<form #myForm="ngForm" novalidate>
    <my-date-range-picker name="mydaterange" [options]="myDateRangePickerOptions"
                    [(ngModel)]="model" required></my-date-range-picker>
</form>

2. Reactive forms

In this option the value accessor of reactive forms is used. Here is an example application. It shows how to use the formControlName.

To use reactive forms define the application class as follows:

import {IMyDrpOptions} from 'mydaterangepicker';
// other imports here...

export class MyTestApp implements OnInit {

    myDateRangePickerOptions: IMyDrpOptions = {
        // other options...
        dateFormat: 'dd.mm.yyyy',
    };

    private myForm: FormGroup;

    constructor(private formBuilder: FormBuilder) { }

    ngOnInit() {
        this.myForm = this.formBuilder.group({
            // Empty string means no initial value. Can be also specific date range for example:
            // {beginDate: {year: 2018, month: 10, day: 9}, endDate: {year: 2018, month: 10, day: 19}}
            // which sets this date range to initial value. It is also possible to set initial
            // value using the selDateRange attribute.

            myDateRange: ['', Validators.required]
            // other controls are here...
        });
    }

    setDateRange(): void {
        // Set date range (today) using the patchValue function
        let date = new Date();
        this.myForm.patchValue({myDateRange: {
            beginDate: {
                year: date.getFullYear(),
                month: date.getMonth() + 1,
                day: date.getDate()
            },
            endDate: {
                year: date.getFullYear(),
                month: date.getMonth() + 1,
                day: date.getDate()
            }
        }});
    }

    clearDateRange(): void {
        // Clear the date range using the patchValue function
        this.myForm.patchValue({myDateRange: ''});
    }
}

Add the following snippet inside your template:

<form [formGroup]="myForm" novalidate>
    <my-date-range-picker name="mydaterange" [options]="myDateRangePickerOptions"
                    formControlName="myDateRange"></my-date-range-picker>
  <!-- other controls are here... -->
</form>

3. Callbacks

In this option the mydaterangepicker sends data back to host application using callbacks. Here is an example application. It shows how to use callbacks.

To use callbacks define the application class as follows:

import {IMyDrpOptions, IMyDateRangeModel} from 'mydaterangepicker';
// other imports here...

export class MyTestApp {

    myDateRangePickerOptions: IMyDrpOptions = {
        // other options...
        dateFormat: 'dd.mm.yyyy',
    };

    constructor() { }

    // dateRangeChanged callback function called when the user apply the date range. This is
    // mandatory callback in this option. There are also optional inputFieldChanged and
    // calendarViewChanged callbacks.
    onDateRangeChanged(event: IMyDateRangeModel) {
        // event properties are: event.beginDate, event.endDate, event.formatted,
        // event.beginEpoc and event.endEpoc
    }
}

Add the following snippet inside your template:

<my-date-range-picker [options]="myDateRangePickerOptions"
                   (dateRangeChanged)="onDateRangeChanged($event)"></my-date-range-picker>

Attributes

options attribute
