ngx-mydatepicker

Angular date picker

Description

Angular attribute directive date picker. Compatible Angular2+.

There is similar date picker here, but difference between these two is that with the ngx-mydatepicker you can define the style of input box, calendar and clear buttons.

Online demo of bootstrap styled input box and glyphicons is here

Installation

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

npm install ngx-mydatepicker --save

Add MyDatePickerModule 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 { NgxMyDatePickerModule } from 'ngx-mydatepicker';

@NgModule({
    imports:      [ BrowserModule, NgxMyDatePickerModule.forRoot() ],
    declarations: [ MyTestApp ],
    bootstrap:    [ MyTestApp ]
})
export class MyTestAppModule {}

If you are using systemjs package loader add the following ngx-mydatepicker properties to the System.config:

(function (global) {
    System.config({
        paths: {
            'npm:': 'node_modules/'
        },
        map: {
            // Other components are here...

            'ngx-mydatepicker': 'npm:ngx-mydatepicker/bundles/ngx-mydatepicker.umd.min.js'
        },
        packages: {
        }
    });
})(this);

Usage

Use one of the following two 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 {INgxMyDpOptions, IMyDateModel} from 'ngx-mydatepicker';
// other imports here...

export class MyTestApp {

    myOptions: INgxMyDpOptions = {
        // other options...
        dateFormat: 'dd.mm.yyyy',
    };

    // Initialized to specific date (09.10.2018)
    model: any = { date: { year: 2018, month: 10, day: 9 } };

    constructor() { }

    // optional date changed callback
    onDateChanged(event: IMyDateModel): void {
        // date selected
    }
}

Add the following snippet inside your template:

<!-- input box styling is bootstrap 3.3.7 -->
<form>
    <div class="input-group">
        <input class="form-control" style="float:none" placeholder="Select a date" ngx-mydatepicker name="mydate"
               [(ngModel)]="model" [options]="myOptions" #dp="ngx-mydatepicker" (dateChanged)="onDateChanged($event)"/>

        <span class="input-group-btn">
            <button type="button" class="btn btn-default" (click)="dp.clearDate()">
                <i class="glyphicon glyphicon-remove"></i>
            </button>
            <button type="button" class="btn btn-default" (click)="dp.toggleCalendar()">
                <i class="glyphicon glyphicon-calendar"></i>
            </button>
        </span>
    </div>
</form>

There are two ways to set an initial date to the model.

Initialize with the IMyDate object:

// Initialized to specific date (09.10.2018)
model: any = { date: { year: 2018, month: 10, day: 9 } };

Initialize with the JS date object:

// Initialized to today
model: any = { jsdate: new Date() };

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 {INgxMyDpOptions} from 'ngx-mydatepicker';
// other imports here...

export class MyTestApp implements OnInit {

    myOptions: INgxMyDpOptions = {
        // other options...
        dateFormat: 'dd.mm.yyyy',
    };

    private myForm: FormGroup;

    constructor(private formBuilder: FormBuilder) { }

    ngOnInit() {
        this.myForm = this.formBuilder.group({
            // Empty string or null means no initial value. Can be also specific date for
            // example: {date: {year: 2018, month: 10, day: 9}} which sets this date to initial
            // value.

            myDate: [null, Validators.required]
            // other controls are here...
        });
    }

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

    clearDate(): void {
        // Clear the date using the patchValue function
        this.myForm.patchValue({myDate: null});
    }
}

Add the following snippet inside your template:

<!-- input box styling is bootstrap 3.3.7 -->
<form [formGroup]="myForm" (ngSubmit)="onSubmit()" novalidate>
    <div class="input-group">
        <input class="form-control" style="float:none" placeholder="Select a date" ngx-mydatepicker name="myDate"
               formControlName="myDate" [options]="myOptions" #dp="ngx-mydatepicker"/>

        <span class="input-group-btn">
            <button type="button" class="btn btn-default" (click)="dp.clearDate()">
                <i class="glyphicon glyphicon-remove"></i>
            </button>
            <button type="button" class="btn btn-default" (click)="dp.toggleCalendar()">
                <i class="glyphicon glyphicon-calendar"></i>
            </button>
        </span>
    </div>

    <div class="btnGroup">
        <button class="button" type="submit" [disabled]="myForm.controls.myDate.errors">Submit</button>
        <p class="error" *ngIf="myForm.controls.myDate.errors">Date is required!</p>
    </div>
</form>

Functions

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

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

This #dp="ngx-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. For example:

<button type="button" (click)="dp.openCalendar()">Open</button>

closeCalendar function

Closes the calendar. For example:

<button type="button" (click)="dp.closeCalendar()">Close</button>

toggleCalendar function

Closes the calendar if it is open and opens the calendar if it is closed. For example:

<button type="button" (click)="dp.toggleCalendar()">Toggle</button>

clearDate function

Clears the date from the input box and model. For example:

<button type="button" (click)="dp.clearDate()">Clear</button>

isDateValid function

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

<input ngx-mydatepicker [(ngModel)]="model" [options]="myDatePickerOptions" #dp="ngx-mydatepicker"/>

@ViewChild('dp') ngxdp: NgxMyDatePickerDirective;

checkDateValidity(): void {
    let valid: boolean = this.ngxdp.isDateValid();
    console.log('Valid date in the input box: ', valid);
}
