Tips for unveiling and concealing the ng-bootstrap datepicker using custom triggers and events

At the moment, I am utilizing:

ng-bootstrap 1.0.0-alpha.24
angular/core 4.0.0
bootstrap 4.0.0-alpha.6

I am curious to know if anyone has a solution on how to automatically close the datepicker when focus is lost or another datepicker is opened.

Additionally, I am wondering if it's feasible to close the datepicker in the component code using TypeScript.

If possible, could someone provide either a functional plunker or a code snippet?

My current setup looks like this:

<div class="input-group">
    <input class="rect-border full-width"
           placeholder="YYMMDD"
           [(ngModel)]="selectedDate"
           ngbDatepicker
           #datePickerInput="ngbDatepicker"
           (keydown.arrowup)="incrementDate()"
           (keydown.arrowdown)="decrementDate()"
           (ngModelChange)="validate('modelChanged')"
           (blur)="validate(null)"
           [disabled]="disabled"
           [ngClass]="{'input-required': required, 'normal-color': valid, 'picker-disabled': disabled}">

    <div class="input-group-addon rect-border"
         (click)="disabled ? true : datePickerInput.toggle()"
         [ngClass]="{'picker-button-disabled': disabled}">
        <img src="assets/img/calendar-icon.svg" class="datpickerToggle"/>
    </div>
</div>

I've been researching for quite some time and I'm fairly new to Angular and related technologies.

Thank you in advance for any assistance!

Update:

Potential Solution:

Several helpful solutions were shared. I also discovered that by using the NgbInputDatepicker class, I can successfully close the datepicker (previously I only used NgbDatepicker).

@ViewChild('datePickerInput') datePicker: NgbInputDatepicker;

this.datePicker.close();

Answer №1

Take control of your datepicker directly from your HTML code

For example:

<div class="input-group">
    <input class="rect-border full-width"
           placeholder="YYMMDD"
           [(ngModel)]="selectedDate"
           ngbDatepicker
           #datePickerInput="ngbDatepicker"
           (keydown.arrowup)="incrementDate()"
           (keydown.arrowdown)="decrementDate()"
           (ngModelChange)="validate('modelChanged')"
           (blur)="validate(null)"
           [disabled]="disabled"
           [ngClass]="{'input-required': required, 'normal-color': valid, 'picker-disabled': disabled}">

    <div class="input-group-addon rect-border"
         (click)="disabled ? true : datePickerInput.toggle()"
         [ngClass]="{'picker-button-disabled': disabled}">
        <img src="assets/img/calendar-icon.svg" class="datpickerToggle"/>
    </div>
</div>

<div (click)="datePickerInput.open()"></div>

<span (click)="datePickerInput.close()"></span>

When working with TypeScript, a simple way to control the visibility of a datepicker component is by defining a variable called datepickerVisibility. You can then use *ngIf in your template to conditionally show or hide the datepicker. Here's an example:

Template:

<datepicker *ngIf="datepickerVisibility" [ngModel]="date"> </datepicker>

Component:

private datepickerVisibility: boolean = false; 
            // Show the datepicker 
            showDatepicker() {
                 this.datepickerVisibility = true;
            }

To achieve the same functionality using jQuery, you'll need to include the jQuery script in your index.html file and then utilize it in your TypeScript component like this:

declare let jQuery: any;

@Component({
    moduleId: module.id,
    selector: 'test',
    templateUrl: 'template.html',
    styleUrls: ['test.css'],
})
export class TestComponent {
   constructor() {}

    public toggleDatepicker() {
        jQuery("#datepicker01").toggle();
   }
 }

Don't forget to assign the id "datepicker01" to your datepicker div element in the template file:

<div id="datepicker01" ...>

   }
 }

I encountered a similar issue where I needed to toggle a datepicker within a custom component without relying on jQuery or HTML calls. While the solutions provided were helpful for most cases, they didn't suit my specific requirements.

Here's how I tackled the problem:

Firstly, I included a reference to the datepicker input using ViewChild in the *.component.ts file:

  @ViewChild('d', {static: true}) d;

This reference corresponds to the identifier of the datepicker in the HTML:

<input (dateSelect)="dateSelected($event)" class="form-control" (focus)='d.toggle()' placeholder="yyyy-mm-dd" name="d"
  [ngModelOptions]="{standalone: true}" [(ngModel)]="date" ngbDatepicker #d="ngbDatepicker">

To toggle the datepicker, I created a method within the component:

toggle() {
  this.d.toggle();
}

This allows other components to call the toggle() function from this component to toggle the datepicker, as shown below:

In HTML:

<app-custom-datepicker #date></app-custom-date-picker>

In the .ts file:

@ViewChild('date', {static: true}) date;
.
.
.
this.date.toggle();
