How can I create a multi-date-picker using ng-bootstrap date picker?
I have based my approach on the datepicker-range example from ng-bootstrap. You can view the final code at: https://stackblitz.com/edit/angular-he7fsp
Essentially, the key is to store selected dates in an array and modify the custom-day template to display the selected dates differently.
The structure of multi-date-picker.html closely resembles that of the ng-bootstrap datepicker range.
<!-- we do not use (select)="onDateSelection($event)"-->
<ngb-datepicker #dp [displayMonths]="2" [dayTemplate]="t">
</ngb-datepicker>
<ng-template #t let-date="date" let-focused="focused">
<!--we utilize the (click) event to pass the event and the date-->
<span class="custom-day" (click)="onDateSelection($event,date)"
[class.focused]="focused"
[class.range]="isFrom(date) || isTo(date) || isInside(date) || isHovered(date)"
[class.faded]="isHovered(date) || isInside(date)"
<!--add a class.selected if the date belongs to our selected dates -->
[class.selected]="isDateSelected(date)"
(mouseenter)="hoveredDate = date"
(mouseleave)="hoveredDate = null">
{{ date.day }}
</span>
</ng-template>
The code may seem intricate, but it's relatively straightforward. I've added functions like isDateSelected, addRangeDate, and addDate. Additionally, I modified the onDateSelection function to consider when the user presses the Ctrl key.
import {Component,Input,Output,EventEmitter} from '@angular/core';
import {NgbDateStruct, NgbCalendar} from '@ng-bootstrap/ng-bootstrap';
// Utility functions for date manipulation
@Component({
selector: 'ngb-multi-date-picker',
templateUrl: 'multi-date-picker.html',
styles: [`
.custom-day {
text-align: center;
padding: 0.185rem 0.25rem;
display: inline-block;
height: 2rem;
width: 2rem;
}
.custom-day.range, .custom-day:hover {
background-color: rgb(2, 117, 216);
color: white;
}
.custom-day.faded {
background-color: rgba(2, 117, 216, 0.5);
}
.custom-day.selected{
background-color: rgba(255, 255, 0, .5);
}
`]
})
export class MultiDatePicker {
// Class implementation omitted for brevity
}
To use this multi-date-picker component:
<ngb-multi-date-picker [datesSelected]="datesSelected"
(datesSelectedChange)="change($event)"></ngb-multi-date-picker>
In your AppComponent, you would have:
export class AppComponent {
datesSelected:NgbDateStruct[]=[];
change(value:NgbDateStruct[])
{
this.datesSelected=value;
}
