angular 2 ng-bootstrap datepicker popup

Question

Hi I am investigating on ng-bootstrap datepicker. I looked at the demo code and was able to get it to work in my application.

However, if I added more than 1 datepicker input tags, only one is working. Below are the code I created. I tried to change the #d to #d1 and #d2 (also change the toggle() part) and the page spits out errors.

<div class="input-group">
    <input class="form-control" placeholder="yyyy-mm-dd" name="dp" [(ngModel)]="newItem.EndTime"  ngbDatepicker #d="ngbDatepicker" required>
    <div class="input-group-addon" (click)="d.toggle()" >
        <i class="fa fa-calendar" aria-hidden="true"></i>
    </div>
</div>

<div class="input-group">
    <input class="form-control" placeholder="yyyy-mm-dd" name="dp" [(ngModel)]="newItem.StartTime"  ngbDatepicker #d="ngbDatepicker" required>
    <div class="input-group-addon" (click)="d.toggle()" >
        <i class="fa fa-calendar" aria-hidden="true"></i>
    </div>
</div>

I also tried to wrap it with a component and it allowed me to have multiple datepicker instance for different properties. However, it didn't seem to pass the value back to the parent component.

new.campaign.html

<div class="row col-md-12 col-lg-12">
    <div class="col-md-4 col-lg-4">
        <label for="campaignStartTime">Start Time</label>
        <datepicker-popup [(model)]="newItem.StartTime" (modelChange)="updateDate($event)" [required]="true" id="campaignStartTime"></datepicker-popup>
    </div>
</div>

datepicker-popup.component.ts

import {Component, Input, Output, EventEmitter} from '@angular/core';
    @Component({
selector: 'datepicker-popup',
templateUrl: 'app/campaign/datepicker-popup.html'
    })
    export class DatepickerPopupComponent {
    @Input()
    model:any;
    @Input()
    id:string;
    @Input()
    required:boolean=false;
    @Output()
    modelChange: EventEmitter<any> = new EventEmitter();

    constructor(){    }
    updateModel(){
    let date = this.model;
    date = '12/22/2016'
    this.modelChange.emit(date);
    }
    }

datepicker-popup.html

<div class="input-group">
    <input class="form-control" placeholder="yyyy-mm-dd" name="dp [(ngModel)]="model"  (change)="updateModel()" ngbDatepicker #d="ngbDatepicker" required>
    <div class="input-group-addon" (click)="d.toggle()" >
        <i class="fa fa-calendar" aria-hidden="true"></i>
    </div>
</div>

Can someone point me to the right direction to solve the issue?

Solution

I tried to change the #d to #d1 and #d2 (also chancge the toggle() part) and the page spits out errors.

There must be something specific to your application going on since this is the right approach. A working code snippet:

 <div class="input-group">
        <input class="form-control" placeholder="yyyy-mm-dd" name="dp1" [(ngModel)]="newItem.EndTime"  ngbDatepicker #d1="ngbDatepicker" required>
        <div class="input-group-addon" (click)="d1.toggle()" >
            <i class="fa fa-calendar" aria-hidden="true"></i>
        </div>
    </div>

    <div class="input-group">
        <input class="form-control" placeholder="yyyy-mm-dd" name="dp2" [(ngModel)]="newItem.StartTime"  ngbDatepicker #d2="ngbDatepicker" required>
        <div class="input-group-addon" (click)="d2.toggle()" >
            <i class="fa fa-calendar" aria-hidden="true"></i>
        </div>
    </div>

And the live example in plunker: https://plnkr.co/edit/ZC3dOX9anbbNUMPEEd5W?p=preview

Verify that you've got unique input names and that you use unique variable names pointing to a directive instance (#d1, #d2 etc.). If you still face problems reproduce it in the plunker I've linked and open an issue in https://github.com/ng-bootstrap/ng-bootstrap

Thank you for your response. I tried it again and this time it works! It must be the late night and some odd thing going on at the time. Thank you!!!!

How for this will be feasible for reactive forms?
