How to detect date selection in ng-bootstrap Datepicker on input field?

问题

We use the ng-bootstrap Datepicker as Directive in our project:

<input class="form-control"
         name="dp" ngbDatepicker #d="ngbDatepicker" (blur)="d.close()" [(ngModel)]="model"
         (ngModelChange)="onDateSelected()">

The current behaviour is that onDateSelected() is called when a date in the datepicker is selected, as well as every time a change is made to the input field.

The desired behaviour is that onDateSelected() is called whenever the user clicks on a date in the datepicker or moves the cursor out of the <input> (i.e. blur).

My approach was to change (ngModelChange) to (blur):

<input class="form-control"
         name="dp" ngbDatepicker #d="ngbDatepicker" (blur)="d.close(); onDateSelected()"
         [(ngModel)]="model">

but this leads to onDateSelected() not being called, when a date is selected from the datepicker - which kinda makes sense, because the cursor is not inside the <input>. However, I could not find some sort of dateSelected-Event when searching the ng-bootstrap docs on which I could call onDateSelected():

<input class="form-control"
         name="dp" ngbDatepicker #d="ngbDatepicker" (blur)="d.close(); onDateSelected()"
/* missing -> */ (dateSelected)="onDateSelected()" /* <- */ [(ngModel)]="model">

Is there something I miss? Or maybe another way to implement this behaviour? I can't think of being the only one with this requirement...

Meanwhile, the issue has been closed and there will be a (dateSelect) event in 1.1.0: https://github.com/ng-bootstrap/ng-bootstrap/pull/2254

回答2:

<input class="form-control"
     name="dp" ngbDatepicker #d="ngbDatepicker" (blur)="d.close()" 
[(ngModel)]="model"
     (select)="onDateSelected()">

This will work and onDateSelected() is called whenever you select a date in datepicker

Guess select output method is what you are looking for.

Select: An event fired when user selects a date using keyboard or mouse. The payload of the event is currently selected NgbDateStruct.

Refer the output section

Using dateSelect worked for me:

<input class="form-control"
     name="dp" ngbDatepicker #d="ngbDatepicker" (blur)="d.close(); ()onDateSelected()"
     [(ngModel)]="model">
