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

Question

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...

Solution 1

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

Solution 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

Solution 3

Here is the solution:

<input 
class="form-control"    
name="startDate" 
[(ngModel)]="startDate"
(dateSelect)="doSomething()"
(blur)="doSomething()"
ngbDatepicker 
#startDate="ngbDatepicker"
>

Here (dateSelect) handles choosing from the calendar picker and (blur) handles manually input when the input loses focus.

Solution 4

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.

(select) only applies to NgbDatepicker Component. I'm using the NgbInputDatepicker Directive here, with which (select) does not work unfortunately.

[Karthick Manoharan]

From the code you shared i can only see NgbDatepicker being used. Should you update your code?

[Florian Gössele]

That's because the selector of the NgbInputDatepicker Directive is also 'ngbDatepicker': ng-bootstrap.github.io/#/components/datepicker/examples (second demo) Or did I mess something up?

This only fires for me when I select a date using the calendar. NOT when typing in a date into the input field manually!

The event only fires when you select a date using the calendar. NOT when typing in a date manually.

@emirhosseini I know your comment is quite old, but now select is depricated and dateSelect still does not seem to fire on typing
