如何将日期选择器中的值绑定到angular2模型？

Question

I develop an app with angular2 and have to use a datepicker for firefox ( other browsers have in inbrowser datepicker ). The problem is by using a datepicker I loose the two way binding of my model. It doesn't matter if I use pikaday , jquery ui or other javascript datepickers. The behaviour is the same.

<input 
    type="date" 
    name="datum" 
    class="datepicker" 
    [(ngModel)]="datum" 
/>

Other way, same result

<input 
    type="date" 
    name="datum" 
    class="datepicker" 
    [value]="datum" 
    (input)="datum = $event.target.value" 
/>

jQuery UI datepicker fallback for firefox

(function() {
    var elem = document.createElement('input');
    elem.setAttribute('type', 'date');

    if ( elem.type === 'text' ) {
        $('.datepicker').datepicker(); 
    }
})();

If I pick a date it only appears in the input field, but doesn't exists as value in the model (btw, I tried a plunker but it failed because of the 'banana in a box' syntax [I can't bring jQuery to work in it]) .

Checkout this plunker to see the problem live (in firefox).

I know, this is a very specific problem, but maybe someone had it before and found a solution. And if this one can post it here this would make me very happy.

Answer 1

This works for me...ngModel is binding properly. you have not imported formsModule in your module.

Answer 2

you can add change event.

<input 
    type="date" 
    name="datum" 
    class="datepicker" 
    [ngModel]="datum" 
    (ngModelChange)="onChange($event)" 
/>


onChange(event : any){
  // add your code here
}
