Angular 2 Date Input not binding to date value

Question

trying to get a form set up but for some reason, the Date input in my html is not binding to the object's date value, despite using [(ngModel)]

html:

<input type='date' #myDate [(ngModel)]='demoUser.date'/><br>

form component:

export class FormComponent {
    demoUser = new User(0, '', '', '', '', new Date(), '', 0, [], []);  
}

User class:

export class User {
    constructor (
        public id: number,
        public email: string,
        public password: string,
        public firstName: string,
        public lastName: string,
        public date: Date,
        public gender: string,
        public weight: number,
        public dietRestrictions: string[],
        public fitnessGoals: string[]
    ){

    }
}

A test output reveals the current "new" Date as the object's value, but the input doesn't update the User object's date value or reflect the value, suggesting neither of the two-way bindings are working. Help would be greatly appreciated.

Answer 1

As per HTML5, you can use input type="datetime-local" instead of input type="date".

It will allow the [(ngModel)] directive to read and write value from input control.

Note: If the date string contains 'Z' then to implement above solution, you need to trim the 'Z' character from date.

For more details, please go through this link on mozilla docs.

Answer 2

Angular 2 completely ignores type=date. If you change type to text you'll see that your input has two-way binding.

<input type='text' #myDate [(ngModel)]='demoUser.date'/><br>

Here is pretty bad advise with better one to follow:

My project originally used jQuery. So, I'm using jQuery datepicker for now, hoping that angular team will fix the original issue. Also it's a better replacement because it has cross-browser support. FYI, input=date doesn't work in Firefox.

Good advise: There are few pretty good Angular2 datepickers:

In .ts :

today: Date;

constructor() {  

    this.today =new Date();
}

.html:

<input type="date"  
       [ngModel]="today | date:'yyyy-MM-dd'"  
       (ngModelChange)="today = $event"    
       name="dt" 
       class="form-control form-control-rounded" #searchDate
