Angular 2 Date Input not binding to date value
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.
Angular 2 , 4 and 5 :
the simplest way : plunker
<input type="date" [ngModel] ="dt | date:'yyyy-MM-dd'" (ngModelChange)="dt = $event">
Instead of [(ngModel)] you can use:
// view
<input type="date" #myDate [value]="demoUser.date | date:'yyyy-MM-dd'" (input)="demoUser.date=parseDate($event.target.value)" />
// controller
parseDate(dateString: string): Date {
if (dateString) {
return new Date(dateString);
}
return null;
}
You can also choose not to use parseDate function. In this case the date will be saved as string format like "2016-10-06" instead of Date type (I haven't tried whether this has negative consequences when manipulating the data or saving to database for example).
In your component
let today: string;
ngOnInit() {
this.today = new Date().toISOString().split('T')[0];
}
and in your html file
<input name="date" [(ngModel)]="today" type="date" required>
