解决方案
为
I'm trying to format my date picker. I don't know the way. I tried inserting a moment.js library that I don't know how to use but copying it from the internet. Now my date picker returns an object moment and I don't know how to format this.
Component
this.form = this.fb.group({
deliveryDate: [this.deliveryDate], // i try to set here instead this.delieryDate null or moment() or everythink.....
address: [null, [Validators.required, Validators.minLength(5)]],
phone: [null, [Validators.minLength(9),Validators.maxLength(19)]],
city: [null, [Validators.required, Validators.minLength(5)]],
data: this.fb.array([this.createContact()])
});
Template
<mat-form-field>
<input matInput [matDatepicker]="picker" placeholder="Izaberite datum narudzbe"
formControlName="deliveryDate">
<mat-datepicker-toggle matSuffix [for]="picker"></mat-datepicker-toggle>
<mat-datepicker #picker></mat-datepicker>
</mat-form-field>
解决方案
The simplest way to set the initial date for an Angular Material Datepicker is to set an initial date value when constructing the form control.
Component
import {Component} from '@angular/core';
import {FormBuilder, FormControl, Validators} from '@angular/forms';
@Component({
selector: 'app',
templateUrl: './app.component.html',
styleUrls: ['./app.component.css']
})
export class AppComponent {
deliveryForm = this.fb.group({
deliveryDate: [new Date()],
address: [null, [Validators.required, Validators.minLength(5)]],
phone: [null, [Validators.minLength(9),Validators.maxLength(19)]],
city: [null, [Validators.required, Validators.minLength(5)]]
});
constructor(private fb: FormBuilder) { }
}
HTML Template
<form [formGroup]="deliveryForm">
<mat-form-field>
<input matInput [matDatepicker]="picker" placeholder="Izaberite datum narudzbe"
formControlName="deliveryDate">
<mat-datepicker-toggle matSuffix [for]="picker"></mat-datepicker-toggle>
<mat-datepicker #picker></mat-datepicker>
</mat-form-field>
<mat-form-field>
<input matInput formControlName="address" placeholder="Address"
autocomplete="address-line1">
</mat-form-field>
<mat-form-field>
<input matInput formControlName="phone" placeholder="Phone number"
autocomplete="tel-national">
</mat-form-field>
<mat-form-field>
<input matInput formControlName="city" placeholder="City" autocomplete="address-level2">
</mat-form-field>
</form>
