I am wondering of a way to validate required checkbox in the same style angular material handles validation for other controls - on form submission, the control appears red unless touched.
I think I can do this with ng-style
however, I can't think of a way to check if the form has been submitted
Here is a snippet of the HTML
<form [formGroup]="frmFinish" name="frmFinish">
<mat-checkbox required formControlName="check1">Discussed Confidentiality and Information Sharing with Service User</mat-checkbox>
<mat-checkbox required formControlName="check2">Discussed Disposal and Storage of Injecting Equipment and Substances</mat-checkbox>
<mat-checkbox required formControlName="check3">Discussed Overdose Risk and Prevention</mat-checkbox>
<mat-form-field>
<textarea formControlName="note" [(ngModel)]="stepFive.note" matInput placeholder="Any Additional Notes" matTextareaAutosize matAutosizeMinRows="2" matAutosizeMaxRows="5"></textarea>
<mat-hint align="end">This will be added to the profiles note's</mat-hint>
</mat-form-field>
<mat-card-actions>
<button mat-raised-button type="button" class="nav-btn pull-right" (click)="fillForm()" style="background: red">Fill Form</button>
<button mat-raised-button class="nav-btn pull-right" style="margin-left:5px;" (click)="createProfile()" type="submit">Finish</button>
<button mat-raised-button matStepperPrevious class="nav-btn pull-right">Previous</button>
</mat-card-actions>
</form>
And here is the typescript:
import { Component } from '@angular/core';
import { FormBuilder, FormGroup, Validators } from '@angular/forms';
import { CreateProfileComponent } from '../create-profile.component';
@Component({
selector: 'step-five-component',
templateUrl: './step-five.component.html',
styleUrls: ['../create-profile.component.css']
})
export class StepFiveComponent {
frmFinish: FormGroup;
stepFive = {
note: null
};
constructor(private formBuilder: FormBuilder) {
this.frmFinish = this.formBuilder.group({});
}
ngOnInit() {
this.frmFinish = this.formBuilder.group({
note: ['', Validators.required],
check1: ['', Validators.required],
check2: ['', Validators.required],
check3: ['', Validators.required],
});
}
createProfile(){
if(this.frmFinish.valid){
console.log('Creating profile..');
}else{
}
}
fillForm(){
this.stepFive.note = 'asdasd';
}
}
This was resolved in Angular version 2.3.0.
Simply use: Validators.requiredTrue
instead of Validators.required
.
(See GitHub issue #11459. See Angular docs requiredTrue)
