Here is my setup with a mat-radio-group and a button:
<form action="">
<mat-radio-group aria-label="Select an option">
<mat-radio-button value="1">Option 1</mat-radio-button>
<mat-radio-button value="2">Option 2</mat-radio-button>
</mat-radio-group>
<button type="submit">Submit</button>
</form>
My goal is to make the button inactive unless a selection is made in the mat-radio group.
Here is a useful tip:
<md-radio-group [(ngModel)]="selectedOption">
<md-radio-button *ngFor="let item of optionsArray" [value]="item" (change)="handleRadioChange($event)">
{{item}}
</md-radio-button>
</md-radio-group>
In your .ts file:
handleRadioChange(event: MdRadioChange) {
this.enableSubmitButton = event.value; //This will result in a boolean value.
}
Once the radio button value changes, you can apply these classes to the button based on your requirements.
[class.fade-out]="!enableSubmitButton" [disabled]="!enableSubmitButton"
