Issues with the md-radio-button not functioning properly in Angular 2

I'm in need of two radio buttons to choose between two options. Here's the code I'm using:

<md-radio-button [value]=true [(ngModel)]="carSelected" name="carOption">Car</md-radio-button>
<md-radio-button [value]=false [(ngModel)]="carSelected" name="busOption">Bus</md-radio-button>

Within my component, I've declared a boolean variable called carSelected:

public carSelected: boolean = true;

However, the radio buttons aren't updating with the value of carSelected. Additionally, when a radio button is selected, carSelected remains unchanged. What could be causing this issue?

angulartypescript

Answer №1

Here is a sample code snippet in HTML:

<md-radio-group [(ngModel)]="vehicleTypeSelected">
  <md-radio-button [value]=true name="vehicleOption">Car</md-radio-button>
  <md-radio-button [value]=false name="vehicleOption">Bus</md-radio-button>
</md-radio-group>

In your component file:

public vehicleTypeSelected: boolean = true;

Answer №2

First and foremost, radio buttons must have the same names in order to function as intended. Your code looks good otherwise.

Make sure to bind ngModel to the <md-radio-group> tag, not the <md-radio-button> tag.

I hope this information proves useful.

Answer №3

Give this a try. It's been effective for me. There's a method we can utilize to trigger changes. By using this method, you can pass the necessary value.

  <md-radio-group class="example-radio-group" [(ngModel)]="carSelected">
    <md-radio-button [value]=true (change)="getval('car')">Car</md-radio-button>
    <md-radio-button [value]=false (change)="getval('Bus')">Bus</md-radio-button>
  </md-radio-group>

In my TS File

getval(car){
  this.carSelected=true;
  console.log(car)
}

Check out the API reference here. Angular material 2 offers a range of possibilities.
