title: How to get the value of the selected radio button in angular
body: <p>What's the best way to get the value of the selected radio button in angular?<br>
  <a href="https://juristr.com/blog/2016/11/ng2-binding-radiobutton-lists/" rel="nofollow noreferrer">This link</a> shows the implementation with data binding.
  I just want to get the value in <code>onSelectionChange</code> method which is the <code>change</code> event handler.<br>
  Maybe I can code as the following:</p>
  
  <p><code>&lt;input type="radio" value="beauty" (change)="onSelectionChange($event)" checked&gt;</code></p>
  
  <pre><code>  private onSelectionChange(event) {
      alert(event.srcElement.value);
    }
  </code></pre>
  
  <p>Is it a good practice?</p>
