HTML DOM Radio object
Radio Object
Radio objects represent radio buttons in HTML forms.
In HTML forms, one Radio object is created for every time it appears.
A turn button is one of a set of mutually exclusive option buttons. When a button is selected, the previously selected button becomes unchecked.
When a turn button is selected or not selected, the button triggers the onclick event handle.
You can access the Radio object by traversing the form's array of elements, or by using document.getElementById().
