Live Demonstration

<!DOCTYPE html>
<html>
<head>
<script>
   function createRadio() {
      var R = document.createElement("INPUT");
      R.setAttribute("type", "Radio");
      document.body.appendChild(R);
   }
</script>
</head>
<body>
<h1 id="Input-radio-object">Input radio object</h1>
<p>Create an input field with type radio by clicking the below button</p>
<button type=&rdquo;button&rdquo; onclick="createRadio()">CREATE</button>
<br><br>
Mango:
</body>
</html>

Output

This will produce The following output −

HTML DOM Input Radio 对象

Click the CREATE button −

HTML DOM Input Radio 对象

In the above example −

we A button named CREATE is created, and when the user clicks, the createRadio() method will be executed −

<button type=&rdquo;button&rdquo; onclick="createRadio()">CREATE</button>

The createRadio() method uses the createElement() method of the document object to create it by passing "INPUT" as a parameter element. The newly created input element is assigned to the variable R and using the setAttribute() method we create a type attribute with a value radio.

Remember, setAttribute() creates an attribute and assigns a value if the attribute does not previously exist. Finally, using the appendChild() method on the document body, we append an input element of type radio as a child element of the body -

function createPASS() {
   var R = document.createElement("INPUT");
   R.setAttribute("type", "Radio");
   document.body.appendChild(R);
}
