Example

Let us look at an example for the Input Range object −

 Live Demo

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

Output

This will produce the following output −

On clicking the CREATE button −

In the above example −

We have created a button CREATE that will execute the rangeCreate() method when clicked by the user −

<button onclick="rangeCreate()">CREATE</button>

The rangeCreate() method uses the createElement() method of the document object to create the <input> element by passing “INPUT” as a parameter. The newly created input element is assigned to variable R and using the setAttribute() method we create a type attribute with value range.

Remember, setAttribute() creates the attribute and then assigns value if the attribute doesn’t exist previously. Finally using the appendChild() method on document body we append the input element with type range as the child of the body −

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