HTML DOM Input Button Object

Last Updated : 14 Jun, 2023

The DOM Input Type Button Object is used to represent the HTML <input> element with type=”button”. The Input Type Button element is accessed by getElementById().

Syntax:

document.getElementById("ID");

Where “id” is the ID assigned to the “input” tag.

Example 1: In this example, we will see the use of the DOM Input Button Object

HTML

<!DOCTYPE html>
<html>
<head>
    <style>
        h1 {
            color: green;
        }
    </style>
</head>
   
<body>
    <h1>GeeksForGeeks</h1>
    <h2> DOM Input Button Object </h2>
   
    <!-- Assigning button id -->
    <input type="button" id="GFG" onclick="myGeeks()" value="Submit">
    <p id="sudo"></p>
 
    <script>
        function myGeeks() {
           
            // accessing 'button' id.
            let g = document.getElementById("GFG").value;
            document.getElementById("sudo").innerHTML = 
              "Value od input type button is:" + g;
        }
    </script>
</body>
</html>
