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
<!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>
<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>Output:

margin-left: 45%;
margin-top: 30px;

<h2> DOM Input Button Object </h2>
<h3 style="color:green;">

<button onclick="myGeeks()">Submit</button>
<script>
function myGeeks() {
let g = document.createElement("INPUT");
g.setAttribute("type", "button");
g.setAttribute("value", "Click me");
g.setAttribute("id", "GFG");
document.body.appendChild(g);
}
