HTML DOM Dialog Object

Last Updated : 13 Jun, 2023

The DOM Dialog Object is used to represent the HTML <dialog> element. The Dialog element is accessed by getElementById(). It is used in HTML5.

Syntax:

document.getElementById("ID");

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

Example 1: In this example, we will use DOM Dialog Object.

HTML

<!DOCTYPE html>
<html>
<head>
    <title>DOM dialog Object</title>
    <style>
        dialog {
            color: green;
            font-size: 30px;
            font-weight: bold;
            font-style: italic;
        }
        body {
            text-align: center;
        }
    </style>
</head>
<body>
    <h1>DOM Dialog Object</h1>
    <!-- Assigning id to dialog tag -->
    <dialog id="GFG">Welcome to GeeksforGeeks</dialog>
    <button onclick="myGeeks()" open>Submit</button>
    <script>
        function myGeeks() {
            // Accessing dialog tag
            let x = document.getElementById("GFG");
            x.open = true;
        }
    </script>
</body>
</html>

Output:

Example 2: Dialog Object can be created by using the document.createElement Method.
