HTML DOM close() Method

The DOM close() method is used to close the output stream. It is used to indicate the finish of writing on a window. The close() method does not require any parameter.

Syntax:

document.close()

Example 1: In this example, we will use DOM close() method.

HTML

<!DOCTYPE html>
<html>
   
<head>
    <title>DOM close Method</title>
    <style>
        h1,
        h2 {
            color: green;
        }
    </style>
</head>
 
<body>
    <h1>GeeksForGeeks</h1>
    <h2>DOM close() Method</h2>
    <button onclick="geeks()">Submit</button>
    <script>
        // This function is called on submit, it opens
        // a stream, write "PRACTICE" and then closes
        // the stream.
        function geeks() {
            document.open();
            document.write("<h1>PRACTICE</h1>");
            document.close();
        }
    </script>
</body>
   
</html>
