HTML DOM close() Method

Last Updated : 10 Aug, 2026

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 
<!--Driver Code Starts-->
<!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>
<!--Driver Code Ends-->

    <button onclick="geeks()">Submit</button>
    <script>
        function geeks() {
            document.open();
            document.write("<h1>PRACTICE</h1>");
            document.close();
        }
    </script>

<!--Driver Code Starts-->
</body>
  
</html>
<!--Driver Code Ends-->

Example 2: This example uses a window.close method to show the output in the new window. 

html 
<!--Driver Code Starts-->
<!DOCTYPE html>
<html>
  
<head>
    <style>
        h1,
        h2 {
            color: green;
        }
    </style>
</head>

<body>
    <h1>GeeksForGeeks</h1>
    <h2>DOM close() Method</h2>
<!--Driver Code Ends-->

    <button onclick="geeks()">Submit</button>
    <script>
        function geeks() {
            let gfg = window.open();
            gfg.document.open();
            gfg.document.write("<h1>PRACTICE</h1>");
            gfg.document.close();
        }
    </script>

<!--Driver Code Starts-->
</body>
  
</html>
<!--Driver Code Ends-->
  • Closes a script opened document stream : After document.open() and one or more document.write() calls, document.close() inserts an explicit end-of-file marker so the browser finishes parsing and renders the newly written content.
  • Has no effect (and is silent) if no open stream exists : Calling it on a normal page that was never opened with document.open() does nothing and raises no error; it only acts when a script-created parser is active.
