HTML | DOM Script Object

Last Updated : 04 Oct, 2019

The DOM Script Object is used to represent the HTML <script> element. The script element is accessed by getElementById(). Properties:

async: It is used to specify the script is executed asynchronously.
charset: It is used to specify the character encoding used in an external script file.
defer: It is used to specify that the script is executed when the page has finished parsing.
src: It is used to specify the URL of an external script file.
type: It is used to specify the media type of the script.

Syntax:

document.getElementById("ID");

Where “id” is the ID assigned to the “script” tag. Example-1:

html

<!DOCTYPE html>
<html>

<head>
    <style>
        body {
            text-align: center;
        }
        
        h1 {
            color: green;
        }
    </style>
</head>

<body>
    <h1>GeeksForGeeks</h1>
    <h2>DOM Script Object </h2>
  
    <!-- Assigning id to script. -->
    <script id="GFG">
        Hello GeeksForGeeks!
    </script>
    <br>
    <br>
  
    <button onclick="myGeeks()">Submit</button>

    <p id="sudo"></p>

    <script>
        function myGeeks() {
          
            //  Accessing script object
            var g = document.getElementById(
              "GFG").text;
            document.getElementById(
              "sudo").innerHTML = g;
