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().

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:

<!DOCTYPE html> 
<html>
