HTML | DOM Superscript Object
  • Last Updated : 22 Jan, 2019

The superscript object in HTML DOM is used to represent the HTML <sup> element. The superscript element can be accessed by using getElementById().

Syntax:

document.getElementById("id") 

Where id is assigned to the <sup> tag.

Example :




<!DOCTYPE html> 
<html
    <head>
        <title>
            HTML DOM superscript Object
        </title>
    </head>
      
    <body style = "text-align:center"
      
        <h1 style = "color:green;"
            GeeksForGeeks 
        </h1>
          
        <h2>DOM superscript Object</h2
  
        <p>A<sup id="sup_scr">computer science</sup
        portal for geeks.</p>
          
        <button onclick="Geeks()">Click Here</button>
          
        <!-- script to set style in superscript object -->
        <script>
            function Geeks() {
                var txt = document.getElementById("sup_scr");
                txt.style.color = "green";
            }
        </script>
</body
</html>                    

Output:
Before click on the button:
sup
After click on the button:
sup

Example 2: Superscript Object can be created by using the document.createElement method.




<!DOCTYPE html> 
<html
    <head>
        <title>
            HTML DOM superscript Object
        </title>
    </head>
      
    <body style = "text-align:center"
      
        <h1 style = "color:green;"
            GeeksForGeeks 
        </h1
          
        <h2>DOM superscript Object</h2
  
        <button onclick = "Geeks()">
            Click Here!
        </button>
          
        <br><br>
          
        <div>A <span id = "p"></span> portal for geeks.</div>
          
        <script>
        function Geeks() {
            var txt = document.createElement("SUP");
            var t = document.createTextNode("computer science");
            txt.appendChild(t);
            document.getElementById("p").appendChild(txt);
        }
        </script>
</body
</html>
