HTML | DOM dl Object

  • Last Updated : 28 Jun, 2021

The DOM dl object is used to represent the HTML <dl> element. The dl element can be accessed using getElementById() method. The dl is used to create a description list in HTML.

Syntax: 

document.getElementById("id"); 

Where ‘id’ is the ID assigned to the dl tag.

Example-1: In the below program the dl element is accessed and the color of the text inside the description list is changed.  

html




<!DOCTYPE html>
<html>
<body>
        <h1 style = "color:green;" >
          GeeksForGeeks
        </h1>
        <h2>DOM dl Object</h2>
 
        <dl id="id">
          <dt>Sorting</dt>
          <dd>Merge sort</dd>
        </dl>
         
        <button onclick="Geeks()">Click Here!</button>
         
        <p id="p" style="color:green"></p>
 
         
        <script>
        function Geeks() {
          var doc = document.getElementById("id").innerHTML;
 
          document.getElementById("p").innerHTML = doc;
        }
        </script>
</body>
</html>
