HTML DOM dl Object

Last Updated : 14 Jun, 2023

The DOM dl object is used to represent the HTML <dl> element. The dl element can be accessed using the 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() {
           let doc = document.getElementById("id").innerHTML;
            document.getElementById("p").innerHTML = doc;
        }
    </script>
</body>
</html>

Output:

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

            // Creating a dl element
            let doc = document.createElement("DL");
            doc.setAttribute("id", "dl");
            document.body.appendChild(doc);
 
            // Creating a DT element
            let doc1 = document.createElement("DT");
            let txt1 = document.createTextNode("Sorting");
            doc1.appendChild(txt1);
            doc1.setAttribute("id", "dt");
            document.getElementById("dl").appendChild(doc1);
 
            // Creating a dd element
            let doc2 = document.createElement("DD");
            let txt2 = document.createTextNode("Merge sort");
            doc2.appendChild(txt2);
            document.getElementById("dl").appendChild(doc2);
