HTML DOM dl object
The HTML DOM dl object is associated with the HTML <dl> element. The <dl> element is for creating the description list. Using the dl object we can dynamically create and acess the <dl> element using JavaScript.
Syntax
Following is the syntax for −
Creating a description list −
var p = document.createElement("DL");
Example
Let us look at an example for the dl object −
<!DOCTYPE html>
<html>
<body>
<h2>Div object example</h2>
<p>Create a div by clicking the below button</p>
<button onclick="createDiv()">CREATE</button>
<script>
function createDiv() {
var Desc = document.createElement("DL");
var DesT = document.createElement("DT");
var tn= document.createTextNode("Mango");
DesT.appendChild(tn);
var data = document.createElement("DD");
var tn1 = document.createTextNode("Mango is the king of fruits");
data.appendChild(tn1);
document.body.appendChild(Desc);
Desc.appendChild(DesT);
Desc.appendChild(data);
}
</script>
</body>
</html>
Output
This will produce the following output −
On clicking the CREATE button −
In the above example −
We have first created a button CREATE that will execute the createDiv() method on being clicked by the user −
<button onclick="createDiv()">CREATE</button>
The createDiv() method creates a <dl>, <dt> and <dd> element using the createElement() method of the document object and assings the elements to Desc, DesT and data variables respectively. We then create text node for the <dt> and <dd> element using the createTextNode() method and append them to their respective elements using the appendChild() method.
Finally, we append the <dt> element to <dl> and then <dd> element. The <dl> element is then appended along with the <dt> and <dd> element to the document body using the appendChild() method −
function createDiv() {
var Desc = document.createElement("DL");
var DesT = document.createElement("DT");
var tn= document.createTextNode("Mango");
DesT.appendChild(tn);
var data = document.createElement("DD");
var tn1 = document.createTextNode("Mango is the king of fruits");
data.appendChild(tn1);
document.body.appendChild(Desc);
Desc.appendChild(DesT);
Desc.appendChild(data);
}
