HTML DOM DFN object
The HTML DOM DFN object is associated with the HTML <dfn> element. The text inside the <dfn> element is the one being defined in the surrounding context. The DFN object represents the <dfn> element.
Syntax
Following is the syntax for −
Creating a DFN object −
var p = document.createElement("DFN");
Example
Let us look at an example for the HTML DOM DFN object −
<!DOCTYPE html>
<html>
<body>
<h2>DFN object example</h2>
<p>Click the below button to create a dfn element with some text inside it.</p>
<button onclick="dfnCreate()">CREATE</button> <br><br>
<script>
function dfnCreate() {
var x = document.createElement("DFN");
var t = document.createTextNode("The defination element");
x.appendChild(t);
document.body.appendChild(x);
}
</script>
</body>
</html>
Output
This will produce the following output −
On clicking the CREATE button −
We have first created a button CREATE that will execute the dfnCreate() function when clicked by the user −
<button onclick="dfnCreate()">CREATE</button>
The dfnCreate() method creates a <dfn> element using the createElement() method of the document object. It then creates a text node using the createTextNode() method. The text node is then appended as a child to the <dfn> element. Finally the <dfn> element along with the text node are appended as the child of the document body using the appendChild() method −
function dfnCreate() {
var x = document.createElement("DFN");
var t = document.createTextNode("The definition element");
x.appendChild(t);
document.body.appendChild(x);
}
