HTML DOM Heading object
The HTML DOM Heading object is associated with the HTML heading elements ranging from <h1> to <h6>. Using the heading object we can create and access heading element with the createElement() and getElementById() method respectively.
Syntax
Following is the syntax for −
Creating a Heading object −
var p = document.createElement("H1");
Example
Let us look at an example for the Heading object −
<!DOCTYPE html>
<html>
<body>
<h1>Heading object example</h1>
<p>Create a h1 element by clicking the below button</p>
<button onclick="createH1()">CREATE</button>
<script>
function createH1() {
var h = document.createElement("H1");
var txt = document.createTextNode("H1 element has been created");
h.appendChild(txt);
document.body.appendChild(h);
}
</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 headerCreate() method when clicked by the user −
<button onclick="createH1()">CREATE</button>
The CreateH1() method creates an <h1> heading element using the createElement() method on document object and assigns it to variable h. We then create a text node for it using the createTextNode() method of the document object. The text node is appended to the <h1> element using the appendChild() method. Finally the <h1> element along with the text node are appended as child of the document’s body using the appendChild() method −
function createH1() {
var h = document.createElement("H1");
var txt = document.createTextNode("H1 element has been created");
h.appendChild(txt);
document.body.appendChild(h);
}
