Creating a button object −
var x = document.createElement("BUTTON");Example
Let us see an example of the HTML DOM button object −
<!DOCTYPE html>
<html>
<body>
<p>Click on the below button to create a BUTTON element</p>
<button onclick="buttonCreate()">CREATE</button>
<br><br>
<script>
function buttonCreate() {
var x = document.createElement("BUTTON");
var t = document.createTextNode("NEW BUTTON");
x.appendChild(t);
document.body.appendChild(x);
}
</script>
</body>
</html>Output
This will produce the following output −
On clicking CREATE −
In the above example −
We have first created a button element CREATE. This button will execute the buttonCreate() function on click.
<button onclick="buttonCreate()">CREATE</button>
The buttonCreate() method uses the createElement() method of the document object to create a button element and assigned it to the variable x. A text node is created using the create element and assigned to variable t. The text node t is then appended to the button using the appendchild method. The button along with its child text node is then appended as a child to the document body using the document.body.appendChild() method.
function buttonCreate() {
var x = document.createElement("BUTTON");
var t = document.createTextNode("NEW BUTTON");
x.appendChild(t);
document.body.appendChild(x);
}
