JavaScript: appendChild: Create a child to node

By using ‘appendChild’ method, you can add a child to parent node.

Syntax

parentNode.appendChild(childNode);

process.js

function addData(){
 var para = document.createElement("p");
 var textNode = document.createTextNode("Good Morning");
 para.appendChild(textNode);
 
 var div = document.getElementById("data1");
 div.appendChild(para);
}

changeDom.html

<!DOCTYPE html>

<html>

<head>
    <title>Change DOM</title>
    <script src="process.js"></script>
</head>

<body>

    <div id="data1">
    </div>

    <input type="button" value="click me" onclick="addData();" />

    </div>
</body>

</html>

Open changeDom.html in browser, it shows the button ‘cilck me’. For every click of the button, it adds new paragraph with text "Good Morning" to the browser window.
