The HTML DOM appendChild() method is used to create and add a text node at the end of the list of child nodes. The appendChild() method can also be used to move an element from current position to a new position. Using appendChild() you can add new values to a list and can even add a new paragraph under another paragraph.
Syntax
Following is the syntax for appendChild() Method −
node.appendChild( node )
Here, the parameter node is the object that you want to append. It is a compulsory parameter value.
Example
Let us see an example of appendChild() Method −
<!DOCTYPE html>
<html>
<body>
<p>Click the button to create a paragraph and append it to the div</p>
<div id="SampleDIV">
A DIV element
</div>
<button onclick="AppendP()">Append</button>
<script>
var x=1;
function AppendP() {
var paragraph = document.createElement("P");
paragraph.innerHTML = "This is paragraph "+x;
document.getElementById("SampleDIV").appendChild(paragraph);
x++;
}
</script>
</body>
</html>Output
This will produce the following output −
After clicking append 3 times: −
In the above example −
We have created a div with id “SampleDIV”. The appended node will act as child of this div.
<div id="SampleDIV"> A DIV element </div>
We have then a button named “Append” which will execute the function AppendP()
<button onclick="AppendP()">Append</button>
The AppendP() function first creates a paragraph (p) element and assigns it to variable paragraph. Then some text is added to paragraph using innerHTML and a variable x is appended to text. This variable is incremented each time we click the ”Append” button. At last we append the newly created paragraph as a child node of the div element −
var x=1;
function AppendP() {
var paragraph = document.createElement("P");
paragraph.innerHTML = "This is paragraph "+x;
document.getElementById("SampleDIV").appendChild(paragraph);
x++;
}
