appendChild method

The appendChild method allows you to insert some other element at the end. Most commonly it used after creating an element with createElement.

Syntax

parent.appendChild(element);

Example

Let's create a paragraph, set its text and place it on a page at the end of the #parent block:

<div id="parent">
	<p>1</p>
	<p>2</p>
	<p>3</p>
</div>

let parent = document.querySelector('#parent');

let p = document.createElement('p');
p.textContent = '!';

parent.appendChild(p);

The code execution result:

<div id="parent">
	<p>1</p>
	<p>2</p>
	<p>3</p>
	<p>!</p>
</div>

Example

ul is given. Let's place 9 li tags in it, while setting serial numbers as their text:

<ul id="parent"></ul>

let parent = document.querySelector('#parent');

for (let i = 1; i <= 9; i++) {
	let li = document.createElement('li');
	li.textContent = i;
	parent.appendChild(li);
}

The code execution result:

<ul id="parent">
	<li>1</li>
	<li>2</li>
	<li>3</li>
	<li>4</li>
	<li>5</li>
	<li>6</li>
	<li>7</li>
	<li>8</li>
	<li>9</li>
</ul>

Example

Let's populate a table with tr's and td's:

<table id="table"></table>

let parent = document.querySelector('#parent');

for (let i = 1; i <= 3; i++) {
	let tr = document.createElement('tr'); // we create a tr
	
	// We populate tr with td's:
	for (let j = 1; j <= 3; j++) {
		let td = document.createElement('td'); // we create a td
		td.textContent = j; // write a text in it
		
		tr.appendChild(td); // add the created td to the end of the tr
	}
	
	table.appendChild(tr); // add the created tr to the end of the table
}

The code execution result:

<table id="table">
	<tr>
		<td>1</td>
		<td>2</td>
		<td>3</td>
	</tr>
	<tr>
		<td>1</td>
		<td>2</td>
		<td>3</td>
	</tr>
	<tr>
		<td>1</td>
		<td>2</td>
		<td>3</td>
	</tr>
</table>
