append method

The append method allows you to insert another element at the end of an element. The method takes an element as a parameter, usually created with createElement, or a string. You can add several elements or strings at once by listing them separated by commas.

Syntax

parent.append(element or string);

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.append(p);

The code execution result:

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

Example

Let's put several paragraphs at once 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 p1 = document.createElement('p');
p1.textContent = 'a';

let p2 = document.createElement('p');
p2.textContent = 'b';

parent.append(p1, p2);

The code execution result:

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

Example

Let's use a string as a method parameter:

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

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

The code execution result:

<div id="parent">
	<p>1</p>
	<p>2</p>
	<p>3</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.append(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 table = document.querySelector('#table');

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.append(td); // add the created td to the end of the tr
	}
	
	table.append(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>
