How to force a line break on a Javascript concatenated string?

Question

I\'m sending variables to a text box as a concatenated string so I can include multiple variables in on getElementById call.

I need to specify a line break

Answer 1

document.getElementById("address_box").value = 
(title + "\n" + address + "\n" + address2 + "\n" + address3 + "\n" + address4);

Answer 2

You need to use \n inside quotes.

document.getElementById("address_box").value = (title + "\n" + address + "\n" + address2 + "\n" + address3 + "\n" + address4)

\n is called a EOL or line-break, \n is a common EOL marker and is commonly refereed to as LF or line-feed, it is a special ASCII character

Answer 3

You can't have multiple lines in a text box, you need a textarea. Then it works with \n between the values.

Answer 4

Using Backtick

Backticks are commonly used for multi-line strings or when you want to interpolate an expression within your string

let title = 'John';
let address = 'address';
let address2 = 'address2222';
let address3 = 'address33333';
let address4 = 'address44444';
document.getElementById("address_box").innerText = `${title} 
${address}
${address2}
${address3} 
${address4}`;

<div id="address_box">
</div>
