How to Break Line in JavaScript

How to break line in JavaScript?

Add %0D%0A to any place you want to encode a line break on the URL.

• %0D is a carriage return character
• %0A is a line break character

This is the new line sequence on windows machines, though not the same on linux and macs, should work in both.

If you want a linebreak in actual javascript, use the \n escape sequence.

Break line when string reaches X characters

If you want to break a string to certain length without cutting off any word, following code can help you:

const name = "YOUR_STRING";
const maxLen = 35; // you can play with this number to get desired result.

let result = name.substr(0, maxLen);
result = result.substr(0, Math.min(result.length, result.lastIndexOf(" ")));

How to break lines in javascript using .join

You can use a for loop with Array#slice.

const arr = ["a", "b", "c", "d", "e", "f", "g", "h", "i"];
const parts = [];
for(let i = 0; i < arr.length; i += 3){
  parts.push(arr.slice(i, i + 3).join(' '));
}
console.log(parts.join('\n'));

Line-breaks in between of text using JS ,(Dynamically)

You could use \n to insert a new line since you are using

h_1_elem.innerText = rndStr + "\n";

Also I created a function called randomNumber in order to call it more than one time.

var textArray = [
    'Gateway to wild imaginations!',
    'Activating the send portal :D',
    'Empowering nothing ;P'
];

const h_1_elem = document.getElementById('main-h1');
h_1_elem.innerText = textArray[randomNumber()] + "\n";
h_1_elem.innerText += textArray[randomNumber()] + "\n";

function randomNumber() {
  let number = Math.floor(Math.random()*textArray.length);
  return number;
}

<div id="main-h1"></div>

Break the line in a concatenated string based on a matching criteria and add line breaks

Using "br"

You can simply append the text using innerHTML like:

var content = "Test 1<br>Test 2<br>Test 3"
document.getElementById("result").innerHTML = content

<div id="result"></div>

How can I insert a line break into a Text component in React Native?

</Text>

How can I break line after specific scheme in text

As their documentation says here, you can pass options such as newline_char in chess.pgn() to decide what to add before every new line. You can pass \n which adds a new line in the <textarea> to show moves in a new line.

var updateEveryMove = function(){
  document.getElementById('pgnview').innerHTML = chess.pgn({newline_char: '\n'});
};
