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

Question

I am stuck on a very beginner problem in JS, what I'm trying to do is add line-breaks in between text which the script adds dynamically after generating a random string, but I could not find a source that would match my case

The code that picks a random string

var textArray = [
    'Gateway to wild imaginations!',
    'Activating the send portal :D',
    'Empowering nothing ;P'
];
var randomNumber = Math.floor(Math.random()*textArray.length);
var rndStr = textArray[randomNumber];

const h_1_elem = document.getElementById('main-h1');
h_1_elem.innerText = rndStr;

I would consider myself a beginner in programming so take this question with a pinch of salt

Answer 1

Don't use .innerText and instead use .innerHTML along with the HTML line break element of <br> :

 var textArray = [ 'Gateway to wild imaginations!', 'Activating the send portal :D', 'Empowering nothing ;P' ]; var rndStr = textArray[Math.floor(Math.random()*textArray.length)]; const h_1_elem = document.getElementById('main-h1'); h_1_elem.innerHTML = rndStr + "<br>"; rndStr = textArray[Math.floor(Math.random()*textArray.length)]; h_1_elem.innerHTML += rndStr + "<br>";

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

Answer 2

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>

If you run the code multiple times, you will get different messages. Just keep adding more :)

Oh, you want a break line after each word. Didn't understand the question that way. So, for that you should use something like this:

 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()].replaceAll(" ","\n"); function randomNumber() { let number = Math.floor(Math.random()*textArray.length); return number; }

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

I just used

replaceAll(" ", "\n")

In order to replace every space by a break line. Hope this is what you want.
