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

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

CodePudding user response：

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>

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 :)
