How to Create Typing Effect Using JavaScript (Source Code)

 

Welcome to the Codewithrandom blog. In this blog, We learn how to create a Typing Effect Using JavaScript. We use HTML, CSS, and JavaScript for this Typing Effect Project.

I hope you enjoy our blog so let’s start with a basic html structure for a Typing Effect.

HTML Code For Typing Effect

<div class="container">
<p>CODEWITHRANDOM is for <span class="typed-text"></span><span class="cursor">&nbsp;</span></p>
</div>

There is all the html code for the Typing Effect. Now, you can see output without Css and JavaScript. Then we write Css for styling typing effects and use javascript for Typing Effect Animation functionality.

}
@keyframes blink {

JavaScript Code For Typing Effect

const typedTextSpan = document.querySelector(".typed-text");
const cursorSpan = document.querySelector(".cursor");
const textArray = ["project", "fun", "free stuff", "tutorial"];
const typingDelay = 100;
const erasingDelay = 100;
const newTextDelay = 2000; // Delay between current and next text
let textArrayIndex = 0;
let charIndex = 0;
function type() {
if (charIndex < textArray[textArrayIndex].length) {
if(!cursorSpan.classList.contains("typing")) cursorSpan.classList.add("typing");
typedTextSpan.textContent += textArray[textArrayIndex].charAt(charIndex);
charIndex++;
setTimeout(type, typingDelay);
}
else {
cursorSpan.classList.remove("typing");
setTimeout(erase, newTextDelay);
}
}
function erase() {
if (charIndex > 0) {
if(!cursorSpan.classList.contains("typing")) cursorSpan.classList.add("typing");
typedTextSpan.textContent = textArray[textArrayIndex].substring(0, charIndex-1);
charIndex--;
setTimeout(erase, erasingDelay);
}
else {
cursorSpan.classList.remove("typing");
textArrayIndex++;
if(textArrayIndex>=textArray.length) textArrayIndex=0;
setTimeout(type, typingDelay + 1100);
}
}
document.addEventListener("DOMContentLoaded", function() { // On DOM Load initiate the effect
if(textArray.length) setTimeout(type, newTextDelay + 250);
});
