Application scenario

It's not very useful. I just saw that there was a similar effect on the Internet. I wrote 40 or 50 lines of code that I couldn't understand, so I tried to realize it simply.

Html

Css h3 {width: 800px; line-height: 40px; border-bottom: 1px solid; margin: 200px auto; font-size: 24px;} .animate {display: inline-block; padding: 05px; vertical-align: 3px; font-size: 20px; font-weight: normal;} .animate.on {animation: fade 1.5s infinite forwards;} @ keyframes fade {from {opacity: 0;} to {opacity: 1 }}

Js

Let textBox = $('# text-box'); let index = 0 index str = 'Welcome to my websitekeeper; let len = str.length; function input () {textBox.html (str.substr (0, index) +' |'); setTimeout (function () {index++; if (index = len + 1) {$('.animate'). AddClass ('on'); return;} input () }, Math.random () * 600) console.log (index);} input (); Thank you for reading! This is the end of this article on "how to achieve typewriter effect with pure js".
