<div id="text">
</div>
</body>
<script>
let divTyping = document.getElementById('text')
let i = 0,
timer = 0,
str = 'hello worldn你好世界'
function typing () {
if (i <= str.length) {
let char = str.slice(0, i );
divTyping.innerHTML = '<span class="word">' str.slice(0, i ) '</span>' '<span class="cursor">|</span>';
timer = setTimeout('typing()', 200)
}
}
function disappear() {
let cursor = document.querySelector('.cursor');
cursor.innerHTML = '';
setTimeout(appear,200);
}
function appear() {
let cursor = document.querySelector('.cursor');
cursor.innerHTML = '|';
setTimeout(disappear,200);
}
typing();
disappear();
