效果如图：
实现：
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Title</title> </head> <body> <div id="text"> </div> </body> <script> let divTyping = document.getElementById('text') let i = 0, timer = 0, str = 'hello world\n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(); </script> </html>
