使用typed.js来给你的网页添加打字效果吧

typed.js官网看这JavaScript Animated Typing with Typed.js | by Matt Boldt

typed.js

先看看效果:

右侧公告栏也是同样的方法

使用指北：

先在head或body里引入js

1	<script src="https://unpkg.com/[email protected]/dist/typed.umd.js"></script>

然后再创建一个自己的js文件，输入以下代码

1
2
3

var typed = new Typed('#hello-world', {
  strings: ['Hello World!']
});

在引入typed.js的cdn后面引入你的js文件

再在html里输入

1	<span id="hello-world"></span>

你就可以看到你的打字效果了

这里必须要span，如果是div的话光标会显示不正常，跑文字下一行去

当然这只是最基本的用法，你还可以在js里添加一些自定义的

如将strings替换为

strings: [
  '你猜这些是啥！',
  '你该干些啥！',
  '用你自己的!',
  '我去！',
],

并添加循环：

1 2	loop: true, loopCount: Infinity,

同时你可以在string中的文字里加上 ^3000 来让打字效果在此延迟3000毫秒再继续

如

strings: [
  '你猜这些^3000是啥！',
  '你该^5000干些啥！',
  '用你^2000自己的!',
  '我去^3000！',
],

它就会无限循环打字这几行文字

还可以设置打字速度，回溯速度

1 2	typeSpeed: 100, backSpeed: 50,

typed.js自带很多可自定义的

在GitHub - mattboldt/typed.js: A JavaScript Typing Animation Library
