插件描述：typed.js是一个类型库，输入任意字符串，它将以打字方式显示出来。您可以设置打字速度，退格等参数。
typed.js安装
npm、yarn、bower
npm install typed.js
yarn add typed.js
bower install typed.js
CDN
<script src="https://cdn.jsdelivr.net/npm/typed.js@2.0.12"></script>
设置
这就是您开始所需的全部内容。
// 也可以包含在常规脚本标签中
import Typed from 'typed.js';
var options = {
strings: ['<i>First</i> sentence.', '& a second sentence.'],
typeSpeed: 40
};
var typed = new Typed('.element', options);
静态 HTML 的字符串 （SEO 友好）
与其使用字符串阵列插入字符串，不如在页面上放置 HTML div 并从中读取。这允许机器人和搜索引擎，以及具有 JavaScript 禁用的用户在页面上查看您的文本。
<script>
var typed = new Typed('#typed', {
stringsElement: '#typed-strings'
});
</script>
<div id="typed-strings">
<p>Typed.js is a <strong>JavaScript</strong> library.</p>
<p>It <em>types</em> out sentences.</p>
</div>
<span id="typed"></span>
类型暂停
您可以通过包含转义字符在字符串中间暂停给定的时间。
var typed = new Typed('.element', {
// Waits 1000ms after typing "First"
strings: ['First ^1000 sentence.', 'Second sentence.']
});
智能退格
在以下示例中，这只会退格“This is a”之后的单词
var typed = new Typed('.element', {
strings: ['This is a JavaScript library', 'This is an ES6 module'],
smartBackspace: true // Default value
});
批量打字
以下示例将模拟终端在键入命令并查看其结果时的行为。
var typed = new Typed('.element', {
strings: ['git push --force ^1000\n `pushed to origin with option force`']
});
CSS
CSS 动画建立在 JavaScript 的初始化之上。 但是，您可以随意自定义它们！ 这些类是：
/* Cursor */
.typed-cursor {
}
/* If fade out option is set */
.typed-fade-out {
}
