让页面动起来的WOW.js

## 简介有的页面在向下滚动的时候，有些元素会产生细小的动画效果。虽然动画比较小，但却能吸引你的注意。比如刚刚发布的 iPhone 6 的页面（查看）。如果你希望你的页面也更加有趣，那么你可以试试 WOW.js。
WOW.js 依赖 [animate.css](http://www.dowebok.com/98.html "animate.css – 齐全的CSS3动画库")，所以它支持 animate.css 多达 60 多种的动画效果，能满足您的各种需求。## 浏览器兼容| ![IE](http://upload-images.jianshu.io/upload_images/7001495-d1498e252dc65170.png?imageMogr2/auto-orient/strip%7CimageView2/2/w/1240 "IE")

IE6、IE7 等老旧浏览器不支持 CSS3 动画，所以没有效果；而 wow.js 也使用了 querySelectorAll 方法，IE 低版本会报错。为了达到更好的兼容，最好加一个浏览器及版本判断。## 使用方法### 1、引入文件<pre class="brush:xml" style="margin: 0px; padding: 10px; max-height: 400px; border: 1px solid rgb(240, 240, 240); font-style: normal; font-variant: normal; font-weight: 400; font-stretch: normal; font-size: 13px; line-height: 24px; font-family: Consolas, &quot;Lucida Sans Typewriter&quot;, &quot;Lucida Console&quot;, Monaco, &quot;Bitstream Vera Sans Mono&quot;, monospace; background-color: rgb(248, 248, 248); overflow: auto; color: rgb(102, 102, 102); letter-spacing: normal; orphans: 2; text-align: start; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;"><link rel="stylesheet" href="css/animate.min.css"></pre>### 2、HTML<pre class="brush:xml" style="margin: 0px; padding: 10px; max-height: 400px; border: 1px solid rgb(240, 240, 240); font-style: normal; font-variant: normal; font-weight: 400; font-stretch: normal; font-size: 13px; line-height: 24px; font-family: Consolas, &quot;Lucida Sans Typewriter&quot;, &quot;Lucida Console&quot;, Monaco, &quot;Bitstream Vera Sans Mono&quot;, monospace; background-color: rgb(248, 248, 248); overflow: auto; color: rgb(102, 102, 102); letter-spacing: normal; orphans: 2; text-align: start; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;"><div class="wow slideInLeft"></div>
<div class="wow slideInRight"></div></pre>
可以加入 data-wow-duration（动画持续时间）和 data-wow-delay（动画延迟时间）属性，如：
<pre style="margin: 0px; padding: 10px; max-height: 400px; border: 1px solid rgb(240, 240, 240); font-style: normal; font-variant: normal; font-weight: 400; font-stretch: normal; font-size: 13px; line-height: 24px; font-family: Consolas, &quot;Lucida Sans Typewriter&quot;, &quot;Lucida Console&quot;, Monaco, &quot;Bitstream Vera Sans Mono&quot;, monospace; background-color: rgb(248, 248, 248); overflow: auto; color: rgb(102, 102, 102); letter-spacing: normal; orphans: 2; text-align: start; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;"><div class="wow slideInLeft" data-wow-duration="2s" data-wow-delay="5s"></div>
<div class="wow slideInRight" data-wow-offset="10"  data-wow-iteration="10"></div></pre>### 3、JavaScript<pre class="brush:js" style="margin: 0px; padding: 10px; max-height: 400px; border: 1px solid rgb(240, 240, 240); font-style: normal; font-variant: normal; font-weight: 400; font-stretch: normal; font-size: 13px; line-height: 24px; font-family: Consolas, &quot;Lucida Sans Typewriter&quot;, &quot;Lucida Console&quot;, Monaco, &quot;Bitstream Vera Sans Mono&quot;, monospace; background-color: rgb(248, 248, 248); overflow: auto; color: rgb(102, 102, 102); letter-spacing: normal; orphans: 2; text-align: start; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;">new WOW().init();</pre>
如果需要自定义配置，可如下使用：
<pre class="brush:js" style="margin: 0px; padding: 10px; max-height: 400px; border: 1px solid rgb(240, 240, 240); font-style: normal; font-variant: normal; font-weight: 400; font-stretch: normal; font-size: 13px; line-height: 24px; font-family: Consolas, &quot;Lucida Sans Typewriter&quot;, &quot;Lucida Console&quot;, Monaco, &quot;Bitstream Vera Sans Mono&quot;, monospace; background-color: rgb(248, 248, 248); overflow: auto; color: rgb(102, 102, 102); letter-spacing: normal; orphans: 2; text-align: start; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;">var wow = new WOW({
    boxClass: 'wow',
    animateClass: 'animated',
    offset: 0,
    mobile: true,
    live: true});
wow.init();</pre>## 配置| 属性/方法 | 类型 | 默认值 | 说明 |
| --- | --- | --- | --- |
| boxClass | 字符串 | ‘wow’ | 需要执行动画的元素的 class |
| animateClass | 字符串 | ‘animated’ | animation.css 动画的 class |
| offset | 整数 | 0 | 距离可视区域多少开始执行动画 |
| mobile | 布尔值 | true | 是否在移动设备上执行动画 |
| live | 布尔值 | true | 异步加载的内容是否有效 |
