### 一、什么是插件 ###

移动端要求的是快速开发，所以我们经常会借助于一些插件来帮我们完成操作，那么什么是插件呢？  
简单来说 js 插件就是一个 js 文件，它遵循一定规范编写，方便程序展示效果，拥有特定功能且方便调用，如轮播图和瀑布流插件。  
`它一般是为了解决某个问题而专门存在的，功能单一且非常小！`

### 二、fastclick 插件 ###

移动端 click 事件会有 300ms 的延迟，原因是移动端屏幕双击会缩放页面。fastclick 插件用于解决 300ms 延迟问题。

#### 1.使用步骤 ####

**① 浏览器打开上面的官网，找到 lib 目录并点击**

![在这里插入图片描述][ebdebe98afce40c7b79597b13a274654.png_pic_center]  
**② 找到 fastclick.js 点击**

![在这里插入图片描述][2e72f2c3a47846eab9f5a8254a3caf20.png_pic_center]  
**③ 打开后复制全部代码**

这些代码我已经复制好了，在下面的插件源码里面！

**④ 项目中新建一个 js 文件把以上代码粘贴进去，并在 html 中引入**

**⑤ 返回 GitHub 主页往下翻找到 Usage 下的这段代码复制上，粘贴到我们的 index.js 文件内**

### 三、Swiper 插件 ###

Swiper 是帮助我们写轮播图的一个插件！  
中文官网网址：`http://www.swiper.com.cn/`

#### 1.使用步骤 ####

**① 获取 Swiper，下载**  
![在这里插入图片描述][31d108f691c94d5d94c27832b4bedaad.png]

**② CSS 文件和 JS 文件在 dist 文件夹下，直接拿到我们的项目中去**  
打开之后，swiper.css 和 swiper.min.css 文件任选一个，它们的区别就是后者文件更小，所以我们选择 swiper.min.css。  
JS 文件同理，把它们拿到项目文件夹下。

**③ 在 HTML 页面中引入 CSS 文件和 JS 文件**  
注意我们的 index.js 是依赖于现在这个 js 文件的，所以把 index.js 放到下面。

**④ 打开 demos 文件夹，选择想要的模型右键查看源码**  
找到 body 部分选中并复制，直接将标签代码粘贴到我们轮播图模块的位置，注意不要更改类名。  
![在这里插入图片描述][d7afc714648f4311a975b87e7d6b65de.png_pic_center]  
继续回到刚才源码页面，找到 CSS 里面的 swiper 相关类，选中并复制，直接粘贴到页面 CSS 文件 index.css 里面。  
![在这里插入图片描述][80c7a2ac39584aadbce7229196621a89.png_pic_center]  
同样，JS代码也需复制，然后粘贴到 index.js 文件里面，注意先添加 window 加载事件。  
![在这里插入图片描述][fa90ba4c59e84cebabe8a48e4dd0772b.png_pic_center]  
`demos 文件夹下有许多不同编号的网页文件，自动切换效果的编号是280！`

#### 2.修改参数 ####

① 想要修改 index.js 里面的参数值，依然在中文网站首页找到 API 文档，这里面会告诉我们各个模块及参数都是什么样的功能，哪里不会点哪里，知道了含义，就可以自己更改参数值了；  
② 想要修改 index.css 里面的参数值，最简单的方法就是自己专门再写一个样式把原来那个覆盖掉，想要覆盖掉之前的样式，就必须提高权重，属性值后面加上 !important 即可。

### 四、zy.media.js 插件 ###

zy.media.js 是移动端的一个视频插件！  
H5 给我们提供了 video 标签，但是浏览器的支持情况不同，不同的格式的视频文件，我们可以通过  
source 解决，但是外观样式，还有暂停、播放、全屏等功能我们只能自己写代码解决，这个时候我们可以使用插件的方式来实现。
