网站分析统计JS源码分享

之前公司做了一个分析云平台，用来跟踪收集海量的用户行为的相关数据，供运营人员实时监控网站访问量，统计PV，UV，独立IP，访问时段，访问时长，热点追踪等多类信息，我用JS写了一个小插件，只需要再页面加载这个js文件即可，供有需要的朋友参考，该插件分为两部分组成，一部分是分析的主JS，另一部分功能是用来提供热点地图绘制信息。

/**
 *  分析主JS，该JS部署时放在页面标签之前，所有引入的其他JS位置之后
 *  该JS文件会自动加载hot.js文件，进行行为追踪，无需配置。
 *  配置说明：
 *  如果追踪页面加载速度，需要在页面标签内靠前位置Javascript语句块中嵌入代码： var _speedMark = new Date(); 如不配置，该功能不可用，这种方式实现比较传统，为的是兼容更多的浏览器，如果只考虑高版本的浏览器，可以用很简单很直接的方式来解决。这里就不累赘讲述了。

/**************************参数说明********************************
 *
 *  bs      浏览器及版本，中间固定用“/”隔开： 如   Firefox/29
 *  fl    Flash版本：如 13.0 r0
 *  hp    是否设置为首页，y表是，否则为空
 *  jv    是否禁用脚本：0表否，1表是
 *  lg    浏览器语言：如 zh-cn
 *  ps      页面加载用时：如 271 单位为毫秒，如没配置该属性，ps没值，网页首次加载有值，其它情况下值为0
 *  pvi      用户标识：如 5699369775 第一次访问页面时产生，只要用户不清除客户端cookie，该值永远存在
 *  rurl  上一个页面地址
 *  scl   屏幕颜色深度：如 24-bit
 *  scr      屏幕分辨率: 如 1600x900
 *  sh      滚动条可滚动高度：如 3259
 *  si      本地一次会话标识： 如 s479879256
 *  tz      区时：如 8
 *  ui      登陆的用户ID，未登陆时没有该值：如 7155113994790596
 *  url      当前的URL
 *  x     鼠标点击事件时，相对body中轴线的x坐标， 中轴线左边为负，右边为正，此值只有开启热点追踪时才会产生，页面初始化时无值
 *  y     鼠标点击事件时的y坐标，此值只有开启热点追踪时才会产生，页面初始化时无值
