referraluserid推广ID号跟踪JS处理A标签

 网站推广ID号跟踪

xxx.html?referraluserid=123

referraluserid.js 　　JS源文件 

referraluserid的参数会自动绑定页面A标签

有时是Post 表单跳转时不传数会丢失，这时可以根据后台或其它方式重新打印到前台页面，让Js重新获取到

<script type="text/javascript">

　　var referraluserid = '<%=BackReferraluserid%>';// BackReferraluserid 为后台值绑定到Js变量

</script>

紧接着引用JS文件

<script type="text/javascript" src="/Scripts/referraluserid.js"></script>
