收集用户隐私的行径眼下已不再是什么新鲜的话题（与其说是收集，不如说是偷窥），就连G、MS也屡出风头，当然事出有因，企业通过无法八门的各种手段了解用户的行为，进而作为决策支持的依据；通常表现为跨领域的收集（浏览器、智能系统、OS etc.）、业务、产品数据的收集，当然收集的方式也不一而论。以下展示通过客户端脚本方式收集Web站点用户行为数据的实现方式，以此来判断页面加载过程、执行时间、用户停留时间、页面提交率、成功率、页面错误等（本示例实现较为简单，在特定复杂的业务数据收集时，可适当重构与改造）。

1、收集基础数据

基础数据涵盖

（1）业务类：业务流页面地址、用户停留时间、打开次数、

会话ID、客户端IP、业务流步骤等

（2）辅助类：浏览器、OS、COOKIE等

（3）示例

2、时间统计

通过在页面放置计时器，计算当前视图下用户的停留时间。

示例：

/*--------Timer Script-------------

*
* 页面计时器控件
* 1、Timer.BindControl = ‘inputTimer‘;
* 2、<input id="inputTimer" type="hidden" class="timer" />
* 不写Cookie、不显示定时器时,采用(EndTime - StratTime)即可
*/
var up, down;
var cmin1, csec1, clock;
var Timer = {
Debug: false,
BindControl: ‘inputTimer‘,
StartTime: ‘‘,
EndTime: ‘‘,
StartTimer: function() {
if (!$f(this.BindControl)) return;
if ($f(this.BindControl).value != "") return;
//$("#" + this.BindControl).val("");
cmin1 = 0;
csec1 = 0;
//每个页面单独记录,不需要采用Cookie,屏蔽
// var cookie = GetCookie("Timer");
// if (cookie) {
// cmin1 = parseInt(this.Minutes(cookie));
// csec1 = parseInt(this.Seconds(cookie));
// DeleteCookie("Timer");
// }
// else {
// cmin1 = csec1 = 0;
// }
this.Repeat();
},
SetValue: function() {
var html = $f(this.BindControl).value;
if (html != null && html.length > 0) SetCookie("Timer", html);
},
Minutes: function(data) {
for (var i = 0; i < data.length; i++) if (data.substring(i, i + 1) == ":") break;
return (data.substring(0, i));
},
Seconds: function(data) {
for (var i = 0; i < data.length; i++) if (data.substring(i, i + 1) == ":") break;
return (data.substring(i + 1, data.length));
},
Display: function(min, sec) {
var disp = "";
if (min <= 9) disp += "0" + min + ":";
else disp += min + ":";
if (sec <= 9) disp += "0" + sec;
else disp += sec;
return (disp);
},
Repeat: function() {
csec1++;
if (csec1 == 60) { csec1 = 0; cmin1++; }
$f(this.BindControl).value = this.Display(cmin1, csec1);
if (this.Debug) $f("inputDebug").value = this.Display(cmin1, csec1);
clock = window.setTimeout(function() { Timer.Repeat() }, 1000);
},
//重新开始计时
Reset: function() {
$f(this.BindControl).value = "";
window.clearTimeout(clock);
Timer.StartTimer();
},
AddTrigger: function() {
var list = document.getElementsByTagName("INPUT");
for (var i = 0; i < list.length; i++) {
if (list[i].type.toUpperCase() == ‘TEXT‘) {
if (list[i].addEventListener) {
list[i].addEventListener("keyup", function() { Timer.StartTimer(); }, false);
}
else {
list[i].attachEvent("onkeyup", function() { Timer.StartTimer(); });
}
}
}
}
};
if (document.all) {
window.attachEvent("onload", function() { Timer.AddTrigger() });
}
else {
window.addEventListener("load", function() { Timer.AddTrigger() }, false);
}
if (Timer.Debug) {
if (!document.getElementById("inputDebug")) {
document.write("<input type=‘text‘ id=‘inputDebug‘ />");
}
}
/* 兼容两种模式设定Cookie */
//$(window).unload(function() { Timer.SetValue(); });
//$("form").submit(function() { Timer.SetValue(); });

3、异步记录

将收集到的数据通过GET、POST异步的方式发送到目标服务器

示例：

/*--------Trace Script-------------*/

var Step =
{
/* step */
step1: "step1", //第一步打开,不含历史返回、成功返回
step2: "step2",
step3: "step3",
/* post */
step1submit: "step1submit", //第一步提交
step2submit: "step2submit",
step3submit: "step3submit",
step3resubmit: "step3resubmit", //第三步重新提交
/* success */
success:"success", //操作成功
succret: "succret", //成功返回
step1ret: "step1ret", //返回第一步
step2ret: "step2ret",
step3ret: "step3ret",
/* error */
error:"error", //操作失败
errstep1: "errstep1", //第一步出错错误页面记录
errstep2: "errstep2",
errstep3: "errstep3",
errstep1ret: "errstep1ret", //出错页返回到第一步
errstep2ret: "errstep2ret",
errstep3ret: "errstep3ret",
/* login */
loginb1: "loginb1", //银行卡登录返回
loginc1: "loginc1", //实物卡登录返回
loginbind: "loginbind", //一点充登录返回
step1login: "step1login", //第一步登录界面
/* other */
bind: "bind", //用户绑定一点充
mobile: "mobile", //修改手机号
password: "password", //修改密码
cancelbind: "cancelbind", //取消服务
Login: "Login", //用户登录日志
querydeposit: "querydeposit", //充值记录
querycardbalance: "querycardbalance", //实物卡余额
clickkf: "clickkf", //点击在线客服
closekf: "closekf", //关闭在线客服
clickaccount1: "clickaccount1", //点击新增常用账号
clickaccount2: "clickaccount2" //点击新增确定按钮
};
var Environment = { Dev: "http://dev.xxx.com", Test: "http://test.xxx.com", Official: "http://www.xxx.com" }
var Trace = {
AutoSubmit: false, //是否在提交表单时自动处理
Parameter: {
TraceType: ‘‘, //TraceType.open
Guid: ‘0‘,
SessionID: ‘‘,
PageUrl: ‘‘,
Description: ‘‘,
ProcessTime: ‘‘,
IsNewSite: false,
AppSys: 1,
ClientIP: ‘‘,
Environment: Environment.Official,
Extend: {}
},
MyAjax: function() {
this.xml = false;
this.GetXmlHttp = function() {
if (!this.xml && typeof XMLHttpRequest != ‘undefined‘) {
this.xml = new XMLHttpRequest();
}
else {
var MSXML = [‘MSXML2.XMLHTTP.5.0‘, ‘MSXML2.XMLHTTP.4.0‘, ‘MSXML2.XMLHTTP.3.0‘, ‘MSXML2.XMLHTTP‘, ‘Microsoft.XMLHTTP‘];
for (var i = 0; i < MSXML.length; i++) {
try {
this.xml = new ActiveXObject(MSXML[i]);
break;
}
catch (e) {//alert(e.message);
}
}
}
}
this.GetXmlHttp();
var xmlHttp = this.xml;
var ajax = this;
var callBack = null;
this.updatePage = function() {
if (xmlHttp.readyState == 4) {
var response = xmlHttp.responseText;
if (callBack != null && typeof callBack == "function") {
callBack(response);
}
}
}
this.toQueryString = function(json) {
var query = "";
if (json != null) {
for (var param in json) {
query += param + "=" + escape(json[param]) + "&"
}
}
return query;
}
//提交参数,回调函数, post、get方法
this.invoke = function(params, pageCallBack, method) {
if (xmlHttp) {
var query = "";
query += this.toQueryString(params);
query = query.substring(0, query.length - 1);
//var thisReg = new RegExp(/‘|"/gi);
//query = query.replace(thisReg, "");
callBack = pageCallBack;
if (method != null && method.toUpperCase() == "GET") {
var url = params.Environment + "/Trace.aspx?" + query;
xmlHttp.onreadystatechange = ajax.updatePage;
xmlHttp.open("GET", url, true);
xmlHttp.setRequestHeader("TraceAjax-Ver", "ver1.0");
xmlHttp.send(null);
}
else if (method != null && method.toUpperCase() == "POST") {
var url = params.Environment + "/Trace.aspx";
// xmlHttp.setRequestHeader("Content-Length",query);
xmlHttp.onreadystatechange = ajax.updatePage; //new CallClient(this);
xmlHttp.open("POST", url, true);
xmlHttp.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
xmlHttp.setRequestHeader("TraceAjax-Ver", "ver1.0");
xmlHttp.send(query);
}
else { //跨域
Trace.CreateTraceImg();
document.getElementById("traceImg").src = params.Environment + "/Trace.aspx?a=" + Math.random(1000000000) + "&" + query;
}
}
}
},
CreateTraceImg: function() {
if (!document.getElementById("traceImg")) {
document.write("<img id=\"traceImg\" style=‘display:none‘ />");
// var imgNode = document.createElement("img")
// imgNode.setAttribute("id", "traceImg")
// imgNode.style.display = "none";
// document.body.appendChild(imgNode);
}
},
Submit: function(params, pageCallBack, method) {
try {
var ajax = new Trace.MyAjax();
//校验step是否正确
// for (var i = 0; i < Step.length; i++) {
// if (params.TraceType == Step[i]) {
// alert(Step[i]);
// }
// }
ajax.invoke(params, pageCallBack, method);
}
catch (e) {
}
}
};
Trace.CreateTraceImg();

4、后端数据分析

结合前台收集的用户数据，后台初步可以完成，每一个页面的打开次数、占用时长，提交率、以及后台业务流的成功率等，通过报表形式展示数据分析界面，这样就可以监控用户行为异常、监控系统波动以及影响区域。

5、扩展

通过记录来源地址，可以更详尽的分析用户行为的流程。

通过追加页面元素的点击情况，从而计算点击率。

虽然服务器端也可以做到这些过程，但需求在不同的过程中插入众多的日志记录，进而POST到服务器端，过于繁冗！

另外跟踪服务器可对来源的数据请求验证其合法性，以及是否授权。

*注意：在Tracer的过程中，如遇采用系统方法如：绑定事件window.onload，需要注意不用覆盖了方法，避免与应用的页面冲突，可以通过来添加事件监听,eg:

AddTrigger: function() {

var list = document.getElementsByTagName("INPUT");
for (var i = 0; i < list.length; i++) {
if (list[i].type.toUpperCase() == ‘TEXT‘) {
if (list[i].addEventListener) {
list[i].addEventListener("keyup", function() { Timer.StartTimer(); }, false);
}
else {
list[i].attachEvent("onkeyup", function() { Timer.StartTimer(); });
}
}
}
}

6、关于脚本压缩

推荐采用JSA压缩工具，原因：稳定、可靠、压缩质量有保证

不过需要大家安装一下JAVA RUNTIME
