收集使用者隱私的行徑眼下已不再是什麼新鮮的話題（與其說是收集，不如說是偷窺），就連G、MS也屢出風頭，當然事出有因，企業通過無法八門的各種手段瞭解使用者的行為，進而作為決策支援的依據；通常表現為跨領域的收集（瀏覽器、智慧系統、OS etc.）、業務、產品資料的收集，當然收集的方式也不一而論。以下展示通過客戶端指令碼方式收集Web站點使用者行為資料的實現方式，以此來判斷頁面載入過程、執行時間、使用者停留時間、頁面提交率、成功率、頁面錯誤等（本示例實現較為簡單，在特定複雜的業務資料收集時，可適當重構與改造）。

1、收集基礎資料

基礎資料涵蓋

（1）  業務類：業務流頁面地址、使用者停留時間、開啟次數、

會話ID、客戶端IP、業務流步驟等

（2）  輔助類：瀏覽器、OS、COOKIE等

（3）  示例

2、時間統計

通過在頁面放置計時器，計算當前檢視下使用者的停留時間。

示例：

/*--------Timer Script------------- 
*  
* 頁面計時器控制元件 
* 1、Timer.BindControl = 'inputTimer'; 
* 2、<input id="inputTimer" type="hidden" class="timer" /> 
* 不寫Cookie、不顯示定時器時,採用(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;  
        //每個頁面單獨記錄,不需要採用Cookie,遮蔽  
        //        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);  
    },  
    //重新開始計時  
    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")) {

    }  
}  
/* 相容兩種模式設定Cookie */  
//$(window).unload(function() { Timer.SetValue(); });  
//$("form").submit(function() { Timer.SetValue(); });  
 

3、非同步記錄

將收集到的資料通過GET、POST非同步的方式傳送到目標伺服器

示例： 

/*--------Trace Script-------------*/  
var Step =  
{  
    /* step */  
    step1: "step1", //第一步開啟,不含歷史返回、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", //操作失敗  
    errstep1: "errstep1", //第一步出錯 錯誤頁面記錄  
    errstep2: "errstep2",  
    errstep3: "errstep3",  
    errstep1ret: "errstep1ret", //出錯頁返回到第一步  
    errstep2ret: "errstep2ret",  
    errstep3ret: "errstep3ret",  
    /* login */  
    loginb1: "loginb1", //銀行卡登入返回  
    loginc1: "loginc1", //實物卡登入返回  
    loginbind: "loginbind", //一點充登入返回  
    step1login: "step1login", //第一步登入介面  
    /* other */  
    bind: "bind", //使用者繫結一點充  
    mobile: "mobile", //修改手機號  
    password: "password", //修改密碼  
    cancelbind: "cancelbind", //取消服務  
    Login: "Login", //使用者登入日誌  
    querydeposit: "querydeposit", //充值記錄  
    querycardbalance: "querycardbalance", //實物卡餘額  
    clickkf: "clickkf", //點選線上客服  
    closekf: "closekf", //關閉線上客服  
    clickaccount1: "clickaccount1", //點選新增常用賬號

4、後端資料分析

結合前臺收集的使用者資料，後臺初步可以完成，每一個頁面的開啟次數、佔用時長，提交率、以及後臺業務流的成功率等，通過報表形式展示資料分析介面，這樣就可以監控使用者行為異常、監控系統波動以及影響區域。

5、擴充套件

通過記錄來源地址，可以更詳盡的分析使用者行為的流程。

通過追加頁面元素的點選情況，從而計算點選率。

雖然伺服器端也可以做到這些過程，但需求在不同的過程中插入眾多的日誌記錄，進而POST到伺服器端，過於繁冗！

另外跟蹤伺服器可對來源的資料請求驗證其合法性，以及是否授權。

*注意：在Tracer的過程中，如遇採用系統方法如：繫結事件window.onload，需要注意不用覆蓋了方法，避免與應用的頁面衝突，可以通過來新增事件監聽,eg:

[javascript] view plaincopy

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、關於指令碼壓縮

推薦採用JSA壓縮工具，原因：穩定、可靠、壓縮質量有保證

不過需要大家安裝一下Java RUNTIME
