??? 需要说明的一点是GetResidentTime这个函数,google采用了img.load的方法加载了接收处理信息页面的,需要再服务器端配置将后缀为.gif或你所取的其他形式的文件使用aspx的方式编译运行.因为我原来考虑的是使用xmlHttp异步调用.但是页面退出的时候有时候不执行.所以就弃用了.代码如下: function GetResidentTime()
{
??? pageClose = new Date();
??? minutes = (pageClose.getMinutes() - pageOpen.getMinutes());
??? if(minutes < 0)
??? {
????? minutes = minutes + 60;
??? }
??? seconds = (pageClose.getSeconds() - pageOpen.getSeconds());
??? if(seconds < 0){ seconds += 60;}
??? time = (seconds + (minutes * 60));
??
//------------------------修改此处为接收链接地址 XML 异步传输------------------------------------
//???? var xmlHttp = createXMLHttpRequest();
//???? xmlHttp.open("POSt", reqURL + firstvisit.aspx?" + StrPara(), false);
//???? xmlHttp.send(null);
//----------------------------图片形式传递-------------------------------------------------------
??? if(isReturn() == false)
??? {
????? var i = new Image(1,1);
????? i.src = reqURL + "firstVisit.aspx?" + StrPara() + "&GUID=" + GUID;
????? i.onload = function() {LoadVoid();}
????? //进入页面的信息
????? if(getCookieValue("GUID") == "noCookie"){return ;}
????? i.src = reqURL + "pageView.gif?" + pageView() + "&st=" + time;
????? i.onload=function() {LoadVoid();}
??? }
??? else
??? {
????? var i=new Image(1,1);
????? i.src = reqURL + "pageView.gif?" + pageView() + "&st=" + time;
????? i.onload=function() {LoadVoid();}
??? }
}???
最后就是调用了.我使用了window.onunload = GetResidentTime
??? 传递的参数大家可以打印出来看一下.应该可以明白其意思.
??? 剩下的就是服务器端的处理了,在服务器端处理其实相当简单.取得request的值,验证并保存入数据库.现在有了数据,分析的事情就由用户按照自己的要求来处理了..补充一句,ip地址是由服务器端来取得保存的.
??? 使用的时候记得一定将其放到服务器端,然后使用<javascript language="javascript" type="text/javascript" src=服务器地址+路径+"statistics.js"> </script>???? (把文件名改成statistics.js方便记忆)
这里附上完整的代码(加上说明了)下载在附件里面.
??? 该例子我在IE,firefox,netscape下面测试都很正常.搞了一个月,总算有所成就了.但是还有很多需要改进的地方,希望做过的,感兴趣的朋友多多指点交流.
