用ajax实现的自动投票的代码_javascript技巧

我于是做了下面一段代码，做成任务管理器，每隔1分钟打开一次，再自动关闭窗口，但实际运行下来，却无效果，不知问题出在哪里？

复制代码 代码如下:

<script> <BR>var CheckFreq=1;//队列检查频率，默认1秒检查一次 <BR>var bRun=false;//防止同一时间同时运行２个程序 <BR>function RunUrl(strUrl,strFreq) <BR>{ <BR> this.url=strUrl;//运行的URL <BR> this.freq=strFreq;//运行频率 <BR> this.lastrun='';//上次运行时间 <BR>} <BR>var RunQueue = new Array(); <BR>function AddRun(strUrl,strFreq)//添加Run <BR>{ <BR> if(strUrl==''||strFreq=='')return <BR> RunQueue[RunQueue.length]=new RunUrl(strUrl,strFreq) <BR>} <BR>function Run(url)//运行url <BR>{ <BR> var xmlHttp; <BR> if (window.XMLHttpRequest)xmlHttp = new XMLHttpRequest(); <BR> else if (window.ActiveXObject)xmlHttp = new ActiveXObject("Microsoft.XMLHTTP"); <BR> xmlHttp.onreadystatechange = function(){bRun=false;} <BR> xmlHttp.open("GET", url, true); <BR> xmlHttp.send(null); <BR> bRun=true; <BR>} <BR>function CheckRun()//检查队列 <BR>{ <BR> var dtNow=new Date(),objRun; <BR> var tNow=dtNow.getTime(); <BR> for(var i=0;i<RunQueue.length;i++) <BR> { <BR> objRun=RunQueue[i]; <BR> if(objRun.lastrun=='')objRun.lastrun=tNow; <BR> if(!bRun&&(objRun.freq==0||(tNow-objRun.lastrun)>objRun.freq*1000)) <BR> { <BR> objRun.lastrun=tNow; <BR> Run(objRun.url); <BR> } <BR> } <BR>} <BR>AddRun('http://publish.sina.com.cn/poll.php?p_id=413&t_id=119',10); <BR>setInterval('CheckRun()',CheckFreq*1000);//setInterval <BR></script>

<script> <BR><!-- <BR>function clock(){ <BR> i=i-1 <BR> document.title="After "+i+" minitues,this window will closed self!"; <BR> if(i>0)setTimeout("clock();",20000); <BR> else {window.opener=null;self.close();} <BR>} <BR>var i=2 <BR>clock(); <BR>--> <BR></script>

<script language="javascript"> //By Ayi 2007-2-10 var CheckFreq=1;//队列检查频率，默认1秒检查一次 var bRun=false;//防止同一时间同时运行２个程序 function RunUrl(strUrl,strFreq) { this.url=strUrl;//运行的URL this.freq=strFreq;//运行频率 this.lastrun='';//上次运行时间 } var RunQueue = new Array(); function AddRun(strUrl,strFreq)//添加Run { if(strUrl==''||strFreq=='')return RunQueue[RunQueue.length]=new RunUrl(strUrl,strFreq) } function Run(url)//运行url { var xmlHttp; if (window.XMLHttpRequest)xmlHttp = new XMLHttpRequest(); else if (window.ActiveXObject)xmlHttp = new ActiveXObject("Microsoft.XMLHTTP"); xmlHttp.onreadystatechange = function(){bRun=false;} xmlHttp.open("GET", url, true); xmlHttp.send(null); bRun=true; } function CheckRun()//检查队列 { var dtNow=new Date(),objRun; var tNow=dtNow.getTime(); for(var i=0;i<RunQueue.length;i++) { objRun=RunQueue[i]; if(objRun.lastrun=='')objRun.lastrun=tNow; if(!bRun&&(objRun.freq==0||(tNow-objRun.lastrun)>objRun.freq*1000)) { objRun.lastrun=tNow; Run(objRun.url); } } } AddRun('http://publish.sina.com.cn/poll.php?p_id=413&t_id=119',10); setInterval('CheckRun()',CheckFreq*1000);//setInterval </script> <script language="javascript"> <!-- function clock(){ i=i-1 document.title="After "+i+" minitues,this window will closed self!"; if(i>0)setTimeout("clock();",20000); else {window.opener=null;self.close();} } var i=2 clock(); --> </script>
