Question

这是倒数计时器的代码

<script language="JavaScript">
<!--
var hoursleft = 0;
var minutesleft = 10;           // you can change these values to any value greater than 0
var secondsleft = 0;
var millisecondsleft = 0;
var finishedtext = "Countdown finished!" // text that appears when the countdown reaches 0
end = new Date();

end.setMinutes(end.getMinutes()+minutesleft);
end.setSeconds(end.getSeconds()+secondsleft);
end.setMilliseconds(end.getMilliseconds()+millisecondsleft);
function cd(){
    now = new Date();
    diff = end - now;
    diff = new Date(diff);
    var msec = diff.getMilliseconds();
    var sec = diff.getSeconds();
    var min = diff.getMinutes();

    if (min < 10){
        min = "0" + min;
    }
    if (sec < 10){
        sec = "0" + sec;
    }
    if(msec < 10){
        msec = "00" +msec;
    }
    else if(msec < 100){
        msec = "0" +msec;
    }
    if(now >= end){
        clearTimeout(timerID);
        document.getElementById("cdtime").innerHTML = finishedtext;
    }
    else{
    document.getElementById("cdtime").innerHTML = min + ":" + sec + ":" + msec;
    }       // you can leave out the + ":" + msec if you want...
            // If you do so, you should also change setTimeout to setTimeout("cd()",1000)
    timerID = setTimeout("cd()", 10); 
}
window.onload = cd;
//-->
</script>

我希望这个计时器能够继续两个php页面，而无需再次重启。当每个问题显示时，计时器不应再次重启。 test1.php页面有所有多项选择问题和test2.php页面都填写了空白问题来回答。在我的应用程序中，首先运行test1.php（即MCQs），并且在所有MCQ之后运行test2.php。如何为两个页面使用相同的计时器。

我现在在PHP中遇到类似的问题，并制定了解决方案。我不确定以下是否有帮助，但如果这对您有用，请尝试。

将开始时间保存为会话变量在显示每个问题之前，执行if函数以更新diff作为＆＃34; end＆＃34;之间的差异。和＆＃34;会话[＆＃34;时间＆＃34;]＆＃34;。

if(Session["time"]) {
    if(Session["time"]) < end {
        diff = end - Session["time"];
    } else {
         //perform answer submission (may be).
         }
} else {
    var d = new Date();
    Session["time"] = d.getTime();
}

倒数计时器应该继续两个php页面
