倒數計時器應繼續兩個PHP頁面

Question

這是倒數計時器

<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> 

我想這個計時器將持續兩個PHP頁面，而無需再次重新啓動代碼。當每個問題顯示時，定時器不應該重新啓動。 test1.php頁面有全部的選擇題答案和test2.php頁面都有填空題答案。在我的應用程序中，首先運行test1.php（即MCQ），然後運行所有MCQ test2.php。我怎樣才能爲這兩個頁面使用相同的計時器。

Answer 1

我現在在PHP中遇到了類似的問題，並找出瞭解決方案。我不確定以下是否有幫助，但請嘗試是否適用於您。

將開始時間保存爲會話變量 在每個問題顯示之前，執行if函數以將差異更新爲「結束」和「會話[」時間「]」之間的差異。

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(); 
}
