私のe-examのカウントダウンタイマーが機能しなくなったので、実際に何が起こったのか理解できなかった。ゼロを読み（hh：分：秒）、質問に答えることなく学生の質問を自動的に提出し、それによって学生（学生）を0％に格付けします。おかげで...タイマーは学生が試験を試みることを許可せずに質問を提出することによってすぐに開閉する。
function countDown()
{
sec--;
if (sec == -01) {
sec = 59;
min = min - 1;
if(min==-01)
{
min=59;
hour=hour-1;
}else
{
hour=hour;
}
} else {
min = min;
}
if (sec<=9) { sec = "0" + sec; }
time = (hour<=9 ? "0" + hour : hour) + " : " + (min<=9 ? "0" + min : min) + " : " + sec + "";
if (document.getElementById) { document.getElementById('timer').innerHTML = time; }
SD=window.setTimeout("countDown();", 1000);
if (hour=='00'&& min == '00' && sec == '00') { sec = "00";min="00"; window.clearTimeout(SD); window.location=document.forms[0].action+"?fs=yes";}
}
function addLoadEvent(func) {
var oldonload = window.onload;
if (typeof window.onload != 'function') {
window.onload = func;
} else {
window.onload = function() {
if (oldonload) {
oldonload();
}
func();
}
}
}
addLoadEvent(function() {
countDown();
});

変数が宣言された後、ありがたいことですが、まだ動作しません。 – user6458234
あなたはcountDown関数のデバッグを試して、あなたのsec、min、hour変数の値が何であるかを見てきましたか？ –
はい、私はしましたが、それでもまだ動作していないか、またはパラパラのメインスクリプトをコピーしていますので、ソリューションがあれば見えますか？ – user6458234
