这是一个利用javascript管理超时的小模型.在实现此项目时，我将使用jQuery扩展javascript功能并易于使用.不过，作为概念的简单证明就足够了:
This is a small mockup utilizing javascript to manage the time out. When realizing this project I''d use jQuery for extended javascript functionality and ease of use. Nevertheless as a simple proof of concept it suffices:
<html>
<head>
<script type="text/javascript">
function hideQuestions()
{
// Hide the questions
document.getElementById("answerBlock").style.display = "none";
// Show the message that the questions timed out
document.getElementById("quicker").style.display = "block";
}
function checkTime()
{
secondsLeft = secondsLeft - 1;
if(secondsLeft <= 0)
{
hideQuestions();
//alert("Time is up!");
document.getElementById("secondsLeft").style.color = "red";
window.clearInterval(myTimer);
writeTime("Timed out!");
// Here you'd probably want to do a redirect to another page
}
else
{
writeTime(secondsLeft + "s");
}
}
function writeTime(msg)
{
document.getElementById("secondsLeft").innerHTML = msg;
}
</script>
</head>
<body onload="">
<h1>Timeout Exam Question: <span id="secondsLeft"></span></h1>
<div id="answerBlock">
<input id="answer1" name="answer1" type="text" /><br/>
<input id="answer2" name="answer1" type="text" /><br/>
<input id="answer3" name="answer1" type="text" /><br/>
<input id="answer4" name="answer1" type="text" /><br/>
<input type="button" name="submit" value="Answer Questions"/>
</div>
<div id="quicker" style="display:none;">
You must answer more quickly next time!
</div>
</body>
<script>
var secondsLeft = 10;
writeTime(secondsLeft + "s");
var myTimer = window.setInterval(checkTime, 1000);
</script>
</html>

ajax计时器最适合您的项目.尝试一下，看看有什么用.
ajax timer is the best fit for your project.Try it and see how much it is helpful.
一分钟?嗯那么，一个旁注:没有人需要使用这种测试来测试知识"吗?什么，你在训练猴子吗?
万一有人不理解:基于变体选择进行测试是将学生教育"成白痴的方式；有些已经受过教育".我不在乎这是一个要求":在集中营杀害囚犯的人也确实满足了要求".基于这种测试的教育系统是一种集中营和种族灭绝.现在，随心所欲地投票.

One minute? Hm. One side note then: nobody needs the "knowledge" tested using such kind of tests? What, are you training monkeys?
In case somebody did not understand it: testing based on choice of variants is the way to "educate" students into idiots; some are already "educated". I don''t care this is a "requirement": people who killed prisoners in concentration camps also did to meet the "requirements". Education system based on such tests is a kind of concentration camps and genocide. Now, down-vote as much as you want.
