我目前正在开发一款使用jquery和javascript的Simon说型游戏。
我已经在github上链接了游戏的完整副本
Github下载并解压缩以完全看到游戏 https://github.com/Jamiex304/Simon_Says_Game_Demo （现已停用）
我遇到了一个问题，我想添加一个玩家可以看到的计时器？
目前，该级别将继续，直到用户点击序列中的错误按钮。
有关游戏的一些基本信息 用户将看到每个级别的随机序列，新的序列被添加一个额外的移动 每次用户输入正确的序列时，他们都会进入下一级别 所有信息都可以在随附的带注释的JavaScript中找到
我想要帮助添加
我只想在用户点击开始按钮时添加一个以10秒开始的计时器 每次输入正确的序列时，计时器再次启动 当他们达到5个正确的序列时，计时器会增加5秒，所以
我附加了处理游戏事件的JavaScript，并且有一个指向完整网站的链接
任何帮助都会很棒

除了定时器之外，你没有真正说出你想要的东西，但基于你的标记就是这样的东西你正在寻找什么？
var $timer = $('.Timer'),
$timerTitle = $('.TimerTitle'),
$start = $('.start'),
$increment = $('.increment'),
maxDuration = 10,
defaultDuration = 10,
count = 0,
$gameCount = $('#gameCount');
$timerTitle.text("Get ready! You have " + maxDuration + " seconds!");
$start.on('click', function()
{
getDuration();
return false;
});
function getDuration()
{
$start.prop('disabled', true);
setTimeout(function()
{
var duration = $timer.data('duration');
if(duration === undefined || duration < 0)
duration = maxDuration;
$timer.text(duration);
$timer.data('duration', --duration);
if(duration > -1)
{
if(duration < 5)
{
if(duration % 2 == 0)
{
$timer.css({'background-color':'blue', 'color':'white'});
}
else
{
$timer.css({'background-color':'transparent', 'color':'black'});
}
}
getDuration();
}
else
{
count++;
$gameCount.text("Current game count: " + count);
if(count % 5 == 0)
defaultDuration += 5;
maxDuration = defaultDuration;
$timer.css({'background-color':'transparent', 'color':'black'});
$timer.text('');
$timerTitle.text("Get ready! You have " + maxDuration + " seconds!");
$start.prop('disabled', false);
}
}, 1000);
}<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.0.0/jquery.min.js"></script>

它有点不同寻常（它不会倒计时，但不能倒计时），但是如何：
http://jsfiddle.net/rudiedirkx/nrp3e269/
魔法是tick()，触发60 / s：
var tickStart = 0;
function tick() {
var tickSpent = (Date.now() - tickStart) / 1000,
timeLeft = startTimeLeft - tickSpent;
tl.textContent = Math.round(timeLeft * 10) / 10;
if ( timeLeft > 0 ) {
requestAnimationFrame(tick);
}
else {
document.body.classList.add('gameover');
}
}
开始按钮开始计算：
tickStart = Date.now();
tick();
移动按钮为计数增加了时间：
if ( ++moves % 5 == 0 ) {
startTimeLeft += 5;
}
else {
startTimeLeft += 1;
}
它只是一个概念证明。你将不得不做大头。首先要做的是使用方法和局部属性而不是全局变量来使它成为一个很好的CountDown对象。
CountDown.startTimeLeft
CountDown.tickStart
CountDown.tick()
CountDown.start()
CountDown.finish()
CountDown.addTime()
将您的应用逻辑与自动收报机分开。

这样的事可能有用吗？
var n = 100;
setTimeout(countDown,1000);
function countDown(){
n--;
if(n > 0){
setTimeout(countDown,1000);
}
$(".timer").html(n);
}
答案 4 :(得分：-2)
如果我明白你只想倒计时？从10秒开始等等？ 比这个脚本会帮助你我想
<script>
<!--
//change below target URL to your own OTHERWISE DELETE
// this link will redirect you to the main page or the page you want
var targetURL="example.com"
//change the second to start counting down from
var countdownfrom=10
var currentsecond=document.redirect.redirect2.value=countdownfrom+1
function countredirect(){
if (currentsecond!=1){
currentsecond-=1
document.redirect.redirect2.value=currentsecond
}
else{
window.location=targetURL
return
}
setTimeout("countredirect()",1000)
}
countredirect()
//-->
</script>
