我有一个不太专业的代码，但它做我想要的:)。代码基本上是在商店开放计算多长时间，如果关闭计算多长时间左开窗口。现在我想用jQuery倒计时来设计它，但我找不到任何只计算小时，分钟，也许秒。我正在尝试UNIX倒计时，但不知道我做错了什么。我想请你们Stackoverflow的同胞帮我解决这个问题。
这是我的代码（不要讨厌仇恨:)）
date_default_timezone_set('Greenwich'); //Fixes my server location
$openingtime = strtotime('06:00'); //Opening time
$closingtime = strtotime('23:10'); //Closing time
$timenow = strtotime('now'); //Current Server Time
$twentyfourhours = "24:00"; //Hours in a day
//echo date('G:i', $openingtime); //Just texting
//echo date('G:i', $closingtime);
//echo date('H:i', $timenow);
//echo $twentyfourhours;// Testing ends here
$openingin = $twentyfourhours - $timenow + $openingtime; //24:00 - 23:20 + 6:00 = How long left for opening
$closingdown = $closingtime - $timenow; //23:10 - 23:20 How long left to close
//If current time value is bigger then closing time then display when the shop will re-open again
if (date('H:i', $timenow) > date('H:i', $closingtime))
{
echo "The shop will be open in ".date('H:i', $openingin)." hours";
}
//If current time value is lower then closing time then display how long the shop will stay open
elseif (date('H:i', $timenow) < date('H:i', $closingtime))
{
echo "The shop will be open for ".date('H:i', $closingdown)." hours";
}
答案 0 :(得分：0)
好的，我已经设法找到一个，但现在如果你要去My Testing Ground你会注意到秒而不是从60开始倒计时他们从00,99,98,97,97开始并且一路走来下来:(不知道为什么会发生我m attaching JS code
