问题描述
您好，
我不是js程序员，但我希望找到一个预先编写的脚本
，我可以使用它。所有我需要的是一个简单的计数器计时器，
有一个开始，暂停和停止控制，我找到了一些，但是他们
似乎都重置了一次你把它们暂停了，我需要它停留在它的位置，然后一旦有人点击
重新开始，它就会从暂停的点继续。
如果有人知道我在哪里可以找到这样的东西我会很感激
它。
谢谢

如果你想要一个合理准确计算秒数的计数器，你需要使用一个日期对象并每50ms左右运行一次计数器获取
系统时间并使用它来计算大致相等的秒数。
如果你只想要一个大约每100ms运行一次的计数器和时间
准确性并不重要，那么下面的脚本就可以完成这项工作。
< script type =" text / javascript">

var pageCounter =（function（）
{
var counterLag = 100; //更新之间的毫秒数
var counterValue = 0; //初始值
var counterRef; //对当前计时器的引用
var textElement; //显示值的元素
返回{
//初始化值并启动计时器如果没有
//已经运行了。不要把计数器归零
start：function（id）
{
if（！document.getElementById）return;
textElement = document.getElementById（id）;
if（！textElement）return;
if （！counterRef）pageCounter.run（）;
}，
//运行计数器 - 使用setTimeout自行调用
//合理定期更新计数器。
run：function（）
{
textElement.innerHTML = counterValue ++;
counterRef = setTimeout（''pageCounter.run（）''，counterLag）;
}，
//停止柜台但不要零点柜台
停止：功能（）
{
if（counterRef）clearTimeout（counterRef）;
counterRef = null;
}，
//停止并将计数器归零
clear：function（）
{
if（counterRef）pageCounter.stop（）;
counterValue = 0;
textElement.innerHTML = counterValue;
}
}
}）（）;

是的，我需要有一些非常准确的东西，我需要它在一秒钟或一秒钟之内成为
3分钟的时间。
另一个问题：如果我将它用作countDOWN，这会更准确吗？
再次，谢谢。

Hello,
I am not a js programmer, but i was hoping to find a prewritten script
that i may be able to use. all i need is a simple count up timer that
has a start, pause, and stop control to it, i have found some, but they
all seem to reset once you pause them, and i need it to stay where it
is at and then continue from the paused point once someone hits
restart.
if anyone knows where i can find something like this i would appreciate
it.
Thank you

need to use a date object and run the counter every 50ms or so to grab
the system time and use that to count in roughly equal seconds.
If you just want a counter that runs about every 100ms or so and time
accuracy is not important, then the script below will do the job.
<script type="text/javascript">
var pageCounter = (function()
{
var counterLag = 100; // Milliseconds between updates
var counterValue = 0; // Initial value
var counterRef; // Reference to current timer
var textElement; // Element to displaying value
return {
// Initialise values and start the timer if one isn''t
// running already. Don''t zero the counter
start : function(id)
{
if (!document.getElementById) return;
textElement = document.getElementById(id);
if (!textElement) return;
if (!counterRef) pageCounter.run();
},
// Run the counter - uses setTimeout to call itself
// reasonably regularly and update the counter.
run : function()
{
textElement.innerHTML = counterValue++;
counterRef = setTimeout(''pageCounter.run()'', counterLag);
},
// Stop the counter but don''t zero the counter
stop : function()
{
if (counterRef) clearTimeout(counterRef);
counterRef = null;
},
// Stop and zero the counter
clear : function()
{
if (counterRef) pageCounter.stop();
counterValue = 0;
textElement.innerHTML = counterValue;
}
}
})();
</script>
<button onclick="pageCounter.start(''xx'')">Start</button>
<button onclick="pageCounter.stop()">Stop</button>
<button onclick="pageCounter.clear()">Clear</button>

yeah, i need to have something that is pretty accurate, i need it to be
within a second or 2 after a 3 minute period.
another question: if i were to use it as a countDOWN, would this be
more accurate?
once again, thank you.
