我制作了两个秒表来跟踪用户的活动，一个人在另一个人开始/恢复时暂停。但它每次从其他时钟获得时间。请帮我纠正，或者请建议任何更好的方法，我想一起使用10秒表来跟踪活动，并希望我的所有秒表在一侧，按钮在另一侧。提前谢谢。
$(document).ready(function(){
var clocDiv = '';
$(".act-butn").button().click(function(){
var act = $(this).attr('value');
clocDiv = '#'+act+' span';
prev_hours = parseInt($(clocDiv).eq(0).html());
prev_minutes = parseInt($(clocDiv).eq(1).html());
prev_seconds = parseInt($(clocDiv).eq(2).html());
prev_milliseconds = parseInt($(clocDiv).eq(3).html());
updateTime(prev_hours, prev_minutes, prev_seconds, prev_milliseconds);
});
// Update time in stopwatch periodically - every 25ms
function updateTime(prev_hours, prev_minutes, prev_seconds, prev_milliseconds){
var startTime = new Date(); // fetch current time
timeUpdate = setInterval(function () {
var timeElapsed = new Date().getTime() - startTime.getTime(); // calculate the time elapsed in milliseconds
// calculate hours
hours = parseInt(timeElapsed / 1000 / 60 / 60) + prev_hours;
// calculate minutes
minutes = parseInt(timeElapsed / 1000 / 60) + prev_minutes;
if (minutes > 60) minutes %= 60;
// calculate seconds
seconds = parseInt(timeElapsed / 1000) + prev_seconds;
if (seconds > 60) seconds %= 60;
// calculate milliseconds
milliseconds = timeElapsed + prev_milliseconds;
if (milliseconds > 1000) milliseconds %= 1000;
// set the stopwatch
setStopwatch(hours, minutes, seconds, milliseconds);
}, 25); // update time in stopwatch after every 25ms
}
// Set the time in stopwatch
function setStopwatch(hours, minutes, seconds, milliseconds){
$(clocDiv).eq(0).html(prependZero(hours, 2));
$(clocDiv).eq(1).html(prependZero(minutes, 2));
$(clocDiv).eq(2).html(prependZero(seconds, 2));
$(clocDiv).eq(3).html(prependZero(milliseconds, 3));
}
// Prepend zeros to the digits in stopwatch
function prependZero(time, length) {
time = new String(time); // stringify time
return new Array(Math.max(length - time.length + 1, 0)).join("0") + time;

答案 0 :(得分：2)
代码，＆＃39; id＆＃39;是唯一的，你不应该多次使用相同的id。
我在这里做的有两个部分， 第一部分是秒表，你可以创建你想要的尽可能多的秒表。只需复制更多<span class="basic stopwatch">Watch x</span>，但请确保您拥有相同数量的btngroup和watchgroup
下面的第二部分将动态驱动所有时钟，启动一个将暂停所有其他时钟：
//click one btn, stop all other watch
$('#btngroup button').live('click', function() {
var btnClicked = $(this).index();
$('.basic').each(function(index) {
if(btnClicked == index){
$(this).find('a:eq(0)')[0].click();
} else {
$(this).find('a:eq(1)')[0].click();
}
});
});
许多代码，玩耍并且应该符合您的需求
// stopwatch functions...
