多个秒表无法正常工作

Question

我制作了两个秒表来跟踪用户的活动，一个人在另一个开始/恢复时被暂停。但是每次都从其他时钟获取时间。请帮我纠正，或者请提出任何更好的方法，我想一起使用10个秒表来跟踪活动，并希望我所有的秒表和另一个按钮都在我的面前。提前致谢。

为您的代码， 'ID' 是独一无二的，你不应该使用相同的ID超过一​​次。

我在这里做了两部分，第一部分是秒表，你可以创建尽可能多的秒表。只是复制更多<span class="basic stopwatch">Watch x</span>但要确保你有相同数量的btngroup和watchgroup

第二部分下面将推动所有时钟动态，开始一个将暂停所有其他人：

//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(); 
    } 
    }); 
}); 

大量的代码，玩耍和应满足您的需要

// stopwatch functions... 
 
var Stopwatch = function(elem, options) { 
 
    var timer = createTimer(), 
 
    startButton = createButton("start", start), 
 
    stopButton = createButton("stop", stop), 
 
    resetButton = createButton("reset", reset), 
 
    offset, 
 
    clock, 
 
    interval; 
 

 
    // default options 
 
    options = options || {}; 
 
    options.delay = options.delay || 1; 
 

 
    // append elements  
 
    elem.appendChild(timer); 
 
    elem.appendChild(startButton); 
 
    elem.appendChild(stopButton); 
 
    elem.appendChild(resetButton); 
 

 
    // initialize 
 
    reset(); 
 

 
    // private functions 
 
    function createTimer() { 
 
    return document.createElement("span"); 
 
    } 
 

 
    function createButton(action, handler) { 
 
    var a = document.createElement("a"); 
 
    a.href = "#" + action; 
 
    a.style = "display: none;"; 
 
    a.innerHTML = action; 
 
    a.addEventListener("click", function(event) { 
 
     handler(); 
 
     event.preventDefault(); 
 
    }); 
 
    return a; 
 
    } 
 

 
    function start() { 
 
    if (!interval) { 
 
     offset = Date.now(); 
 
     interval = setInterval(update, options.delay);

    function stop() { 
 
    if (interval) { 
 
     clearInterval(interval); 
 
     interval = null;

    function reset() { 
 
    clock = 0; 
 
    render(0);

    function update() { 
 
    clock += delta(); 
 
    render(); 
 
    } 
 

 
    function render() { 
 
    var h = Math.floor(clock/(1000 * 60 * 60)) % 24; 
 
    var m = Math.floor(clock/(1000 * 60)) % 60; 
 
    var s = Math.floor(clock/1000) % 60;

    if (ms < 10) { 
 
     ms = "0" + ms; 
 
    } 
 

 
    timer.innerHTML = h + ':' + m + ':' + s + '::' + ms; 
 

 
    } 
 

 
    function delta() { 
 
    var now = Date.now(), 
 
     d = now - offset; 
 

 
    offset = now; 
 
    return d; 
 
    } 
 

 
    this.start = start; 
 
    this.stop = stop; 
 
    this.reset = reset; 
 
}; 
 

 

 
var elems = document.getElementsByClassName("basic"); 
 
for (var i = 0, len = elems.length; i < len; i++) { 
 
    new Stopwatch(elems[i]); 
 
} 
 

 

 
//click one btn, stop all other watch 
 
$('#btngroup button').live('click', function() { 
 
    var btnClicked = $(this).index(); 
 
    $('.basic').each(function(index) {

});
