Question

我试图让我的javascript秒表在某种输入框中运行，这样如果我想改变当前计算的时间我可以编辑小时，分钟或秒。我尝试将时间包装在html标签内，但时间不会从脚本发送到框中。关于如何使这项工作更好的想法???

的Javascript

function _timer(callback)
{
    var time = 0;     //  The default time of the timer
    var status = 0;    //    Status: timer is running or stoped
    var timer_id;    //    This is used by setInterval function

    // this will start the timer
    this.start = function(interval)
    {
        interval = (typeof(interval) !== 'undefined') ? interval : 1000;

        if(status == 0)
        {
            status = 1;
            timer_id = setInterval(function()
            {
                switch(1)
                {
                    case 1:
                    if(time < 86400)
                    {
                        time++;
                        generateTime();
                        if(typeof(callback) === 'function') callback(time);
                   }
                   break;
                }
            }, interval);
        }
    }

    //  this will stop or pause the timer ex. timer.stop()
    this.stop =  function()
    {
        if(status == 1)
        {
            status = 0;
            clearInterval(timer_id);
        }
    }

    // Reset the timer to zero or reset it to your own custom time
    this.reset =  function(sec)
    {
        sec = (typeof(sec) !== 'undefined') ? sec : 0;
        time = sec;
        generateTime(time);
    }
    // This methode return the current value of the timer and sends it to the database
    this.getTime = function()
    {
        return time;
    }
    // This methode return the status of the timer
    this.getStatus
    {
        return status;
    }

    // This methode will render the time variable to hour:minute:second format
    function generateTime()
    {
        var second = time % 60;
        var minute = Math.floor(time / 60) % 60;
        var hour = Math.floor(time / 3600) % 60;

        second = (second < 10) ? '0'+second : second;
        minute = (minute < 10) ? '0'+minute : minute;
        hour = (hour < 10) ? '0'+hour : hour;

        $('div.timer span.second').html(second);
        $('div.timer span.minute').html(minute);
        $('div.timer span.hour').html(hour);
    }
}

var timer;

$(document).ready(function(e)
{
    timer = new _timer
    (
        function(time)
        {
            if(time == 0)
            {
                timer.stop();
            }
        }
    );
    timer.reset(0);
});

HTML

<div class="timer">
    <span class="hour"></span>:<span class="minute"></span>:<span class="second"></span>
</div>
<div>
    <button onClick="timer.start(1000)">Start</button>
    <button onClick="timer.stop()">Stop</button>
    <button onClick="timer.reset(0)">Reset</button>
</div>

Javascript，在秒表中加时间可编辑
