Question

我找到了可以运行我的秒表的代码。但我想跟随丹麦国家时区来运行我的代码。怎么样

<script type="text/javascript">
ElapsedTimeLogger = function(dateElementId, elapsedElementId, hiden, interval) {
    var container = $(elapsedElementId);
    var time = parseDate($(dateElementId).val());
    var interval = interval;
    var timer;

    function parseDate(dateString) {
        var date = new Date(dateString);
        return date.getTime();
    }

    function update() {
    var systemTime = new Date().getTime();
    elapsedTime = systemTime - time;
    container.html(prettyPrintTime(Math.floor(elapsedTime / 1000)));
$(hiden).val(prettyPrintTime(Math.floor(elapsedTime / 1000)));
}

    function prettyPrintTime(numSeconds) {
        var hours = Math.floor(numSeconds / 3600);
        var minutes = Math.floor((numSeconds - (hours * 3600)) / 60);
        var seconds = numSeconds - (hours * 3600) - (minutes * 60);

        if (hours < 10) hours = "0" + hours;
        if (minutes < 10) minutes = "0" + minutes;
        if (seconds < 10) seconds = "0" + seconds;
        var time = hours + ":" + minutes + ":" + seconds;

        return time;
    }

    this.start = function() {

        timer = setInterval(function() {update()}, interval * 1000);
    }

    this.stop = function() {
        clearTimeout(timer);
    }
}
$(document).ready(function () {

    var timeLogger = new ElapsedTimeLogger("#date", "#elapsed","#stoppedid", 1);
    timeLogger.start();

   $("#confirm").click(function() { //Stop timer upon clicking the Confirm Button 
        timeLogger.stop();

    });

});

    </script>

提前谢谢你。我无法发布另一个问题，为什么我需要编辑其他问题

Answer 1

删除disabled的{{1}}属性并为其添加input[name=stwa]属性

使用readonly为javascript节省时间

这是您的解决方案

                   document.clock.stwa.value = ((hour<=9) ? "0"+hour : hour) + " : " + ((min<=9) ? "0" + min : min) + " : " + sec;

                  if (text == "Start") { document.clock.theButton.value = "Start "; }
                  if (text == "Stop ") { document.clock.theButton.value = "Stop"; }

                  if (document.clock.theButton.value == "Start") {

                   localStorage.clear();
                }
