Flipclock js倒计时1小时无需重置

Flipclock js countdown 1hour without reset

我正在尝试在不重置刷新时间的情况下进行倒计时。我只需要倒计时 1 小时,但我不希望它在刷新时重置。从服务器获取当前时间和过期时间不起作用,因为我想通过单击重置该计时器。这是我当前的 js 代码:

<script>
    var clock;


    clock = $('.clock').FlipClock({
        clockFace: 'HourlyCounter',
        autoStart: false,
        callbacks: {
            stop: function() {
                $('.message').html('The clock has stopped!')
            },
        }
    });   
    clock.setTime(3600);
    clock.setCountdown(true);
</script>

是的,您可以根据您的示例使用 flipclock and jquery-cookie take a look at 1 minute countdown Example.

flipclockinit() 功能中,将结束日期存储在 cookie 中,使用 clock.setTime() 初始化计时器,使用 clock.setCountdown(true) 启用倒计时,并使用 [=18= 启动它].

现在如果用户刷新页面,我们将定时器设置为当前日期和结束日期之间的差异,这样计数器就可以正常继续倒计时:

var counter = $.cookie('endDate')-currentDate;
clock.setTime(counter);

点击 reset 按钮将通过删除 cookie endDate 和初始化倒计时功能来重置计数器。

HTML :

<div class="clock" style="margin:2em;"></div>
<div class="message"></div>
<button id='reset'>Reset</button>

Js :

//ready function
$(function(){

    countDown = function(){
        var currentDate = Math.round(new Date() / 1000);

        var clock = $('.clock').FlipClock({
            countdown: true,
            callbacks: {
                init: function() {
                    //store end date If it's not yet in cookies
                    if(!$.cookie('endDate')){
                        // end date = current date + 1 minutes
                        var endDate = Date.now() + 1*60*1000; 

                        // store end date in cookies
                        $.cookie('endDate', Math.round(endDate / 1000)); 
                    }
                },
                stop: function() {
                    $('.message').html('The clock has stopped!');
                },
            }
        });

        /* counter will be at first 1 min if the user refresh the page the counter will 
           be the difference between current and end Date, so like this counter can 
           continue the countdown normally in case of refresh. */
        var counter = $.cookie('endDate')-currentDate;

        clock.setTime(counter);
        clock.setCountdown(true);

        clock.start();
    }

    //reset button
    $('#reset').click(function(){
        $.removeCookie('endDate'); //removing end date from cookies
        countDown(); //launch countdown function
    });

    //Lanching count down on ready
    countDown();
});

在您的情况下(1 小时),您只需将这一行中的 1 替换为 60 即可:

var endDate = Date.now() + 1*60*1000; // For you .... + 60*60*1000
