嗨,我从以下位置获得了倒数计时器代码:
https://codepen.io/SitePoint/pen/MwNPVq ,
并修改为:
function getTimeRemaining(endtime) {
var t = Date.parse(endtime) - Date.parse(new Date());
var seconds = Math.floor((t / 1000) % 60);
var minutes = Math.floor((t / 1000 / 60) % 60);
return {
'total': t,
'minutes': minutes,
'seconds': seconds
};
}
function initializeClock(id, endtime) {
var clock = document.getElementById(id);
var minutesSpan = clock.querySelector('.minutes');
var secondsSpan = clock.querySelector('.seconds');
function updateClock() {
var t = getTimeRemaining(endtime);
minutesSpan.innerHTML = ('0' + t.minutes).slice(-2);
secondsSpan.innerHTML = ('0' + t.seconds).slice(-2);
if (t.total <= 0) {
clearInterval(timeinterval);
}
if(t.minutes == 0 && t.seconds ==0) {
console.log('in this func');
deadline = new Date(deadline.getTime() + 10*60000);
}
}
updateClock();
var timeinterval = setInterval(updateClock, 1000);
}
deadline = new Date(Date.parse('Fri Mar 30 2018 17:03:00 GMT+0530'));
initializeClock('clockdiv', deadline);
我所做的改变是,我检查了分钟和秒是否都是 0,然后变量“截止日期”应该用新的时间更新。倒数计时器工作正常,但当它达到 0:0 时,它进入函数,一切都停止了。
最佳答案
当时钟到达 0:0
( updated pen ) 时,您需要再次初始化时钟
if (t.minutes == 0 && t.seconds == 0) {
console.log('in this func');
deadline = new Date(deadline.getTime() + 10 * 60000);
initializeClock('clockdiv', deadline); //added this line
}
演示
function getTimeRemaining(endtime) {
var t = Date.parse(endtime) - Date.parse(new Date());
var seconds = Math.floor((t / 1000) % 60);
var minutes = Math.floor((t / 1000 / 60) % 60);
var hours = Math.floor((t / (1000 * 60 * 60)) % 24);
var days = Math.floor(t / (1000 * 60 * 60 * 24));
return {
'total': t,
'days': days,
'hours': hours,
'minutes': minutes,
'seconds': seconds
};
}
function initializeClock(id, endtime) {
var clock = document.getElementById(id);
var daysSpan = clock.querySelector('.days');
var hoursSpan = clock.querySelector('.hours');
var minutesSpan = clock.querySelector('.minutes');
var secondsSpan = clock.querySelector('.seconds');
function updateClock() {
var t = getTimeRemaining(endtime);
daysSpan.innerHTML = t.days;
hoursSpan.innerHTML = ('0' + t.hours).slice(-2);
minutesSpan.innerHTML = ('0' + t.minutes).slice(-2);
secondsSpan.innerHTML = ('0' + t.seconds).slice(-2);
if (t.total <= 0) {
clearInterval(timeinterval);
}
if (t.minutes == 0 && t.seconds == 0) {
console.log('in this func');
deadline = new Date(deadline.getTime() + 10 * 60000);
initializeClock('clockdiv', deadline); //added this line
}
}
updateClock();
var timeinterval = setInterval(updateClock, 1000);
}
var deadline = new Date(Date.parse(new Date()) + 1 * 1 * 1 * 6 * 1000);
initializeClock('clockdiv', deadline);
