Javascript倒计时 [英] Javascript Countdown
问题描述
我已经在网上搜索了，但所有随时可用的内容都是您指定日期的地方，并且它会计入到该日期。我需要的是从27分43秒（以这种格式）简单倒计时从他们降落到页面时一直到0，任何人都可以获得任何片段？
I have searched the web but all the ones readily available are where you specificy a date and it counts down to that date. What I need is something which will simply count down from "27 minutes and 43 seconds" (in that format) all the way down to 0 from whenever they land on the page, anyone got any snippets available?
推荐答案
这样的事情应该可以解决问题。我很无聊，决定自己做而不是谷歌搜索。只需将分钟和秒设置在顶部，然后将onload中的倒计时调用更改为您想要更新的元素的ID。
Something like this should do the trick. I'm bored and decided to do it myself instead of Googling. Just set the minutes and seconds at the top and change the call to countdown inside the onload to the id of the element you want it to update.

if(minutes > 0) {
var minute_text = minutes + (minutes > 1 ? ' minutes' : ' minute');
} else {
var minute_text = '';
}
var second_text = seconds > 1 ? 'seconds' : 'second';
el.innerHTML = minute_text + ' ' + seconds + ' ' + second_text + ' remaining';
seconds--;
}, 1000);
