JavaScript倒计时，增加小时数&分钟 [英] JavaScript count down, add hours & minutes

问题描述

因此，我按以下顺序整理了以下内容(秒倒计时).但！我正在尝试增加小时&分钟也要倒数计时.理想情况下，保持相同的结构，并且仅使用纯JS.我希望输出为:

So, I have the below (seconds countdown) in good order. But! I am trying to add hours & minutes as apart of the count down as well. Ideally keeping the same structure, and just using pure JS. I would like the output to be:

此促销还剩X个小时，X分钟和X秒！

var count=30;

    var counter=setInterval(timer, 1000); //1000 will  run it every 1 second

    function timer()
    {
      count=count-1;
      if (count <= 0)
      {
         clearInterval(counter);
         return;
      }

     document.getElementById("timer").innerHTML=count + " secs"; // watch for spelling
    }

如果解决方案必须使用jQuery或其他库进行重写；没关系.只是不可取. 欢呼声和称呼.

If the solution has to be a rewrite with jQuery or another library; that's fine. Just not preferable. Cheers and Salutations for any help.

推荐答案

类似以下内容:

var count = 30;
var counter = setInterval(timer, 1000); //1000 will  run it every 1 second

function timer() {
    count = count - 1;
    if (count == -1) {
        clearInterval(counter);
        return;
    }

    var seconds = count % 60;
    var minutes = Math.floor(count / 60);
    var hours = Math.floor(minutes / 60);
    minutes %= 60;
    hours %= 60;

    document.getElementById("timer").innerHTML = hours + "hours " + minutes + "minutes and" + seconds + " seconds left on this Sale!"; // watch for spelling
}
