Question

我试图以这种格式获取两个日期之间日期差异的详细信息

var strg = '{"name1":123,"name2":123,"name3":123}';

var obj = JSON.parse(strg);

for (var i in obj){
  obj[i] = String(obj[i])
}

console.log(obj)

到目前为止这是我的代码..目前无效

0 years 2 days 1 hours 20 minutes 47 second

当前输出

<script>
    var starting_date = '2017-08-02 08:32:28';
    var closing_date= '2017-08-02 09:30:05';

    window.onload=function() {
      // Month,Day,Year,Hour,Minute,Second
      upTime(starting_date); // ****** Change this line!
    };
    function upTime(countTo) {
      //now = new Date();
      countTo = new Date(countTo);
     //difference = (now-countTo); 
      difference = (closing_date-countTo);
      days=Math.floor(difference/(60*60*1000*24)*1);
      years = Math.floor(days / 365);
      if (years > 1){ days = days - (years * 365)}
      hours=Math.floor((difference%(60*60*1000*24))/(60*60*1000)*1);
      mins=Math.floor(((difference%(60*60*1000*24))%(60*60*1000))/(60*1000)*1);
      secs=Math.floor((((difference%(60*60*1000*24))%(60*60*1000))%(60*1000))/1000*1);
      document.getElementById('years').firstChild.nodeValue = years;
      document.getElementById('days').firstChild.nodeValue = days;
      document.getElementById('hours').firstChild.nodeValue = hours;
      document.getElementById('minutes').firstChild.nodeValue = mins;
      document.getElementById('seconds').firstChild.nodeValue = secs;

      clearTimeout(upTime.to);
      upTime.to=setTimeout(function(){ upTime(countTo); },1000);
    }

    </script>

    <div id="countup">
      It's been
      <span id="years">00</span> 
      <span class="timeRefYears">years</span>
      <span id="days">00</span>
      <span class="timeRefDays">days</span>
      <span id="hours">00</span>
      <span class="timeRefHours">hours</span>
      <span id="minutes">00</span>
      <span class="timeRefMinutes">minutes</span>
      <span id="seconds">00</span>
      <span class="timeRefSeconds">second</span>
    </div>

如果我使用当前日期它可以正常工作

It's been NaN years NaN days NaN hours NaN minutes NaN second

Answer 1

尝试替换

var starting_date = '2017-08-02 08:32:28';
var closing_date= '2017-08-02 09:30:05';

用这个？

var starting_date = new Date('2017-08-02 08:32:28');
var closing_date=  new Date('2017-08-02 09:30:05');

但我建议你在here

中讨论一个时区

但如果您只是想减轻操纵日期的麻烦，请尝试使用moment.js

在您将countTo设置为Date的情况下将closing_date设置为1。也不要使用相同的变量名称：

var starting_date = '2017-08-02 08:32:28';
var closing_dateStr = '2017-08-02 09:30:05'; //append Str

function upTime(countToStr) {  //append Str
  //now = new Date();
  var countTo = new Date(countToStr);
  var closing_date = new Date(closing_dateStr);

我的假设是你从某个地方获取字符串日期，你需要转换它们，所以在调用方法之前转换它们并不是你的解决方案。

与javascript的日期差异
