Javascript countdown and PHP date

本文关键字：日期 PHP 倒计时 Javascript | 更新日期: 2023-09-27

这是一个我用来生成一些倒计时的JavaScript，我的问题是JavaScript正在使用来自用户PC的日期，是否有任何方法来修改脚本，使用类似的东西:

<?php 
date_default_timezone_set('Ireland/Dublin');
$date = date('m/d/Y h:i:s A', time());?>

这是当前网站上用于在页面上显示多个倒计时的代码。

   <script type="text/javascript" language="JavaScript">//<![CDATA[

<?php
    echo 'StartCountDown("c' . $post->ID . '","' . $enddate . '")';
    ?>

  function StartCountDown(myDiv,myTargetDate)
  {
    var dthen   = new Date(myTargetDate);
    var dnow    = new Date();
    ddiff       = new Date(dthen-dnow);
    gsecs       = Math.floor(ddiff.valueOf()/1000);
    CountBack(myDiv,gsecs);
  }
  function Calcage(secs, num1, num2)
  {
    s = ((Math.floor(secs/num1))%num2).toString();
    if (s.length < 2) 
    {   
      s = "0" + s;
    }
    return (s);
  }
  function CountBack(myDiv, secs)
  {
    var DisplayStr;
    var DisplayFormat = "%%D%% %%H%%:%%M%%:%%S%%";
    DisplayStr = DisplayFormat.replace(/%%D%%/g,    Calcage(secs,86400,100000));
    DisplayStr = DisplayStr.replace(/%%H%%/g,       Calcage(secs,3600,24));
    DisplayStr = DisplayStr.replace(/%%M%%/g,       Calcage(secs,60,60));
    DisplayStr = DisplayStr.replace(/%%S%%/g,       Calcage(secs,1,60));
    if(secs > 0)
    {   
      document.getElementById(myDiv).innerHTML = DisplayStr;
      setTimeout("CountBack('" + myDiv + "'," + (secs-1) + ");", 990);
    }
    else
    {
      document.getElementById(myDiv).innerHTML = "&nbsp;SOLD OUT";
    }
  }
//]]></script>

看起来就像修改

一样简单

var dnow    = new Date();

转换成:

<?php date_default_timezone_set('Ireland/Dublin'); ?>
var dnow    = new Date( <?= time(); ?>);

您应该在SO上看看这个答案，@pimvdb编写的代码片段非常好，非常可读。很容易修改
