Question

我用php编写了一个带有tr和td标记的表中的计时器，下面的代码显示了它

$time_now=time();
$time_check=$fetch_time ['time_vam_give']+($durday1*24*60*60);
$remaining=$time_check-$time_now;
$time_remain_day=floor(($remaining)/(24*60*60));
$hours_remaining = floor(($remaining % 86400) / 3600);
$minute_remainig=floor((($remaining % 86400) % 3600)/60);
$second_reminig=((($remaining % 86400) % 3600)%60);
Echo “<table><tr class='tr1' style='background-color: #CC8A10' >
<td class='td1' style='background-color: #CC8A10'>Day</td>
<td class='td1' style='background-color: #CC8A10'>Hour</td>
<td class='td1' style='background-color: #CC8A10'>Minute</td>
<td class='td1' style='background-color: #CC8A10'>Second</td></tr>
 <tr class='tr1'><td class='td1' style='background-color: #FC1359'>$time_remain_day</td>
<td class='td1' style='background-color: #FC1359'>$hours_remaining</td>
<td class='td1' style='background-color: #FC1359'>$minute_remainig</td>
<td class='td1' style='background-color: #FC1359'>$second_reminig</td></tr>”;

为了刷新我有一个刷新所有页面的代码

$page = $_SERVER['PHP_SELF'];
$sec = "5";
header("Refresh: $sec; url=$page");

但是刷新代码，刷新所有页面和所有对象都应该刷新，我只想要包含Time的变量的表中的代码，我该怎么办呢？另外我使用Iframe但是使用这个标签，例如页面的屏幕截图，它不适合和漂亮。

echo " <iframe id='dynamic-content' src='../function/Func1.php' ></iframe>";

最诚挚的问候。

刷新而不重新加载你应该使用ajax

你可以使用这样的东西

将2个php文件设为第一个 index.php

<script src="http://code.jquery.com/jquery-latest.js">

</script>
<script>
    $(document).ready(function(){
     setInterval(ajaxcall, 1000);
 });
 function ajaxcall(){
     $.ajax({
         url: 'gettime.php',
         success: function(data) {
             data = data.split(':');
             $('#days').html(data[0]);
             $('#hours').html(data[1]);
             $('#minutes').html(data[2]);
             $('#seconds').html(data[3]);
         }
     });
 }
</script>

<table>
    <tr class='tr1' style='background-color: #CC8A10'>
        <td class='td1' style='background-color: #CC8A10'>Day</td>
        <td class='td1' style='background-color: #CC8A10'>Hour</td>
        <td class='td1' style='background-color: #CC8A10'>Minute</td>
        <td class='td1' style='background-color: #CC8A10'>Second</td>
    </tr>
    <tr class='tr1'>
        <td class='td1' style='background-color: #FC1359'><span id="days">0</span></td>
        <td class='td1' style='background-color: #FC1359'><span id="hours">0</span></td>
        <td class='td1' style='background-color: #FC1359'><span id="minutes">0</span></td>
        <td class='td1' style='background-color: #FC1359'><span id="seconds">0</span></td>
    </tr>
</table>

和 gettime.php

<?php    
$time_now=time();
$time_check=$fetch_time ['time_vam_give']+($durday1*24*60*60);
$remaining=$time_check-$time_now;

$time_remain_day=floor(($remaining)/(24*60*60));
$hours_remaining = floor(($remaining % 86400) / 3600);
$minute_remainig=floor((($remaining % 86400) % 3600)/60);
$second_reminig=((($remaining % 86400) % 3600)%60);

echo $time_remain_day . ':' . $hours_remaining . ':' . $minute_remainig . ':' . $second_reminig; 
?>

我希望能帮到你

如何刷新页面或页面块的PHP没有重新编码？
