<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />

<script>
setInterval(function(){chrono('t');},1000);

<?php
include('function.php');
session_start();
global $list;


$list= captcha_list($_SESSION['id']);
if (isset($_POST['know'])){
?>
<script>
inte = 0;
var string ='<?php
$str='';
 $x=sizeof($list);

      for($j=0;$j < $x;$j++)
    { 

     for($i=0;$i < 7;$i++)
    { 

          $str=$str.$list[$j][$i].';'; 
          }
     } 
echo $str.$list[$x-1];
?>';
var count='<?php 
$x1=sizeof($list);

var table =string.split(';');
var longuer=table.length-1;
currentElement=15;
document.getElementById("im").src=table[currentElement];

图像一个接一个地传递，但如果我单击“知道”按钮，页面刷新并显示第一张图像。我想如果我点击“知道”下一个图像将显示。

  1. 错误是什么？
  2. 我该如何解决？
