Question

我有一个JavaScript计数器，该计数器应该适用于所有注释，但是当我发布新注释时，该按钮会显示在所有注释上，但是当我单击其他注释上的按钮时，计数器的编号只会显示在顶部注释中。

我也有一个名为“ comments”的评论表

我不知道为什么该按钮无法正常运行，因为我在每个注释上都使按钮回显，因此该功能不应仅一次运行

表结构为：

cid - int(11)

uid - varchar(128)latin1_swedish_ci 

date - datetime

message - mediumtext latin1_swedish_ci

<?php
function setComments($conn) {
   if (isset($_POST['commentSubmit'])) {
       $uid = $_POST['uid'];
       $date = $_POST['date'];
       $message = $_POST['message'];
       $message = preg_replace (
    "/(?<!a href=\")(?<!src=\")((http|ftp)+(s)?:\/\/[^<>\s]+)/i",
    "<a href=\"\\0\" target=\"blank\">\\0</a>",
    $message
);
     $sql = "INSERT INTO comments (uid, date, message) VALUES ('".mysqli_real_escape_string($conn,$uid)."','".mysqli_real_escape_string($conn,$date)."','".mysqli_real_escape_string($conn,$message)."')";
     $result = $conn->query($sql);
     }
 } 


function getComments($conn) {
  $sql = "SELECT * FROM comments";
  $result = $conn->query($sql);
  while($row = $result->fetch_assoc()) {
    $id = $row['uid'];
    $sql2 = "SELECT * FROM users WHERE id='$id'";
    $result2 = $conn->query($sql2); 
    if ($row2 = $result2->fetch_assoc()) {

我的计数器仅适用于我的第一条评论，不适用于我的第二条评论
