我有一個有多個比賽的小livescore頁面，每個比賽在數據庫中有唯一的id。我使用AJAX將數據提交到數據庫，以避免頁面刷新。問題在於AJAX無法識別我提交（更新）數據（分數）的匹配，並始終從第一個表（匹配）發送標識。如果我使用PHP在同一個文件中的代碼工作正常，但頁面需要重裝：阿賈克斯沒有得到唯一的ID
$queryAPTChallenge = mysqli_query($server, "SELECT * FROM meciurilive WHERE Turneu='APT Challenge'");
while ($row = mysqli_fetch_array($queryAPTChallenge)) {
$id=$row['id'];
$submitj1='submitj1'.$id;
$jucator1=$row['Jucator1'];
$jucator2=$row['Jucator2'];
$ziua=$row['Ziua'];
$ora=$row['Ora'];
$set1j1=$row['Set1j1'];
$set1j2=$row['Set1j2'];
$set2j1=$row['Set2j1'];
$set2j2=$row['Set2j2'];
$set3j1=$row['Set3j1'];
$set3j2=$row['Set3j2'];

請留意代碼格式化並儘量避免使用水平滾動條。 – reporter
