Question

我有一个包含多个匹配项的实时比分页，每个匹配项在数据库中都有唯一的ID。我使用AJAX向数据库提交数据，以避免页面刷新。问题是AJAX没有识别我提交（更新）数据（得分）的匹配，并且始终从第一个表（匹配）发送id。如果我在相同的文件代码中使用PHP工作正常但页面需要重新加载：

$queryAPTChallenge = mysqli_query($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'];

echo "<table style='margin-top:50px;margin-left:65px;border-collapse:collapse;display:inline-block;'>

AJAX：

$(document).ready(
    $('body').on('click' , '#submitj1', function() {

    var id = $('input#idmeci').val();

    $.ajax({
        url: "submit.php",
        type: "POST",
        cache: false,
        data: {
            idd: id
        },
        succes: function(){
            alert('succes');
        }
    })

    });
});

submit.php：

$server = mysqli_connect("localhost", "root", "root");
$db = mysqli_select_db($server, "tenisapt");

$idmeci = $_POST['idd'];

$sql = "SELECT Set1j1,Set1j2,Set2j1,Set2j2,Set3j1,Set3j2 FROM meciurilive WHERE id=$idmeci";
$result = mysqli_query($server, $sql);

$row = mysqli_fetch_assoc($result);
$set1j1 = $row['Set1j1'];
$set1j2 = $row['Set1j2'];
$set2j1 = $row['Set2j1'];
$set2j2 = $row['Set2j2'];
$set3j1 = $row['Set3j1'];
$set3j2 = $row['Set3j2'];

if ((($set1j1<6) && ($set1j2<5)) || (($set1j1<5) && ($set1j2<6)) || (($set1j1==5) && ($set1j2==5)) || (($set1j1==6) && ($set1j2==5)) || (($set1j1==5) && ($set1j2==6)) || (($set1j1==6) && ($set1j2==6))){
    $actualizare = "UPDATE meciurilive SET Set1j1 = Set1j1 + 1 WHERE id=$idmeci";
    mysqli_query($server, $actualizare);
}
else if ((($set2j1<6) && ($set2j2<5)) || (($set2j1<5) && ($set2j2<6)) || (($set2j1==5) && ($set2j2==5)) || (($set2j1==6) && ($set2j2==5)) || (($set2j1==5) && ($set2j2==6)) || (($set2j1==6) && ($set2j2==6))){
    $actualizare = "UPDATE meciurilive SET Set2j1 = Set2j1 + 1 WHERE id=$idmeci";
    mysqli_query($server, $actualizare);
}
else if ((($set3j1<6) && ($set3j2<5)) || (($set3j1<5) && ($set3j2<6)) || (($set3j1==5) && ($set3j2==5)) || (($set3j1==6) && ($set3j2==5)) || (($set3j1==5) && ($set3j2==6)) || (($set3j1==6) && ($set3j2==6))){
    $actualizare = "UPDATE meciurilive SET Set3j1 = Set3j1 + 1 WHERE id=$idmeci";
    mysqli_query($server, $actualizare);
}

Answer 1

替换：

var id = $('input#idmeci').val();

with：

var id = $(this).prev('input').val();

ajax没有得到唯一的ID
