Javascript 尝试使用按钮和主键从数据库中查找数据时，未找到ajax get 404

所以我想使用按钮和主键从数据库中获取数据，如下所示：

while($row = mysqli_fetch_array($query))
{
    echo "<tr class = 'raw' id = 'data'>";
    echo "  <td><button onclick = 'gettahun(".$row['kdTahun'].")' data-dismiss='modal'>#</button></td>";
    echo "  <td class = 'kdTAHUN'>".$row['kdTahun']."</td>";
    echo "  <td class = 'TAHUN'>".$row['tahun']."</td>";
    echo "</tr>";
}

我的php用于prosses输入并将数据发送到textbox是：

<?php
session_start();
$host = "localhost";
$user = "root";
$pass = "";
$name = "buku_tahunan";

$koneksi = mysqli_connect($host,$user,$pass,$name);

if(mysqli_connect_errno())
{
    die("koneksi DB Gagal".mysqli_connect_error());
}
$kdfakultas = $_GET["kdFakultas"];

$sql="SELECT * FROM `fakultas` WHERE kdFakultas = '$kdfakultas'";

$query = mysqli_query($koneksi,$sql);

while($row = mysqli_fetch_array($query))
{
    $output =  array('KDFAKULTAS'=>$row['kdFakultas'],
             'FAKULTAS'=>$row['nmFakultas']);
    echo json_encode($output);
}
 ?>

routes

文件夹中是否有

getfakulas.php

文件？是的，getfakulas.php文件在routes文件夹中。如果您直接在浏览器中访问链接，您没有

404

？当我试图访问直接指向我的浏览器的链接时出现错误404。您是否在laravel中尝试此操作。？

<?php
session_start();
$host = "localhost";
$user = "root";
$pass = "";
$name = "buku_tahunan";

$koneksi = mysqli_connect($host,$user,$pass,$name);

if(mysqli_connect_errno())
{
    die("koneksi DB Gagal".mysqli_connect_error());
}
$kdfakultas = $_GET["kdFakultas"];

$sql="SELECT * FROM `fakultas` WHERE kdFakultas = '$kdfakultas'";

$query = mysqli_query($koneksi,$sql);

while($row = mysqli_fetch_array($query))
{
    $output =  array('KDFAKULTAS'=>$row['kdFakultas'],
             'FAKULTAS'=>$row['nmFakultas']);
    echo json_encode($output);
}
 ?>
