我已经创建了ajax代码，以使用引导程序模式版本3.3.7（参考<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css">）显示详细信息，并且工作正常。
但是当我想使用Bootstrap 4来实现它时，我遇到了一个问题，当单击“进程”时，没有响应并且模态没有出现。
<div class="container">
<h2> Proses Penerimaan Siswa Baru </h2>
<table id="tablee" class="display nowrap" cellspacing="0" width="100%">
<thead>
<tr>
<th> ID PSB </th>
<th> Nama </th>
<th> Sekolah Asal </th>
<th> Kelas </th>
<th> Tahun Pelajaran </th>
<th> Action </th>
</tr>
</thead>
<tbody>
<?php
$sql="SELECT * FROM psbsmp";
$resultset=mysqli_query($connection,$sql) or die(mysqli_error());
while ($rows=mysqli_fetch_array($resultset)){
?>
<tr id="<?php echo $rows['id']; ?>">
<td data-target="idpsb"><?php echo $rows["idpsb"]; ?></td>
<td data-target="nama"><?php echo $rows["nama"]; ?></td>
<td> <?php echo $rows["sekolahasal"]; ?></td>
<td> <?php echo $rows["kelas"]; ?></td>
<td> <?php echo $rows["tahunmasuk"]; ?></td>
<td><a href="#" data-role="update" data-id="<?php echo $rows['id'] ;?>">Process</a></td>
</tr>
<?php
}
?>
</tbody>
</table>
这是模态代码：

Ajax代码
$(document).ready(function(){
// append values in input fields
$(document).on('click','a[data-role=update]',function(){
var id = $(this).data('id');
var idpsb = $('#'+id).children('td[data-target=idpsb]').text();
var nama = $('#'+id).children('td[data-target=nama]').text();
$('#idpsb').val(idpsb);
$('#nama').val(nama);
$('#userId').val(id);
$('#myModal').modal('toggle');
});
// now create event to get data from fields and update in database
$('#save').click(function(){
var id = $('#userId').val();
var idpsb = $('#idpsb').val();
var nama = $('#nama').val();
$.ajax({
url : 'connection.php',
method : 'post',
data : {idpsb : idpsb , nama : nama , id : id},
success : function(response){
// now update user record in table
$('#'+id).children('td[data-target=idpsb]').text(idpsb);
$('#'+id).children('td[data-target=nama]').text(nama);
$('#myModal').modal('toggle');
}
});
});
});
它与我使用的<a></a>元素的按钮功能有关吗？

这里是工作模态的简单示例，请检查应用程序中的bootstrap 4链接以及模态的html内容

use css to display modal in your javascript
$.ajax({
url : 'connection.php',
method : 'post',
data : {idpsb : idpsb , nama : nama , id : id},
success : function(response){
// now update user record in table
$('#'+id).children('td[data-target=idpsb]').text(idpsb);
$('#'+id).children('td[data-target=nama]').text(nama);
$('#myModal').css('display','block');
}
});
