大家好只想在我的桌面显示上询问你的帮助，按下表格行上的删除图标后，我按下要删除的行仍在那里虽然在数据库上它已被删除。页面没有刷新。
这是我的表格身份
<div id="display" align="left"></div>
这是ajax脚本
<script type="text/javascript">
function deletedata(str){
var med_id = str;
$.ajax({
type: "GET",
url: "deletedata.php?med_id="+med_id,
}).done(function( data ) {
});
}
</script>
这是我的demo_insert.php
<?php
$dbHost = 'localhost'; // usually localhost
$dbUsername = 'root';
$dbPassword = 'thartpc';
$dbDatabase = 'hospital';
$db = mysql_connect($dbHost, $dbUsername, $dbPassword) or die ("Unable to connect to Database Server.");
mysql_select_db ($dbDatabase, $db) or die ("Could not select database.");
$sql_check = mysql_query("SELECT * FROM messages order by med_id desc");
if(isSet($_POST['content2']))
{
$content2=$_POST['content2'];
$content3=$_POST['content3'];
$content4=$_POST['content4'];
mysql_query("insert into messages(medname, quantity, patientid) values ('$content2','$content3','$content4')");
$sql_in= mysql_query("SELECT * FROM messages order by med_id desc");
$r=mysql_fetch_array($sql_in);
}
?>
<?php
require_once 'config.php';
$query = mysql_query("SELECT * FROM messages where patientid = '$content4'order by med_id desc") or die ("could not search");
$count = mysql_num_rows($query);
?>
<div class="panel panel-info">
<div class="panel-heading"><class="panel-title"><h7>Transaction</h7></div>
<div class="panel-body" style="padding-top:30px">

while($row = mysql_fetch_array($query))
{

</tr>
<?php
}
echo "</table>";
?>
</div>
</div>
这是我的表删除查询
<?php
include "getconnect.php";
if(isset($_GET['med_id'])){
$stmt = $conn->prepare("delete from messages where med_id=?");
$stmt->bind_param('s', $med_id);
$med_id = $_GET['med_id'];
$stmt->execute();

如果您的页面没有重新加载，那么您可以手动删除它。
例如，您认为您的行ID（或其他内容）是“row123”。
您需要更改代码，如下所示
<script type="text/javascript">
function deletedata(str){
var med_id = str;
$.ajax({
type: "GET",
url: "deletedata.php?med_id="+med_id,
}).done(function( data ) {
//add this code
$("#row123").remove();
});
}
</script>

为该行添加Id属性与$ row [＆＃39; med_id＆＃39;]相同。我已经向行添加了数据属性（数据删除），以便我们知道要删除哪个ID。 您需要从我已经说明的代码中添加一个类到按钮 你需要做什么。
<?php
while ($row = mysql_fetch_array($query)) {
echo "
<tr>
<td id='" . $row['med_id'] . "' style='border:1px solid; color:gray' align='center'>" . $row['med_id'] . "</td>
<td style='border:1px solid; color:gray' align='center'>" . $row['patientid'] . "</td>
<td style='border:1px solid; color:gray' align='center'>" . $row['medname'] . "</td>
<td style='border:1px solid; color:gray' align='center'>" . $row['quantity'] . "</td>
<td style='border:1px solid; color:gray' align='center'>" . $row['quantity'] . "</td>
<td style='border:1px solid; color:gray' align='center'>" . $row['quantity'] . "</td>
"
?>
<td style='border:1px solid; color:gray' align='center'>
<a class="delete-button btn btn-danger btn-sm" data-delete="<?php echo $row['med_id']; ?>">
<span class="glyphicon glyphicon-trash" aria-hidden="true"></span>
</a>
</td>
</tr>
<?php } ?>
在您的脚本上执行以下操作
<script type="text/javascript">
//listen to a click even for the button
$(document).ready(function () {
$('.delete-button').click(function () {
//this will be the id for the data to be deleted on the database
var med_id = $(this).data('delete');
$.ajax({
type: "GET",
cache: false,
dataType: "json",
url: "deletedata.php?med_id=" + med_id,
success: function (deletedID) {
$("tr#" + deletedID).remove();
}, error: function (xhr, ajaxOptions, thrownError) {
alert("an error occured. delete was not successful :( ");
}
});
});
});
</script>
将此添加到您的删除查询中以返回json有效数据，该数据将是已删除行的ID。
<?php
include "getconnect.php";
if (isset($_GET['med_id'])) {
$med_id = $_GET['med_id'];
$stmt = $conn->prepare("delete from messages where med_id=?");
$stmt->bind_param('s', $med_id);
$stmt->execute();
echo json_encode($med_id);
die();
}
?>

完成处理后，只需添加即可。尝试将其放入已完成的功能
location.reload();
