我正在使用AJAX删除PHP中的行，但显示行无法删除。 我的删除按钮就是这样...
while ($row = mysqli_fetch_array($exec))
{
?>
<tr>
<td><?php echo $row["create_date"]; ?></td>
<td><?php echo $row["bni_member_id"]; ?></td>
<td><?php echo $row["bni_member_name"]; ?></td>
<td><?php echo $row["bni_chapter_id"]; ?></td>
<td><?php echo $row["bni_category_id"]; ?></td>
<td><input type="button" name="delete" onclick="delFun()" value="delete" id="<?php echo $row["bni_member_id"]; ?>" class="btn btn-info btn-xs delete_data"/></td>
</tr>
<?php
}
?>
我在点击按钮上调用了一个函数。像这样的功能。 它总是执行部分不能删除。我认为
有问题data: {del_id: del_id},
我认为数据有问题...但是我无法解决。
var delfin;
$(document).ready(function () {
delFun = function () {
$('.delete_data').click(function () {
var del_id = $(this).attr("name");
var $ele = $(this).parent().parent();
$.ajax({
url: "phpfile/delete.php",
method: "POST",
data: {del_id: del_id},
success: function (data) {
if(data=="YES"){
$ele.fadeOut().remove();
}else{
alert("can't delete the row")
}
}
});
});
}
});
我的PHP文件在这样的另一个目录中
<?php
include('../../connection.php');
$music_number = $_POST['del_id'];
//echo $music_number;
$qry = "DELETE FROM bni_member WHERE bni_member_id ='$music_number'";
$result=mysql_query($qry);
if(isset($result)) {
echo "YES";
} else {
echo "NO";
}
?>
我的桌子就像

`bni_member_id` int(11) NOT NULL AUTO_INCREMENT,
`bni_member_name` text,

第一个问题是，您从“删除”按钮获得了name属性。您可以将bni_member_id作为数据属性来传递，而不是使用元素id属性。可能引起混乱。第二个问题是，您同时使用了onlick属性和jQuery的click方法。使用一个就足够了。您的输入按钮将如下所示：
<td><input type="button" name="delete" value="delete" class="btn btn-info btn-xs delete_data" data-bni-member-id="<?= $row["bni_member_id"]; ?>" /></td>
然后您的js将如下所示：
$(document).ready(function () {
$('.delete_data').click(function () {
var del_id = $(this).data("bni_member_id");
var $ele = $(this).parent().parent();
$.ajax({
url: "phpfile/delete.php",
method: "POST",
data: {del_id: del_id},
success: function (data) {
if(data=="YES"){
$ele.fadeOut().remove();
} else {
alert("can't delete the row")
}
}
});
});
});
希望对您有帮助。

您可以更改删除按钮
<input type="button" name="delete" onclick="delFun()" value="delete" data-id="<?php echo $row["bni_member_id"]; ?>" class="btn btn-info btn-xs delete_data"/>
和Jquery事件
$(document).on("click",".delete_data",function () {
var del_id = $(this).data("id");
