这是我的brand.php文件 它刻画了品牌的编辑部分 所以在这一部分中，我们可能会看到事情的样子
<!-- edit brand -->

这是获取部分，其中一旦单击行（示例行1）中的按钮，就会出现模态（可能会出现“编辑模态”），但事实是，一旦模态出现，假定的数据从行中获取不是在该模式上;-;
<?php
require_once '../../includes/connection.php';
$brandId = $_POST['brandId'];
$sql = "SELECT brand_id, brand_name, brand_active, brand_status FROM brands WHERE brand_id = $brandId";
$result = $connect->query($sql);
if($result->num_rows > 0) {
$row = $result->fetch_array();
} // if num_rows
$connect->close();
echo json_encode($row);
?>
现在是JScript部分 这一部分是填充部分（例如获取数据，现在刻画数据并填充输入框等。）
function editBrands(brandId = null) {
if(brandId) {
// remove hidden brand id text
$('#brandId').remove();
// remove the error
$('.text-danger').remove();
// remove the form-error
$('.form-group').removeClass('has-error').removeClass('has-success');
// modal loading
$('.modal-loading').removeClass('div-hide');
// modal result
$('.edit-brand-result').addClass('div-hide');
// modal footer
$('.editBrandFooter').addClass('div-hide');
$.ajax({

可以检查“网络”选项卡以查看服务器的结果吗？您可以通过查看结果来调试应用。
顺便说一句，您可能需要编辑两件事：
1 /如果brandId是整数，则需要通过intval($_POST['brandId'])从$ _GET获取它，以防止SQL注入。
2 /
if($result->num_rows > 0) {
$row = $result->fetch_array();
}
else {
$row = array();
}
如果sql结果为空，您的代码需要返回空数组，以避免Undefined variable错误。
