我正在尝试通过ajax在可排序更新上重新排序列表，但是在可排序已经在页面加载时初始化后通过ajax将新项目添加到此列表后，它无法识别带有“序列化”的新项目“功能。它确实允许我拖动它，就好像它正在工作一样，但是通过我的更新函数发送的代码缺少新元素。
//Sort categories
$('#categories-list').find('tbody').sortable({
connectWith: 'tbody',
opacity: 0.6,
cursor: 'move',
forcePlaceholderSize: true,
update: function(e) {
var serialized = $('#categories-list tbody').sortable('serialize');
console.log(serialized);
$.post('admin/ereg_forms/set_category_position', serialized, function(data) {
if (data.status == 'error') {
alert(data.message);
}
});
}
});
//Add category submit
$("#add-category-submit").click(function(e) {
e.preventDefault();
$(".errors-block").html('');
$('#add-category-submit').hide();
$.ajax({
url: $("#add-category-form").attr('action'),
type: 'POST',
data: $('#add-category-form').serialize(),
dataType: 'json',
success: function(data) {
$('#add-category-submit').show();
//Check if server side validation passed
if (data.status == 'error') {
//Show error on popup dialog
$("#add-category-form .errors-block").html(data.message);
alert('Sorry, the information that was sent is invalid. Please review the errors at the top of the form and try again.');
} else {
var category_data = data.data;
var tableRow = '<tr class="category-row-' + category_data.id + '"><td><span class="double-arrow-unicode" style="font-size:18px; cursor:pointer;">↕</span>' +
'</td><td>' + category_data.title +
'</td><td></tr>'
$(tableRow).appendTo('#categories-list tbody');
resetForm($('#add-category-form'));
//Close popup window
$('#add-category').dialog('close');
$("<div title='Success!'>Category has been saved.</div>").dialog({
modal: true,
width: 'auto'
});
}
},
error: function(data) {
alert('An unknown error has occurred, please try again.');
$('#add-category-submit').show();
}
});

<tbody>
<tr id="category-row-19">

<td class="category-row-title">test1</td>

<tr id="category-row-20">
<td><span class="double-arrow-unicode" style="font-size:18px; cursor:pointer;">↕</span></td>
<td class="category-row-title">test</td>
</tr>
</tbody>
</table>我到处寻找解决方案，但没有找到有效的解决方案。我尝试过将“刷新”功能与可排序一起使用，我尝试在ajax调用的成功函数内初始化可排序以添加新类别，但它也不起作用。
当我 console.log(serialized) 时，它只有数组中最初加载的元素。
最佳答案
不知道发生了什么，但是这个假添加有效，也许你可以模仿这个？请注意，我解决了一些语法问题，并使用 ajax Promise 方法来更好地组织它。
我建议您更新 jQuery 版本，在最新版本中提供一些更好的内容并修复错误。
