如何使用 Jquery 执行拖放操作？

Question

我想拖放。我从这个 Jquery Link.

得到了灵感

如果我应用相同的代码而不做任何更改，我的代码也能正常工作。现在我想更改UI 标签 的ID 名称。一旦我改变了，拖放就不起作用了。

这是我的代码

Aspx代码

$(function() {
  $("#ColumnNamesSortable, #sortable2").sortable({
    connectWith: ".connectedSortable"
  }).disableSelection();
});

#ColumnNamesSortable,
#sortable2 {
  border: 1px solid #846868;
  min-height: 20px;
  list-style-type: none;
  margin: 0;
  padding: 5px 0 0 0;
  float: left;
  margin-right: 10px;
}

#ColumnNamesSortable li,
#sortable2 li {
  margin: 0 5px 5px 5px;
  padding: 5px!important;
  font-size: 0.9em;
  width: 155px;
}

<link href="https://ajax.googleapis.com/ajax/libs/jqueryui/1.12.1/themes/smoothness/jquery-ui.css" rel="stylesheet" />

<ul id="ColumnNamesSortable" class="connectedSortable"> //change id name from sortable1 to ColumnNamesSortable (not working)
  <li class="ui-state-default">StoreID</li>
  <li class="ui-state-default">ItemLookupCode</li>
  <li class="ui-state-default">ExtendedDescription</li>
  <li class="ui-state-default">SubDescription1</li>
  <li class="ui-state-default">Department</li>
  <li class="ui-state-default">Category</li>
  <li class="ui-state-default">SupplierCode</li>
  <li class="ui-state-default">SupplierName</li>
  <li class="ui-state-default">TotalQuantity</li>
  <li class="ui-state-default">ExtendedPrice</li>
  <li class="ui-state-default">ExtendedCost</li>
  <li class="ui-state-default">Profit</li>
  <li class="ui-state-default">UnitOfMeasure</li>
  <li class="ui-state-default">CustomerAccountNumber</li>
  <li class="ui-state-default">CustomerName</li>
</ul>
<br />
<ul id="sortable2" class="connectedSortable"> // this one is working
  <li class="ui-state-highlight">Item 1</li>
  <li class="ui-state-highlight">Item 2</li>
  <li class="ui-state-highlight">Item 3</li>
  <li class="ui-state-highlight">Item 4</li>
  <li class="ui-state-highlight">Item 5</li>
</ul>

我想创建四个拖放。例如

ColumnNamesSortable
DataField
ColumnField
RowField

为什么当我更改特定标签的 ID 名称时它不起作用。而且它在控制台上没有显示任何错误。

这是一个工作示例。任何可排序的 li 都可以拖放到另一个。

只需将所有 ID 添加到选择器并实例化 sortable。

$("#ColumnNamesSortable, #sortable2, #ColumnField, #RowField").sortable({

工作示例：

$(function() {
  $("#ColumnNamesSortable, #sortable2, #ColumnField, #RowField").sortable({
    connectWith: ".connectedSortable"
  }).disableSelection();
});

li {
  list-style: none;
  padding: 2px 5px;
  margin-bottom: 8px;
  cursor: pointer;
}
