javascript - 尝试将可排序元素设置为禁用

Question

我使用 jQuery Sortable 对列表项进行排序。但是，我已将某些 li 元素设置为禁用类名，以禁用该特定项目的排序。我还将该类添加到 jquery 代码中以禁用，但它仍然允许重新排列这些项目

我查看了各种来源，这些来源说只需在选择器上使用启用/禁用，但似乎没有用我搜索过 SO 也看过这里 http://api.jqueryui.com/sortable/#method-option

 <script>
 $( function() {
 $( "#sortable" ).sortable();
 $( "#sortable" ).disableSelection();
 $(".notsortable").sortable("disable");
 } );
 </script>
 <ul id="sortable">
 <li class="ui-state-default notsortable">
  <span class="ui-icon ui-icon-arrowthick-2-n-s"></span>Order #1</li>
 <li class="ui-state-default">
 <span class="ui-icon ui-icon-arrowthick-2-n-s"></span>Order #2</li>
 <li class="ui-state-default">
   <span class="ui-icon ui-icon-arrowthick-2-n-s"></span>Order #3</li>
  <li class="ui-state-default">
    <span class="ui-icon ui-icon-arrowthick-2-n-s"></span>Order #4</li>
  <li class="ui-state-default">
   <span class="ui-icon ui-icon-arrowthick-2-n-s"></span>Order #5</li>
   <li class="ui-state-default">
    <span class="ui-icon ui-icon-arrowthick-2-n-s"></span>Order #6</li>
    <li class="ui-state-default">
    <span class="ui-icon ui-icon-arrowthick-2-n-s"></span>Order #7</li>
     </ul>

不应允许移动列表项，但事实并非如此

尝试这样做:

$(function() {
  $("#sortable").sortable({
    cancel: ".ui-state-disabled",
    items: "li:not(.ui-state-disabled)"
  })
});

.ui-state-disabled {
  opacity: 1 !important;
  pointer-events: auto !important;
}
