javascript-尝试将可排序元素设置为禁用

我正在使用jQuery Sortable来排序列表项.但是,我为某些li元素设置了禁用类名称,以禁用对该特定项目的排序.
我还将该类添加到了jQuery代码中以禁用,但是它仍然允许重新排列这些项目

我看过各种消息来源,说只是在选择器上使用了启用/禁用,但是似乎无法工作
我搜索了SO,还看了这里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>

列表项不应被允许移动,但事实并非如此

解决方法:

尝试以这种方式：

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

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

  </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>
