Question

试图使元素可排序，但仅适用于一个以上的容器。在jsFiddle中，您将看到第一个Container有效，但第二个不起作用？

$("#sortable").sortable({
    cancel: ".fixed"
});
$("#sortable").disableSelection();

HTML：

<div class="demo">
<ul id="sortable">
    <li class="ui-state-default"><span class="ui-icon ui-icon-arrowthick-2-n-s"></span>Item 1</li>
    <li class="ui-state-default"><span class="ui-icon ui-icon-arrowthick-2-n-s"></span>Item 2</li>
    <li class="ui-state-default fixed"><span class="ui-icon ui-icon-arrowthick-2-n-s"></span>Item 3</li>
    <li class="ui-state-default"><span class="ui-icon ui-icon-arrowthick-2-n-s"></span>Item 4</li>
    <li class="ui-state-default fixed"><span class="ui-icon ui-icon-arrowthick-2-n-s"></span>Item 5</li>
    <li class="ui-state-default"><span class="ui-icon ui-icon-arrowthick-2-n-s"></span>Item 6</li>
    <li class="ui-state-default"><span class="ui-icon ui-icon-arrowthick-2-n-s"></span>Item 7</li>
</ul>
<hr/>
<ul id="sortable">
    <li class="ui-state-default"><span class="ui-icon ui-icon-arrowthick-2-n-s"></span>Item 1</li>
    <li class="ui-state-default"><span class="ui-icon ui-icon-arrowthick-2-n-s"></span>Item 2</li>
    <li class="ui-state-default fixed"><span class="ui-icon ui-icon-arrowthick-2-n-s"></span>Item 3</li>
    <li class="ui-state-default"><span class="ui-icon ui-icon-arrowthick-2-n-s"></span>Item 4</li>
    <li class="ui-state-default fixed"><span class="ui-icon ui-icon-arrowthick-2-n-s"></span>Item 5</li>
    <li class="ui-state-default"><span class="ui-icon ui-icon-arrowthick-2-n-s"></span>Item 6</li>
    <li class="ui-state-default"><span class="ui-icon ui-icon-arrowthick-2-n-s"></span>Item 7</li>
</ul>

CSS：

#sortable { list-style-type: none; margin: 0; padding: 0; width: 60%; }
#sortable li { margin: 0 3px 3px 3px; padding: 0.4em; padding-left: 1.5em; font-size: 1.4em; height: 18px; cursor:move; }
#sortable li span { position: absolute; margin-left: -1.3em; }
#sortable li.fixed{cursor:default; color:#959595; opacity:0.5;}

该如何解决？我对这些东西很陌生，无法解决这个问题。

谢谢！

Answer 1

拥有多个具有相同id的元素被认为是无效的，因为每个元素的id必须唯一。

如果您将id更改为课程：

class="sortable"

并更改您的jQuery以使用class选择器代替id选择器：

$(".sortable")

您的问题将得到解决，请参见下面的工作示例：

$(".sortable").sortable({
  cancel: ".fixed"
});
$(".sortable").disableSelection();

.sortable {
  list-style-type: none;
  margin: 0;
  padding: 0;
  width: 60%;
}

.sortable li {
  margin: 0 3px 3px 3px;
  padding: 0.4em;
  padding-left: 1.5em;
  font-size: 1.4em;
  height: 18px;
  cursor: move;
}

.sortable li span {
  position: absolute;
  margin-left: -1.3em;
}

.sortable li.fixed {
  cursor: default;
  color: #959595;
  opacity: 0.5;
}

    Enable a group of DOM elements to be sortable. Click on and drag an element to a new spot within the list, and the other items will adjust to fit. By default, sortable items share <code>draggable</code> properties.
