我有一个很大的列表，我试图让它可以排序。

我希望父项.cat-title可以在彼此之间进行排序，这将使子项与它们一起移动。但是我希望.cat-title's 的孩子可以在每个孩子之间进行排序.cat-title。

它像类别和子项目，但 jQuery 可排序只是没有做我期望的事情

您的选择器只是试图对所有 li 进行排序。Sortable 需要在每个单独的列表（特别是 ul 标签）上调用。这决定了可以拖动事物的边界。所以给每个列表一个 id 然后让它们都可以排序。（往下看）

<ul id="user-stream-list" class="user-stream-list">
<li class="feed ui-sortable "><span class="cat-title" data-title="5">Apple</span>
    <ul id="appleSub">
        <li class="feed sub"><a data-uid="15" data-fid="11" href="http://appleinsider.com/appleinsider.rss"><img src="https://www.google.com/s2/favicons?domain=appleinsider.com" class="favicon"><span class="title">AppleInsider</span><span class="options"><span data-fid="11" class="addcat">+</span><span class="delete">×</span></span></a></li>
        <li class="feed sub"><a data-uid="15" data-fid="29" href="http://9to5mac.com/feed/"><img src="https://www.google.com/s2/favicons?domain=9to5mac.com" class="favicon"><span class="title">9to5Mac</span><span class="options"><span data-fid="29" class="addcat">+</span><span class="delete">×</span></span></a></li>
    </ul>
</li>
<li class="feed ui-sortable"><span class="cat-title" data-title="15">Gadgets</span>
    <ul id="gadgetSub">
        <li class="feed sub"><a data-uid="15" data-fid="2" href="http://www.engadget.com/rss.xml"><img src="https://www.google.com/s2/favicons?domain=www.engadget.com" class="favicon"><span class="title">Engadget</span><span class="options"><span data-fid="2" class="addcat">+</span><span class="delete">×</span></span></a></li>

jQuery

$(function() {
    $( "#user-stream-list" ).sortable();
});
$(function() {
    $( "#appleSub" ).sortable();
});
$(function() {
    $( "#techSub" ).sortable();
});
$(function() {
    $( "#gadgetSub" ).sortable();
});
$(function() {
    $( "#uncatSub" ).sortable();
});

除了将 sortable 函数移动到<li>from 之外，<ul>我还必须将 stopPropagation 添加到 sortable 中的 dragstart 事件中。这允许无限嵌套的列表正常工作。

items.attr('draggable', 'true').on('dragstart.h5s', function(e) {
    e.stopPropagation(); // add this line to jquery.sortable.js
    .....
}

然后，当调用 sortable() 时，列表需要全部“连接”：

$('.sortable').sortable({ connectWith: '.sortable' });

根据我的经验，简单地移动到<ul>标签只会移动顶级列表项，即使点击了一个孩子。
