上下移动UI Li中的物品 [英] Move items in Ul Li up and down

问题描述

我有一个UI li，点击向上和向下按钮，我想要移动li元素上下移动。
这是在页面上呈现的html。

I have a Ul li and on click of a Up and Down buttons I want to move to move the li elements up and down. Here is the html that is rendered on the page.

我已经尝试了链接中提到的解决方案但是它可以使用jQuery来轻松地转换li元素吗？

I already tried the solution mentioned in the link Can I use jQuery to easily shift li elements up or down? but it didn't work for me.

      <ul id="ul_li_SubCategories" style="width:200px;" class="chargeCapturetable margin0">
    <li sequence="1" title="Category 1" class="liEllipsis" value="9"><a href="#"><span class="viewIcons delFaceName _delete fl"></span>Category 1</a></li>
    <li sequence="2" title="Category 3" class="liEllipsis" value="11"><a href="#"><span class="viewIcons delFaceName _delete fl"></span>Category 3</a></li>
    <li sequence="4" title="Category 4" class="liEllipsis" value="12"><a href="#"><span class="viewIcons delFaceName _delete fl"></span>Category 4</a></li>
    <li sequence="5" title="Category 6" class="liEllipsis" value="22"><a href="#"><span class="viewIcons delFaceName _delete fl"></span>Category 6</a></li>
    <li sequence="6" title="Category 5" class="liEllipsis" value="13"><a href="#"><span class="viewIcons delFaceName _delete fl"></span>Category 5</a></li>
    <li sequence="7" title="Category 7" class="liEllipsis" value="55"><a href="#"><span class="viewIcons delFaceName _delete fl"></span>Category 7</a></li>
<li sequence="99999" title="Category 8" class="liEllipsis" value="62"><a href="#"><span class="viewIcons delFaceName _delete fl"></span>Category 8</a></li></ul>

推荐答案

您可以尝试如下所示：

$('.upbutton').on('click', function () {
    var hook = $(this).closest('.liEllipsis').prev('.liEllipsis');
    var elementToMove = $(this).closest('.liEllipsis').detach();
    hook.before(elementToMove);
});
$('.downbutton').on('click', function () {
    var hook = $(this).closest('.liEllipsis').next('.liEllipsis');
    var elementToMove = $(this).closest('.liEllipsis').detach();
    hook.after(elementToMove);
});

如果您想使用外部按钮和选定的li元素进行移动，请尝试这样的：（'click'，function（）{
$（'。liEllipsis'）。

If you want to move using a button outside, and a selected li element, try something like this:

$('.liEllipsis').on('click', function () {
    $('.selected').removeClass('selected');
    $(this).addClass('selected');
});

$('.upbutton').on('click', function () {
    var $currentElement = $('#ul_li_SubCategories .selected');
    moveUp($currentElement);
});

$('.downbutton').on('click', function () {
    var $currentElement = $('#ul_li_SubCategories .selected');
    moveDown($currentElement);
});

var moveUp = function ($currentElement) {
    var hook = $currentElement.prev('.liEllipsis');
    if (hook.length) {
        var elementToMove = $currentElement.detach();
        hook.before(elementToMove);
    }
};

var moveDown = function ($currentElement) {
    var hook = $currentElement.next('.liEllipsis');
    if (hook.length) {
        var elementToMove = $currentElement.detach();
        hook.after(elementToMove);
    }
};
