jquery - 使用 JQuery 对包含 HTML 内容的 HTML 列表进行排序

Question

是否可以将下面的列表从较小的数字到较大的数字进行排序，同时保留每个 li 内容？

<ul>
    <li>
        39
        <img class="botao-remover-tamanho" title="Remover cor" alt="" src="/admin/imagens/botao-excluir-cor.png">
        <input type="hidden" title="39" value="39" name="array_variacao[]">
    </li>
    <li>
        34
        <img class="botao-remover-tamanho" title="Remover cor" alt="" src="/admin/imagens/botao-excluir-cor.png">
        <input type="hidden" title="34" value="34" name="array_variacao[]">
    </li>
    <li>
        38
        <img class="botao-remover-tamanho" title="Remover cor" alt="" src="/admin/imagens/botao-excluir-cor.png">
        <input type="hidden" title="38" value="38" name="array_variacao[]">
    </li>
    <li>
        35
        <img class="botao-remover-tamanho" title="Remover cor" alt="" src="/admin/imagens/botao-excluir-cor.png">
        <input type="hidden" title="35" value="35" name="array_variacao[]">
    </li>
    <li>
        33
        <img class="botao-remover-tamanho" title="Remover cor" alt="" src="/admin/imagens/botao-excluir-cor.png">
        <input type="hidden" title="33" value="33" name="array_variacao[]">
    </li>
</ul>

我需要像下面这样自动排序，因为列表将是动态创建的。

<ul>
    <li>
        33
        <img class="botao-remover-tamanho" title="Remover cor" alt="" src="/admin/imagens/botao-excluir-cor.png">
        <input type="hidden" title="33" value="33" name="array_variacao[]">
    </li>
    <li>
        34
        <img class="botao-remover-tamanho" title="Remover cor" alt="" src="/admin/imagens/botao-excluir-cor.png">
        <input type="hidden" title="34" value="34" name="array_variacao[]">
    </li>
    <li>
        35
        <img class="botao-remover-tamanho" title="Remover cor" alt="" src="/admin/imagens/botao-excluir-cor.png">
        <input type="hidden" title="35" value="35" name="array_variacao[]">
    </li>
    <li>
        38
        <img class="botao-remover-tamanho" title="Remover cor" alt="" src="/admin/imagens/botao-excluir-cor.png">
        <input type="hidden" title="38" value="38" name="array_variacao[]">
    </li>
    <li>
        39
        <img class="botao-remover-tamanho" title="Remover cor" alt="" src="/admin/imagens/botao-excluir-cor.png">
        <input type="hidden" title="39" value="39" name="array_variacao[]">
    </li>
</ul>

感谢您的帮助!

编辑:

根据评论中@Blender的建议，我使用了下面帖子中的代码，它对我来说效果很好。

What is the easiest way to order a <UL>/<OL> in jQuery?

Answer 1

尝试下面的代码，

$(function() {
    $('button').click(function() {
        var liContents = [];
        $('ul li').each(function() {
            liContents.push($(this).html());
        });
        liContents.sort(liSorter);
        $('ul li').each(function() {
            $(this).html(liContents.pop());
        });
    });
});

/*
  Below function is kind of a workaround for the listed HTMl
  you need to update it if you have proper HTML.
*/
function liSorter(a, b) {
    return (parseInt(b) - parseInt(a));
}

编辑:更新了您的标记以获得更好的代码，

1. 用 span 包裹这些号码标签如 <span class="num">39</span>
2. 更新了排序器功能如下，

代码:

function numOrdDesc(a, b) {
    var aTxt = parseInt($(a).find('.num').text(), 10);
    var bTxt = parseInt($(b).find('.num').text(), 10);
    return (bTxt - aTxt);
}
