按 Javascript 排序 HTML table

Question

我有以下 HTML table 我想按 data-sku=""

排序

( function() {
        $("table tbody tr").sort(sort_table).appendTo('table tbody');
            function sort_table(a, b) {
            return ($(b).data('sku')) < ($(a).data('sku')) ? 1 : -1;
        }
} )();

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<table>
<tbody>
<tr class="abp-product-42" data-id="42" data-sku="A-04-0002"><td>A-04-0002</tr>
<tr class="abp-product-21" data-id="21" data-sku="A-04-0011"><td>A-04-0011</td></tr>
<tr class="abp-product-391" data-id="391" data-sku="A-02-0008"><td>A-02-0008</td></tr>
<tr class="abp-product-393" data-id="393" data-sku="A-02-0007"><td>A-02-0007</td></tr>
<tr class="abp-product-40" data-id="40" data-sku="A-04-0010"><td>A-03-0010</td></tr>
<tr class="abp-product-390" data-id="390" data-sku="A-03-0003"><td>A-04-0003</td></tr>
</tbody>
</table>

但不知何故它不起作用 - 我做错了什么或我错过了什么？

Answer 1

您的代码运行良好。
只是，最后 2 行属性 data-sku 与其单元格内容不匹配。

<tr class="abp-product-40" data-id="40" data-sku="A-04-0010">
    <td>A-03-0010</td>
</tr>
<tr class="abp-product-390" data-id="390" data-sku="A-03-0003">
    <td>A-04-0003</td>
</tr>

(function () {
    function sort_table(a, b) {
        return ($(b).attr('data-sku')) < ($(a).attr('data-sku')) ? 1 : -1;
    }
    $("table tbody tr").sort(sort_table).appendTo('table tbody');
})();

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<table>
    <tbody>
        <tr class="abp-product-42" data-id="42" data-sku="A-04-0002">
            <td>A-04-0002
        </tr>
        <tr class="abp-product-21" data-id="21" data-sku="A-04-0011">
            <td>A-04-0011</td>
        </tr>
        <tr class="abp-product-391" data-id="391" data-sku="A-02-0008">
            <td>A-02-0008</td>
        </tr>
        <tr class="abp-product-393" data-id="393" data-sku="A-02-0007">
            <td>A-02-0007</td>
        </tr>
        <tr class="abp-product-40" data-id="40" data-sku="A-03-0010">
            <td>A-03-0010</td>
        </tr>
        <tr class="abp-product-390" data-id="390" data-sku="A-04-0003">
            <td>A-04-0003</td>
        </tr>
    </tbody>
</table>

Answer 2

这将像我在评论中提到的那样每 5 秒调用一次您的函数。

window.setInterval(function(){
 sortData();
}, 5000);

function sortData(){
 $("table tbody tr").sort(sort_table).appendTo('table tbody');
            function sort_table(a, b) {
            return ($(b).data('sku')) < ($(a).data('sku')) ? 1 : -1;
        }
}

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<table>
<tbody>
<tr class="abp-product-42" data-id="42" data-sku="A-04-0002"><td>A-04-0002</tr>
<tr class="abp-product-21" data-id="21" data-sku="A-04-0011"><td>A-04-0011</td></tr>
<tr class="abp-product-391" data-id="391" data-sku="A-02-0008"><td>A-02-0008</td></tr>
<tr class="abp-product-393" data-id="393" data-sku="A-02-0007"><td>A-02-0007</td></tr>
<tr class="abp-product-40" data-id="40" data-sku="A-04-0010"><td>A-04-0010</td></tr>
<tr class="abp-product-390" data-id="390" data-sku="A-03-0003"><td>A-03-0003</td></tr>
<tr class="abp-product-390" data-id="390" data-sku="A-05-0003"><td>A-05-0003</td></tr>
</tbody>
</table>
