【问题描述】：

我有一张可以通过图标排序的表格

图标按升序和降序排列

下面的代码是通过inspect elements得到的

<th id="thCliente" class="sorting_desc" tabindex="0" aria-controls="basic-datatable" rowspan="1" colspan="1" style="width: 336.984px;" aria-sort="descending" aria-label="Cliente: Ordenar colunas de forma ascendente">Cliente</th>

我需要在加载页面时总是在 sort_asc - 升序排序

如何使用 javascript 和/或 jquery 执行此操作？

订购图标的图像

出现在检查元素中的代码

尝试

$("#thCliente").removeClass().addClass("sorting_asc:before")

表格代码：

<div class="col-sm-12">
   <div class="dataTables_scroll">
      <div class="dataTables_scrollHead" style="overflow: hidden; position: relative; border: 0px; width: 100%;">
         <div class="dataTables_scrollHeadInner" style="box-sizing: content-box; width: 1119px; padding-right: 0px;">
            <table class="table table-sm font-size-12 table-striped nowrap dataTable no-footer" role="grid" style="margin-left: 0px; width: 1119px;">
               <thead>

【问题讨论】：

我敢打赌，改变班级实际上不会对表格进行排序。你是如何创建表格的？
该表具有预设的模板定义，但我使用 Classic ASP 将数据库中的数据提供给它
如有需要，我可以贡献代码和图片。
其中一个预设模板定义几乎可以肯定是排序顺序。
我明白，但我在系统的几个区域使用同一个表，这种情况特别是通过具有特定值的选择和访问页面时排序

标签： javascript html jquery

【解决方案1】：

根据有限的信息，我在这里猜测了一半。但在大多数情况下，该类实际上并不控制排序顺序（通常是相反的）。

在绝大多数情况下，控制排序顺序的元素上会有一个点击事件，所以你可以做什么（如果没有可以在创建表格时直接设置的属性）是什么像这样：

$('#thCliente').click();

假设该元素确实是控制排序顺序的元素。

虽然为了澄清你对如何切换班级的误解：

$('#thCliente').toggleClass('sorting_asc sorting_desc');

将切换升序和降序类。但它不会切换任何相应的aria 属性。
