jQWidgets jqxDataTable sortBy() 方法

jQWidgets是一个 JavaScript 框架，用于为 PC 和移动设备制作基于 Web 的应用程序。它是一个非常强大、经过优化、独立于平台且得到广泛支持的框架。 jqxDataTable用于读取和显示 HTML 表中的数据。这也用于显示来自各种数据源（如 XML、JSON、Array、CSV 或 TSV）的数据。

如果 sortable 设置为 true，则sortBy()方法用于对指定的列进行排序。

句法：

$("#dataTable").jqxDataTable('sortBy', 'dataField', 'sortOrder');

参数：此方法接受两个参数，如下所示：

• dataField：这是指定的列名，将根据该列名执行排序。
• sortOrder：这是排序顺序字符串。它的值为'asc'（升序）、'desc'（降序）或null。

链接文件：从给定链接下载 jQWidgets。在 HTML 文件中，找到下载文件夹中的脚本文件。
