jQWidgets jqxDataTable sortBy()用法及代码示例

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、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。它还用于显示来自各种数据源(例如 XML、JSON、Array、CSV 或 TSV)的数据。

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

用法:

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

Parameters: 该方法接受两个参数，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。其值为‘asc’(升序)、‘desc’(降序)或 null。
