jQWidgets jqxGrid rowexpand 事件

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。 jqxGrid 用于说明以表格形式显示数据的 jQuery 小部件。此外，它完全支持连接数据，以及分页、分组、排序、过滤和编辑。

每当展开一行以及显示的 jqxGrid 的详细信息时，就会激活rowexpand 事件。

句法：

$("#Selector").on("rowexpand", function (event) {

   // Arguments of the event
   var args = event.args;
   
   // Bound index of the row
   var boundIndex = args.rowindex;
   
   // Details of the row
   var details = args.details;
});
