jQWidgets jqxGrid groupsrenderer属性用法及代码示例

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。这江青网格用于说明以表格形式显示数据的 jQuery 小部件。此外，它还全面支持数据连接、分页、分组、排序、过滤和编辑。

每当在显示的 jqxGrid 中返回一个组时，都会调用 groupsrenderer 属性。可以利用此属性来自定义默认组渲染。它是函数类型，默认值为null。

用法:

设置 groupsrenderer 属性：

$('Selector').jqxGrid({ groupsrenderer: null });

返回 groupsrenderer 属性：

var groupsrenderer = $('Selector').jqxGrid('groupsrenderer');
