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。
virtualmode 属性用于激活或停用显示的 jqxGrid 的虚拟模式。布尔类型，默认值为“false”。
用法:
- 设置 虚拟模式属性：
$('Selector').jqxGrid({ virtualmode: true });
- 返回虚拟模式属性：
var virtualmode = $('Selector').jqxGrid('virtualmode');
