jQWidgets jqxGrid getselectedcells()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。 jqxGrid 用于演示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。

getselectedcells() 方法用于从显示的 jqxGrid 返回每个选定的单元格。其中，选择方式为单单元、多单元、或多单元扩展。它没有参数。

用法:

var cells = $('#Selector').jqxGrid('getselectedcells');

返回类型：它返回每个选定单元格的数组。然而，每个单元格都是一个对象，它有两个字段，即行索引(行的绑定索引)和数据字段(列的数据字段)。
