jQWidgets jqxGrid handlekeyboardnavigation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。

每当按下键盘上的某个键时，就会调用handlekeyboardnavigation 属性。此外，如果此处的输出为 true，则按下的键将覆盖键盘的默认导航。它是 function 类型，默认值为 null。

用法:

设置handlekeyboardnavigation属性：

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

返回handlekeyboardnavigation属性：

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