极客教程jQWidgets jqxDataTable cellBeginEdit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。它是一个非常强大的、优化的、与平台无关的、并被广泛支持的框架。jqxDataTable是用来读取和显示HTML表的数据的。这也用于显示来自各种数据源的数据，如XML，JSON，Array，CSV，或TSV。
每当用户开始编辑一个单元格时，cellBeginEdit事件就会被激活，其中需要设置editSettings属性以及其子属性，editSingleCell必须设置为 “true”。
语法:
$('Selector').on("cellBeginEdit", function (event) {
// Code
});
