jQWidgets jqxGrid cellunselect 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、经过优化、独立于平台且得到广泛支持的框架。 jqxGrid用于说明以表格形式显示数据的 jQuery 小部件。此外，它完全支持连接数据，以及分页、分组、排序、过滤和编辑。

每当未选择显示的jqxGrid的单元格时，都会激活cellunselect事件。

句法：

$("#Selector").on('cellunselect', function (event) {

   // Arguments of the event
   var args = event.args;
  
   // Text of the column
   var column = $("#Selector").jqxGrid(
      'getcolumn', event.args.datafield).text;
  
   // Data field of the column
   var dataField = event.args.datafield;
  
   // Bound index of the row
   var rowBoundIndex = event.args.rowindex;
  
   // Value of the cell
   var value = args.value;
});
