极客教程jQWidgets jqxGrid cellselect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。jqxGrid被用来说明一个jQuery widget，它以表格形式显示数据。此外，它完全支持与数据的连接，以及分页、分组、排序、过滤和编辑。
当一个显示的jqxGrid的单元格被选中时，cellselect事件被激活。
语法:
$("#Selector").on('cellselect', 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;
});
