极客教程jQWidgets jqxGrid排序事件
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、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。
当显示的jqxGrid被排序时，排序事件被激活。
语法:
$("#Selector").on("sort", function (event) {
// Arguments of the event
var args = event.args;
// Information of the sorting
var sortInfo = event.args.sortinformation;
// Direction of the sorting
var sortdirection =
sortInfo.sortdirection.ascending ?
"ascending" : "descending";
// Data field of the column
var sortColumnDataField = sortInfo.sortcolumn;
});
