极客教程jQWidgets jqxDataTable pageChanged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。这也被用来显示来自各种数据源的数据，如XML、JSON、Array、CSV或TSV。
pageChanged事件是用来在指定的jqxDataTable的当前页面被改变时触发的。
语法:
$('#dataTable').on('pageChanged',
function (event)
{
// event args.
var args = event.args;
// page num.
var pageNum = args.pagenum;
// old page num.
var oldPageNum = args.oldpagenum;
// page size.
var pageSize = args.pagesize;
});
