jQWidgets jqxDataTable cellValueChanged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。

当指定的jqxDataTable的单元格值发生变化时，会触发cellValueChanged事件。

语法:

$('Selector').on('cellValueChanged',  
  function (event) {

    // Event args
    var args = event.args;

    // Cell value
    var value = args.value;

    // Old cell value
    var oldValue = args.oldValue;

    // Row data
    var row = args.row;

    // Row index
    var index = args.index;

    // Row's data bound index
    var boundIndex = args.boundIndex;

    // Row key
    var rowKey = args.key;

    // Column data field
    var dataField = args.dataField;
});
