jQWidgets jqxTreeGrid 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、经过优化、独立于平台且得到广泛支持的框架。 jqxTreeGrid用于以树状结构表示数据。此小部件可用于显示多列分层数据、数据分页、排序和过滤、数据编辑、列大小调整、固定列、条件格式、聚合和行选择。这些小部件还从任何类型的数据源（例如 XML、JSON、Array、CSV 或 TSV）读取和显示数据。

cellValueChanged事件用于在指定 jqxTreeGrid 的单元格值发生更改时触发。

句法：

$('#treeGrid').on('cellValueChanged',  function (event) {
    // Argument of the Event
    var args = event.args;
    // The cell value
    var value = args.value;
    // Old cell value
    var oldValue = args.oldValue;
    // Row data.
    var row = args.row;
    // Row key
    var rowKey args.key;
    // Column data field.
    var dataField = args.dataField;
});
